Description
Product Description
The GE Fanuc IC693ALG221 is an 8-channel analog input module engineered for the Series 90‑30 PLC platform. It converts analog signals from sensors such as temperature, pressure, or flow transmitters into precise digital values for PLC processing. Designed for versatility, the IC693ALG221 supports multiple input ranges and provides high-resolution measurement with built-in diagnostics for reliable industrial control.
This module offers hot-swappable installation in standard Series 90‑30 rack slots, allowing easy maintenance or replacement without system downtime. Its isolation between channels and the PLC logic ensures signal integrity even in electrically noisy environments, making it suitable for both factory floor and process control applications.
