The ABB Bailey IMDSO03 (6636037L1) is a high-reliability digital output slave module used in the INFI 90 distributed control system (DCS). As part of the ABB Bailey control infrastructure, this module is engineered to manage the activation and deactivation of discrete field devices such as relays, solenoids, motor starters, and alarms.
By receiving control signals from a higher-level controller, the IMDSO03 interprets digital commands and converts them into corresponding output signals to directly drive connected field hardware. With strong isolation, stable performance, and seamless integration capabilities, this module is a trusted choice in critical process control environments.
