CPU Modules
There are 11 CLICK CPU modules available in three classes, each with different combinations of built-in I/O types. The CLICK CPU modules all offer the same performance, instruction set, and support the available optional I/O modules. With the built-in I/O a CPU can be used as a ready-to-go PLC control system without any additonal I/O modules.

I/O Modules

A variety of I/O modules are available for the CLICK PLC System. Up to 8 I/O modules can be connected to a CLICK CPU module to expand the system I/Ocount and meet the needs of a specific application. CLICK on a part number for complete I/O module specifications and wiring diagrams. These tables list the discrete option modules that are supported by the CLICK PLC. Use our Configuration Tool to quickly configure a CLICK PLC with the option modules needed for your application, then CLICK over to the webstore to complete your purchase.
