Description

Product Description

The IC694ALG392 (GE Fanuc RX3i) is an 8-channel analog output module designed for precise process control in PACSystems environments. It converts digital signals from the CPU into high-accuracy voltage or current outputs, enabling reliable control of valves, motors, drives, and other field devices.

This module allows independent configuration of each channel for voltage or current output, offering high-resolution conversion and rapid update rates. Advanced diagnostics, including open-wire detection in current mode, help maintain system reliability. The module is compatible with both RX3i and Series 90‑30 PLC systems, supporting flexible integration in modern industrial applications.
