GE IC694ALG221 Analog Input Module

Overview

The IC694ALG221 is a high-performance analog input module for the PACSystems RX3i series. It provides four differential input channels for precise current signal acquisition. The module accepts 0–20 mA or 4–20 mA signals, making it ideal for industrial sensors. Users can connect pressure transducers, flow meters, and temperature transmitters. It delivers fast 2 ms conversion per channel and advanced diagnostics for mission-critical applications. The module suits energy, manufacturing, and process control sectors. It mounts easily on panels or DIN rails and ensures channel-to-channel isolation.
