INFI 90 Digital Input Module 16-CH | ABB IMDSI22 Bailey

Product Description

High-Density Discrete Signal Processing

The IMDSI22 (Model: IMDSI22) is a high-performance digital input module designed for the ABB Bailey INFI 90 Distributed Control System (DCS) and Symphony Harmony platforms. It functions as a critical interface for acquiring 16 independent discrete (on/off) signals from field devices such as limit switches, proximity sensors, and push buttons. The IMDSI22 (Part Number: IMDSI22) converts these raw field inputs into digital data for the system's Multi-Function Processors, ensuring accurate monitoring and logic execution in mission-critical industrial environments.
