ABB Bailey IMDSI14 Digital Slave Input Module 16-Channel

Description

The ABB IMDSI14 is a high-density digital input slave module engineered for the Bailey INFI 90 and Symphony Plus distributed control systems. It serves as the primary interface for acquiring discrete status signals from field equipment, such as limit switches, pushbuttons, and relay contacts. The module processes up to 16 independent inputs, converting field-side voltage states into digital data for the master controller. Designed for high-speed logic execution, the IMDSI14 provides the essential data required for sequencing, interlocking, and alarm monitoring in critical industrial process environments.
