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.

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.

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).

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

Fixed On/Off—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 (Single-Shot)—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.

Delayed Start (Delay-on-Make)—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)—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—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—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.

Repeat Cycle—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—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.

Switch-On Asymmetrical Repeat Cycle—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.

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.

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.

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.

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).

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.

Smaller than other PLCs, these controllers save space in your control cabinet. They combine the functionality of a relay, timer relay, and switch in one unit, so you can program simple automation jobs. All have two types of delayed start (delay-on-make) and two types of delayed switch-off (delay-on-break) timing functions. They have passed strict U.S. and Canadian safety standards, and they’re IP20, which prevents fingers and other objects from making contact with live circuits. Mount them to a 35-mm DIN rail.

Controllers with a display make it easy to monitor or modify your system directly on the unit. Controllers without a display eliminate the risk of accidental adjustments while toggling through information or tampering by unauthorized users.

Program these controllers by connecting them to a computer and installing the required software (sold separately). After the initial programming, these controllers can be updated remotely by a human-machine interface (HMI) or computer.

Set these switches to delay activation by up to five seconds after detecting an object. A built-in relay produces AC voltage output. They’re often used with older programmable logic controllers (PLCs). They detect the presence or absence of an object moving at high speeds with a light beam. All are rated IP66 for protection against washdowns.

Direct sensing switches detect objects when light reflects back from the object. The transmitter and receiver are in the same housing, so they fit in confined spaces.

Receiver switches detect objects when an object breaks the light beam between the transmitter and receiver (both included). They have a longer sensing distance than direct-sensing and reflector switches.

Reflector switches detect an object when it passes between the switch and the reflector, interrupting the beam. They have a longer sensing distance than direct-sensing switches.

Set these switches to delay activation by up to fifteen seconds after detecting an object. They have a highly flexible fiber-optic cable and small sensing end, making it easy to position these switches in hard to reach areas. They detect the presence or absence of an object moving at high speeds with a light beam. Adjust the intensity of the light beam to better detect shiny or translucent objects. The fiber-optic cable can be cut to length. All are rated NEMA 6P and IP67 for protection from corrosion, washdowns and temporary submersion.

Direct sensing switches detect objects when light reflects back from the object. The transmitter and receiver are in the same housing, so they fit in confined spaces.

Detect irregularly shaped items with a band of light up to 10 times larger than the beam on a standard photoelectric switch. The wide beam makes them a great choice when material moving down your line varies in size and shape. Because they’re photoelectric, they don’t make contact with items like other actuators do, and they can detect objects that are moving quickly. They produce PNP or NPN signal output. To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included).

Direct sensing switches project light onto an object and then detect the reflection to actuate. The transmitter and receiver are in the same housing, so these switches fit in tight spaces. Use them to detect small material with irregular shapes, such as circuit boards. Those with a delayed off function can stall activation by up to one second after sensing an object.

Adjustable switches can increase the intensity of the light beam to better detect shiny or translucent objects.

Send a signal to turn equipment on and off from up to 150 feet away without having to run electrical wire. These relays have an enclosure to protect the terminals from dust and accidental bumps. They can be set to transmit, receive, or both at once. You’ll need at least two relays to switch a device. They have an alarm that can be set to check for certain conditions before transmitting a signal. For example, you could set these relays to send a signal to turn on an air conditioner if all windows are closed. The repeat function extends the transmitting signal through a maximum of two receiving relays.

Relays that are set to transmit can be linked up to as many receiving relays as you need. Relays set to receive can be linked up to 30 transmitting relays. All relays connect to dry contacts on your switch, sensor, or controller. Use the wire leads to connect them to a power source.
