The Quickstart guide is a great resource for more information about Installation and wiring. It ships in the box with your CLICK, and you can download it here.
The Hardware Reference Guide is the most complete source for this information.
The CLICK PLC system does not require a mounting base or rack, which saves money and space. CLICK uses only as much space as needed for a specific application
The CLICK CPU and I/O modules are connected together via an integrated expansion port on the sides of the modules and sliding locking tabs on the top and bottom of all modules.
The ZIPLink wiring system eliminates the normally tedious process of wiring PLC I/O to terminal blocks. Simply plug one end of a ZIPLink pre-wired terminal block cable into your I/O module and the other end into a ZIPLink connector module. It’s that easy. ZIPLinks use half the space, at a fraction of the total cost of terminal blocks.
