The CLICK PLC is the first in a new generation of inexpensive PLC components designed to offer practical features in an easy-to-use, compact yet expandable design. This line of micro-brick PLCs with stackable I/O modules is suitable for first-time users as well as experienced programmers. By itself, a powered CLICK CPU unit can function as a complete PLC system. Up to eight modules can be attached to the CPU module via an integrated expansion port. Features include two built-in RS-232 communications ports and free programming software that includes 21 practical instructions and a combination of relay ladder logic and function blocks.
