Internal Design and Analog Conversion

This analog input module uses a 16-bit ADC for precise signal conversion. A multiplexer scans all four channels sequentially for processing. The GE IC200ALG432B configures each channel independently for current or voltage. Four 0.1 µF capacitors filter high-frequency noise from input signals. An onboard microprocessor linearizes and scales the digital values. Consequently, this module delivers accurate analog readings for process control applications.

Installation and Wiring Guide

First, mount this module onto a standard 35 mm DIN rail securely. Next, wire your analog sensors to the input terminals (channels 1-4). Use shielded twisted-pair cables for all analog signal connections. Configure each channel’s input type using the VersaMax configuration software. The module provides a green LED for status indication. This analog input module works with all VersaMax PLC systems including IC200CPU series. Always connect the shield drain wire to earth ground for noise reduction.
