The ABB Bailey IMRAE12 is a high-reliability Analog Input Module used within the INFI 90 distributed control system (DCS). It is designed to acquire, condition, and convert analog signals from industrial field instruments into digital data for process control and monitoring.
As part of ABB’s Bailey automation architecture, IMRAE12 plays a key role in ensuring accurate real-time measurement of process variables such as pressure, temperature, flow, and level. It is widely applied in power generation, petrochemical plants, and heavy industrial automation systems, where precision and signal stability are critical.
