Description
Overview
The ABB IMDSO02 is a 16-point digital output module designed for Bailey INFI 90, Net 90, and Symphony Harmony distributed control platforms. It translates controller commands into discrete field output signals for driving external electrical devices in industrial control environments.
It is engineered for high-reliability switching applications where stable actuation, electrical isolation, and fault protection are required for continuous operation.
Functional Role
The IMDSO02 operates as an output interface between the INFI 90 control system and field-level actuators. It receives digital commands from the system backplane and energizes 24 VDC output channels to control devices such as relays, solenoids, indicators, and interlocking circuits.
Each channel operates independently, allowing distributed control of multiple field devices within a single module.
