Timer relays with delayed, interval, switch-on, and repeat cycles have a broad range of applications. Use them to precisely control machines such as conveyors, lighting systems, and electric motors.

Delayed Start (Delay on Make) Timer—This function allows you to set how long it takes for the relay to turn on after input voltage is applied. For example, a drill starts pumping lubricant immediately, but it does not start rotating until the set time has elapsed.

Delayed Switch Off (Delay on Break) Timer—This function uses a switch instead of input voltage. When the switch is turned off, the relay remains on for a programmed amount of time before turning off. For example, a projector’s light is turned off with a switch, but its cooling fan continues to run for a set time.

Delayed Switch-On with Delayed Switch-Off Timer—This function uses a switch instead of input voltage. It allows you to set how long the relay takes to turn on after a switch is turned on, and how long it will stay on after the switch is turned off. For example, a furnace turns on, but the fan doesn’t start pushing air through the vents until it has been heated. When the furnace turns off, the fan keeps blowing to circulate all the hot air.

Delayed-Pulse Timer—This function uses input voltage to turn on the relay for a brief period after a preset time. For example, a light flashes a few seconds after a door closes.

Interval Timer—This function uses input voltage to turn on the relay for a programmed amount of time. For example, when a part moving down a conveyor reaches a certain location, a cleaning spray comes on for a set time.

Interval Switch-Off Timer—This function requires a switch to activate the relay, which stays off for the programmed amount of time. For example, lights in a storage room are turned on with a switch and stay on for a set time before turning off.

Switch on (Single Shot) Timer—This function requires a switch to activate the relay, which stays on for the programmed amount of time. For example, lights in a storage room are turned on with a switch and stay on for a set time before turning off.

Repeat-Cycle Timer—This function starts with an on cycle and then alternates between an on cycle and off cycle of equal durations until input voltage is removed. A common example would be a flashing light.

Start-Off Repeat Cycle Timer—This function starts with an off cycle and alternates between an on cycle and off cycle of equal durations until input voltage is removed. A common example would be a flashing light.

Switch Fixed On/Off Timer—This function requires a switch to activate the timing function instead of the input voltage (which is applied the entire time). It keeps the relay on whenever the switch is closed; it will only turn off if the switch is open.

Timer Relays with Asymmetrical Repeat Cycles

1 Circuit

Controlled

Use timer relays with asymmetrical repeat cycles when your repeat cycles have different on- and off-cycle durations.

Asymmetrical-Repeat-Cycle Timer—This function switches the relay on and alternates between different durations of on and off for as long as input voltage is applied. For example, a sprinkler system sprays in short bursts followed by longer rest periods, on and off until input voltage is removed.

Start-Off Asymmetrical Repeat Cycle Timer—This function switches the relay off and alternates between different durations of on and off for as long as input voltage is applied. For example, an irrigation system receives a signal and starts in the off state, allowing water to fill before switching on to start pumping.

Switch-On Asymmetrical Repeat Cycle Timer—This function switches the relay on and alternates between different durations of on and off for as long as input voltage is applied. It requires a switch to activate the timing function instead of the input voltage that’s being applied the entire time. You could use this function to turn on an electric motor for a short period and then turn it off for a longer rest period, repeating that pattern until the switch is turned off.

Switch-Off Asymmetrical Repeat Cycle Timer—This function switches the relay off and alternates between different durations of on and off for as long as input voltage is applied. It requires a switch to activate the timing function instead of input voltage that’s being applied the entire time. It could be used to turn on an electric motor for a short period and then turn it off for a longer rest period, repeating that pattern until the switch is turned off.

Dual-Channel DIN-Rail Mount Multifunction Timer Relays

Control two steps of an electrical process from a single relay—with two fully independent channels and 30 different functions, these relays give you a wide range of possibilities. Each channel has its own output, so you can run two different functions (one per circuit) at the same time. Mount them to 35 mm DIN rails (also known as DIN 3 rail) and connect them to lighting systems, conveyors, electric motors, and other systems. These relays are UL Listed, C-UL Listed, and CE Marked, meaning they meet U.S. and international safety standards.

