Install these relays in a panel cutout or plug them into a relay socket. Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, are quieter, and switch faster. They give you a variety of timing functions in one relay.

Single-circuit relays give you additional flexibility—they have two types of delayed switch-off (delay-on-break) functions and two types of signal on/off delay functions.

Relay sockets (sold separately) mount to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to flat surfaces.

Mounting brackets (sold separately) are required to mount relays into a panel cutout.

Get a variety of timing functions in a single relay. All relays plug into relay sockets (sold separately) for fast installation and replacement.

Relay socket/panel mount relays require a mounting bracket (sold separately) to mount in a panel cutout.

Relay sockets mount to 35 mm DIN rail (also known as DIN 3 rail) or can be mounted to a flat surface.

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).

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—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—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.

Star-to-Delta—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.

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.

Delayed-off relays let you set how long it takes for the relay to turn off after input voltage is removed. For example, a sensor detects when an item has been placed on a conveyor, triggering the relay to start the conveyor belt and a cooling fan. After the item has moved past another sensor, the input voltage is removed to stop the conveyor, while the cooling fan runs for a set time before shutting off.

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.

Relays with a start-off asymmetrical repeat cycle begin in an off state, then alternate 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.

Relay sockets (sold separately) mount to 35 mm DIN rail (also known as DIN 3 rail) or can be mounted to a flat surface.

Mounting brackets (sold separately) are required to mount the relay into a panel.

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.

Add expansion modules to increase the number of inputs and outputs. You can connect up to 11 modules to a controller—for a maximum of 188 inputs and outputs. Choose any modules that support the operating voltage of your controller.

Design and operate up to six simultaneous programs without symbols or technical language—the on-screen instructions use simple English. These PLCs combine the functionality of a relay, timer relay, and switch in one unit so you can program complex automation jobs. All have memory backup to retain programming during power outages. Mount to 35-mm DIN rail.

Add expansion modules to increase the number of inputs and outputs. Use either module on its own, or add one of each, but two of the same module won’t work together.

Remote timer panels monitor and adjust up to eight timers while the controller is operating.

Configure any of your IO Link devices—from sensors to switches—without a PC, outlet, or separate software. Use these programmers to set parameters, check the quality of runs, clone settings for other devices, and more. Whether you’re setting up a device for the first time or adjusting settings, the easy-to-use touchscreen makes for a smooth experience. Since these programmers are powered by a battery and small enough to carry, you can bring them wherever you need.

As soon as you connect your device, these programmers download its IO Device Description (IODD) file. This means you won’t need to manually input device details, saving you time to jump right into programming. Internal storage keeps IODD files and custom settings on hand for you. If you need extra space, insert a microSD card (not included) into these programmers before turning on the connected device.

Plug devices with M8 or M12 connections directly into the sockets on these programmers. If your device has wire leads, use the included adapter.
