Control multiple timing functions from your electrical cabinet—these timer relays mount to 35 mm DIN rail (also known as DIN 3 rail), which is the most commonly used size. UL Listed, C-UL Listed, and CE Marked, these relays meet American, Canadian, and European safety standards.

Timer Relays with Delayed, Interval, Switch-On, and Repeat Cycles

With six different functions, these timer relays have a broad range of applications. Use them to precisely control machines such as conveyors, lighting systems, and electric motors.

The delayed start (delay-on-make) 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.

The delayed switch-on with delayed switch-off function uses a switch instead of 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.

The delayed switch-off (delay-on-break) 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.

The interval 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.

The switch-on (single-shot) 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.

The repeat cycle function alternates between an on cycle and off cycle of equal durations until input voltage is removed. A common example would be a flashing light.

Timer Relays with Asymmetrical Repeat Cycles

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

The asymmetrical repeat cycle 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.

The switch-on asymmetrical repeat cycle function is activated with a switch instead of input voltage. 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.

With no moving parts, these solid state relays have an extended service life. Mount directly to 35 mm DIN rail or attach to a flat surface. They provide a variety of timing functions in one relay.

Use relays with DIP switches for more precise control than knobs; they make it easier to set multiple relays to the same timing range.

Maximize space inside your control cabinet. The included relay socket mounts to 35 mm DIN rail; the relay disconnects from the socket for easy replacement. These relays provide a variety of timing functions in one relay.

Plug relays into relay sockets for fast installation and replacement. They provide a variety of timing functions in one relay.

Relay socket (sold separately) mounts to 35 mm DIN rail or flat surfaces.

Smaller than standard multifunction timer relays, these relays save space in your control cabinet. They plug into relay sockets for fast installation, and provide a variety of timing functions in one relay.

Relay socket (sold separately) mounts to 35 mm DIN rail or flat surfaces.

Install relays in a panel cutout or plug into a relay socket. They provide a variety of timing functions in one relay.

Single-circuit relay has two types of delayed switch-off (delay-on-break) functions and two types of signal on/off delay functions.

Relay socket (sold separately) mounts to 35 mm DIN rail or flat surfaces.

Mounting bracket (sold separately) is required to mount in a panel cutout.

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.

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.
