PM8AI/I – 8 Current Input Module

The PM8AI/I is a 8 channel current input module. The inputs are isolated from the logic and share a common negative terminal.

The standard setting for the PM8AI/I module is 0 - 20mA input current which represents an output value of 0 - 4095 (12 bits) in the corresponding Modbus register. To obtain an output value of 0 to 4095 for an input signal of 4 to 20mA the offset switch is switched on.
