GE Fanuc IC200ALG320 VersaMax 4-Channel Analog Output Module

The GE Fanuc IC200ALG320 is a 4-channel analog output module for the VersaMax I/O system. It delivers precise 0-10 VDC signals with 12-bit resolution, ideal for controlling VFDs, actuators, and proportional valves in automated environments.

Technical Overview

The GE Fanuc IC200ALG320 belongs to the VersaMax I/O family, serving as a high-performance analog output interface for programmable logic controllers (PLCs) and distributed I/O systems. This module provides four independent channels that convert digital CPU data into precise 0-10 VDC analog signals. Designed for versatility, the IC200ALG320 functions as a remote node or local I/O, allowing industrial automation systems to control actuators, variable frequency drives (VFDs), and other voltage-controlled field devices with high accuracy.

Functional Performance

This output module features a high-resolution digital-to-analog converter that ensures smooth signal transitions and consistent control performance. Each channel operates independently, although they share a common return. The IC200ALG320 continuously monitors the health of the output circuitry and reports status data back to the controller. Furthermore, the module maintains its last state or resets to a default value upon loss of communication, providing a critical safety layer for industrial processes.
