AutomationDirect's Click PLC designed for first-time users and experienced programmers

AutomationDirect introduces the Click PLC, the first in a series of inexpensive PLC components designed to offer practical features in a compact yet expandable design. The 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, the Click CPU unit can function as a complete PLC system. The unit features eight inputs and six outputs and is available in four combinations of built-in I/O types. For expansion, eleven option modules are available for flexible system configuration, offering 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 .5A or 1.3A 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 can be secured by locking tabs on the top and the bottom of all modules.

Click CPU units also feature two built-in RS-232 RJ12 communications ports. One port supports Modbus RTU protocol only and can be used as the programming port. This port can also connect the CPU to a Modbus RTU network as a slave device. 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 five VDC, allowing connection of the C-more Micro HMI panel without an additional power supply. LED indicators located at each port indicate when the port is transmitting or receiving.

As part of the Click line of products, pre-wired I/O cables are also available. Available in pre-wired and ready-to-wire configurations, the cables help eliminate the labor-intensive process of wiring PLC I/O to terminal blocks.
