Analog CPUs

The CLICK PLC line includes three analog CPU models. The new CPUs feature two analog inputs and two outputs with ranges of voltage up to 5 VDC or current up to 20 mA. The modules include two built-in RS-232 and one RS-485 communication ports, and real-time clock and battery backup for internal SRAM. Analog CPU modules are differentiated by their discrete I/O; all have four DC inputs, and a choice of four DC sinking, DC sourcing or relay outputs. All CLICK CPUs are configured with the easy-to-use programming software, available as a free download. Prices for the analog CPUs start at $129.
