June 15, 2009 -
Configured via software, CLICK Programmable Logic Controllers include analog CPU modules with 2 analog inputs and 2 outputs, voltage ranges up to 5 Vdc, and current up to 20 mA. Modules also feature one RS-485 and two RS-232 communication ports, real-time clock, and battery backup for internal SRAM. Units are differentiated by discrete I/O; all have 4 dc inputs, and choice of 4 dc sinking, dc sourcing, or relay outputs.
