    DIN-Rail Mount Interface Relays

    Isolate input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal. These relays interface between your controller and components—they receive a signal from the controller to switch power on or off to the components. All have an LED indicator that shows you if your switch is actuated, so you know it’s connected and wired correctly. Use them to communicate signals to devices like motors or sensors. Mount them on 35 mm DIN rail (also known as DIN 3 rail).

    Fit these relays where standard spade-terminal relays are too big. You can connect them three ways. Plug them into a socket (sold separately), connect them with quick-disconnect terminals, or solder wires directly to the terminals. An LED indicator shows you the status of the relay, so you know it’s connected and wired correctly.
    4 Circuits Controlled—Relays that control 2 or more circuits have a lockable test button, so you can test their function. When you press the button, the relay switches contacts. Use this button when checking a relay for proper function before installing it, or when investigating issues with wired relays.
    Sockets with Screw Terminals—Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. You can also mount them to a flat surface using screws.

    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.

    Smart Multifunction Monitoring Relays

    Image of ProductInUse. Front orientation. Monitoring Relays. Smart Multifunction Monitoring Relays.
    Remotely control these relays through an app on your smartphone—they simultaneously monitor phase, voltage, and frequency. The downloadable app lets you change the tripping range, modify settings, and save programs to apply to multiple relays. Tap your smartphone or tablet to the relays to connect to them. They use NFC (near field communication), so you don’t need to manually pair them like Bluetooth devices.
    You’ll often see these relays used to protect motors, generators, and other three-phase circuits from burning out or overheating. They'll switch the circuit off if they detect voltage or frequencies outside of the set range or phase loss, imbalance, or reversal. You can see that they're wired correctly and when they're actuated based on the LED indicators. Rated IP20, they have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on a 35 mm DIN rail (also known as DIN 3 rail) for fast installation.

    8 Terminals

    Reduce connection errors on circuit boards that control machine guards and other safety devices. Also known as force-guided contact relays, they have contact pairs that won’t close at the same time, even if contacts stick or weld shut. These relays take up less space on a board than those with electrical wiring because their solder pin terminals mount directly through circuit board holes. Use them to control high-power components, such as fans and heaters, from a low-power circuit.

    Screw Terminals

    Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.
    Screw Terminals—Relays with screw terminals are considered interface relays, so they’re placed between your controller and components to isolate the input and output circuits. This means they protect your component from voltage spikes while amplifying the relay’s signal and reducing interference for reliable transmission. They are often used for switching applications, such as small motors and pilot lights. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail).

    Interface Safety Relays

    Image of Specification. Front orientation. Contains Annotated. Safety Relays. Interface Safety Relays.
    These relays pair the transmission reliability of an interface relay with the fail-safe operation of a safety relay. Use them to communicate signals to devices like motors or sensors. They have interlocking contacts—also known as force-guided or mechanically linked contacts—so opposing contacts won't close at the same time. This minimizes the chance of arcing, so electricity won't jump across the contacts and interfere with your relay or system. They also have an interface that isolates input and output circuits to prevent damage from voltage spikes, reduce signal interference, and amplify signal. Mount them on 35 mm DIN rail (also known as DIN 3 rail). The relays disconnect from the socket for quick replacement.

    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).
    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—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.
    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.
    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.
    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.
