Programmable logic controller

The Click PLC is the first of a range 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 and free programming software 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. The unit features eight inputs and six outputs, available in four combinations of built-in I/O types. For expansion, 11 option modules are available for flexible system configuration up to 142 I/O. All Click CPUs support 8K steps of flash EEPROM program memory and 8K words of data memory. Two 24 VDC power supply options, with either 0.5 or 1.3 A outputs, can be used to power the PLC.

The Click PLC system’s space-saving design requires no mounting base; up to eight modules can be attached to the Click CPU module via an integrated expansion port on the sides of the modules and secured by locking tabs on the top and bottom of all modules.

Click CPU units also feature two built-in RS232 RJ12 communications ports. One port supports Modbus RTU protocol and can be used as the programming port. The second port is a general-purpose port with user configurable communications parameters and supports either Modbus RTU or ASCII protocols. Both communications ports supply 5 VDC, allowing connection of the C-more Micro HMI panel without an additional power supply.

Click features user-friendly downloadable programming software, the tools, layout and interactivity allowing quick and intuitive program development, and pre-wired I/O cables are also available.
