8.3.2 AC2636 FieldModuleDP 4AI (C) M12
The analogue module AC2636 processes signals in the range of 0/4���20 mA�
The input current is digitalised with a resolution of 16 bit, electrically isolated and
transferred to the higher-level automation device�
The 4 input channels are differential inputs and have a common internal ground
potential�
