The ioPro 8AI-I-ISO inputs are fully isolated from input to logic and between inputs. This module is ideal for monitoring existing current signals which are isolated from each other and cannot be connected to a common point of reference. The standard setting for the 8AI-I-ISO module is 0 - 20mA input which represents an output value of 0 - 4095 (12 bits) in the corresponding Modbus register. In this range, a reading of 4 mA would give a Modbus value of 819 ±1LSB. To obtain an output value of 0 to 4095 for an input signal of 4 to 20mA the offset switch can be switched on. Also, this module can also be configured for a 0 - 20mA input range or ±20mA input (1 A resolution).
