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.
