4-3-6 Analog input module wiring
The analog input module, as the remote extension module of the Q series CPU unit, cannot work alone
and needs to be connected to the EC coupler or the right side of the CPU unit. It supports both current
and voltage input. HCFA offers varieties of input ranges and the working range can be modified online
through SDO or COE, where voltage input supports single –ended and differential input.