View times, function names, and on/off status for both channels at once using the digital display. You can program these relays with a joystick on the face, which is easier to use than the rotary dials on traditional relays. You can also program them using an Android phone with NFC (near field communication) capability, which is commonly used for mobile payment. Once you select the functions you need, hold the phone against the relay to program.

Connect switches to inputs on these relays to trigger, pause, and reset functions. Turning on a switch connected to the pause input stops functions until the switch is turned off. A switch connected to the reset input will start functions from the beginning. If the relay is actively receiving a signal, the function will restart right away. If there is no signal, the function will stop and reset, so it starts from the beginning the next time it’s triggered. You can use switches to pause or reset both channels at once, or for one channel only.

Although these relays have 30 different functions, they all fall into 10 categories. Within these categories, you can select different functions to allow you to add a switch, program a delay, or change how the relay responds to a trigger (turning on or off, pausing, or resetting).

Delayed Start (Delay on Make) Timer—These functions allow you to set how long it takes for the relay to turn on after input voltage is applied. For example, a drill starts pumping lubricant immediately, but it does not start rotating until the set time has elapsed.

Delayed Switch Off (Delay on Break) Timer—These functions use a switch instead of input voltage. When the switch is turned off, the relay remains on for a programmed amount of time before turning off. For example, a projector’s light is turned off with a switch, but its cooling fan continues to run for a set time.

Delayed Switch-On with Delayed Switch-Off Timer—This function uses a switch instead of an input voltage. It allows you to set how long it takes the relay to turn on after a switch is turned on, and how long it will stay on after the switch is turned off. For example, a furnace turns on, but the fan doesn’t start pushing air through the vents until it has been heated. When the furnace turns off, the fan keeps blowing to circulate all the hot air.

Interval Timer—These functions use input voltage to turn on the relay for a programmed amount of time. For example, when a part moving down a conveyor reaches a certain location, a cleaning spray comes on for a set amount of time.

Switch on (Single Shot) Timer—These functions require a switch to activate the relay, which stays on for the programmed amount of time. For example, lights in a storage room are turned on with a switch and stay on for a set time before turning off.

Repeat-Cycle Timer—When input voltage is applied, the relay turns on for a duration, then off for the same duration. They alternate between the two until input voltage is removed. For example, a flashing light stays on and off for equal periods of time.

Asymmetrical-Repeat-Cycle Timer—These functions start with an on-cycle and then have an off-cycle, but these cycles have different durations. The cycles repeat until input voltage is removed. For example, a sprinkler system sprays in short bursts followed by longer rest periods, on and off until input voltage is removed.

Manual-Switch-Control Timer—Use these functions to turn the relay on and off with a switch.

Fixed On/Off Timer—The on function keeps the relay on whenever input voltage is applied; it will only turn off if the voltage is removed. The off function keeps the relay in an off state, even if input voltage is applied.

Switch-On Asymmetrical Repeat Cycle Timer—These functions require a switch to activate the timing function. The input voltage is applied the whole time, and when you turn the switch on, the relay begins with an on-cycle followed by an off-cycle. These cycles have different durations, and they repeat until you turn the switch off. They could be used to turn on a motor or other system for a short period and then turn it off for a longer rest period, repeating that pattern until the switch is turned off.

Proximity Sensor Compatability (PNP and NPN)—Use relays with proximity sensor compatibility to activate functions when your sensor is triggered, such as when an object approaches or a liquid level changes. These relays are compatible with both standard styles of sensors, PNP and NPN, and are often used for warning signals, motion-detecting light and heating systems, and automated assembly lines.

Mount these timer relays in a panel cutout or plug them into a relay socket for quick installation. Capable of fast switching, they are solid state and have no moving parts, so they require less maintenance, last longer, and are quieter than mechanical relays. Unlike standard relays that switch on and off immediately, timer relays delay before the circuit stops or starts.

Repeat Cycle—Relays with a repeat cycle alternate between an on cycle and off cycle of equal durations until input voltage is removed. A common example would be a flashing light.

