ABB IMDSI15 Bailey Infi 90 16-Channel Digital Input Slave Module

Description

The ABB IMDSI15 is a 16-channel discrete signal acquisition module engineered for the Bailey Infi 90 and Network 90 Distributed Control Systems (DCS). It serves as a high-density interface for monitoring field device states, such as limit switches and relay contacts. This module converts binary field voltages into digital logic while providing robust optical isolation to shield the system backplane from electrical noise. With integrated debouncing and real-time LED diagnostics, the IMDSI15 ensures accurate data collection for critical industrial interlocking and sequence-of-events monitoring.
