Product Overview

The GE Fanuc IC694ALG221 is a four-channel analog current input module used with PACSystems RX3i controllers to acquire 0–20 mA and 4–20 mA process signals. It converts field current loops from transmitters and signal conditioners into digital values for monitoring, scaling, and closed-loop control functions within the PLC/PAC system.