Asymmetrical Repeat Cycle—Relays with an asymmetrical repeat cycle begin in an on state, then alternate between different durations of off and on for as long as input voltage is applied. For example, a heating system starts with an on period, then switches to an off period once the desired temperature is reached.

Compact PLCs

PLC Shown with Two Expansion

Modules (Sold Separately)

Support for up to 188 inputs and outputs—these PLCs are ideal for basic tasks where more advanced PLCs would be overkill, such as operating lighting and HVAC systems. They’re also known as smart relays. Connect these PLCs to your Ethernet network to control devices anywhere in your facility. They use an open communication protocol, so you can mix and match devices from different manufacturers. Mount them to 35 mm DIN rail in your electrical cabinet or use mounting brackets (sold separately) to secure them to a flat surface.

You’ll need a license key (sold separately) for the manufacturer’s software. Write your program in common PLC languages, such as Ladder Logic and Structured Text, then transfer your program to the PLC with an Ethernet cord. Use the software to monitor, test, and troubleshoot issues in real time. Add a memory card to back up, store, and transfer programs to multiple machines.

These PLCs have digital inputs and outputs.

PLCs with Display

Image of Product. Front orientation. PLCs. Compact PLCs, Display.

These PLCs have a screen and keypad that let you adjust timers and change basic settings without connecting to your computer. You can also view system errors and warnings for quick troubleshooting.

Screw Terminals—Screw terminals are the most common wire connection—insert your wires and tighten the screws to secure them.

Spring-Clamp Terminals—Spring-clamp terminals hold wires with a clamp instead of screws, so connections stay secure, even with vibration.

Relay Output—PLCs with relay outputs are ideal for devices that switch a few times per minute, such as compressors.

Transistor Output—PLCs with transistor outputs are ideal for devices that switch multiple times per second, such as indicator lights and stepper motor drives. They’re PNP outputs, also called sourcing outputs, so they work only with NPN devices. If you need to connect different devices, use an output converter or signal converter (both not included).

Analog Input Signal—PLCs with analog inputs receive signals from devices that monitor temperature, pressure, and other measurements that vary.

Smart DIN-Rail Mount Multifunction Timer Relays


1 Circuit Controlled	2 Circuits Controlled

Whether installed in an electrical cabinet or hard-to-reach area, these timer relays are controlled remotely from your smartphone. They connect to your phone via a free downloadable app with NFC (Near Field Communication), so you can set time delay ranges, adjust settings, and save programs. An LED indicator on the relay shows that your switch is on and whether it’s actuated. Mount them directly to 35 mm DIN rail (also known as DIN 3 rail).

Although these relays have 30 different functions, they all fall into 11 categories. Within these categories, you can select different functions to allow you to add a switch, program a delay, or change how the relay responds to a trigger (turning on or off, pausing, or resetting).

Repeat-Cycle Timer—These functions start with an on cycle and then alternate between an on cycle and off cycle of equal durations until input voltage is removed, such as with a flashing light.

Manual-Switch-Control Timer—Use these functions to turn the relay on and off with a switch.

Star-to-Delta Timer—These functions allow you to set the time delay within the relay's range to switch contacts on a three-phase motor from star to delta configuration. Since star configuration takes less voltage to start than delta, these functions prevent voltage dips that often happen when a motor starts and are gentler on mechanical parts.

Solid State Surface-Mount Timer Relays

Attach these relays to a flat surface using the mounting hole. They have no moving parts, so compared to mechanical switches, they require less maintenance, last longer, and are quieter.

Repeat Cycle—Repeat cycle relays turn on for a duration, then off for the same duration. They alternate between the two cycles until input voltage is removed. A common example would be a flashing light.

Solid State DIN-Rail Mount Multifunction Interface Timer Relays

Considered solid state because they don’t have any moving parts, these timer relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, preventing damage to your components from voltage spikes, amplifying the relay's signal, and reducing signal interference. Use these relays with switching applications, such as small motors and pilot lights. They offer multiple timing functions in one relay. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relays disconnect from the socket for easy replacement.
