Product Overview
The IMASI03 is a high-performance Analog Input Slave Module designed for the ABB Bailey INFI 90 Distributed Control System (DCS). This module serves as the primary interface for acquiring critical process data from field sensors, including pressure transmitters, thermocouples, and flow meters. Engineered for precision, the IMASI03 features a multi-stage conditioning path—including a programmable gain amplifier and a high-resolution ADC—to convert low-level analog signals into digital values for the Master Controller. Its rugged design incorporates signal isolation barriers and open-input detection, ensuring system reliability and safety in the most demanding industrial environments.
