Industrial Signal Acquisition Scenarios
The ABB Bailey IMDSI22 Numeric Input Slave Module is designed to capture discrete input signals within the ABB Bailey INFI 90 distributed control system architecture. In large-scale industrial facilities, digital input modules collect operational status signals from field equipment and deliver them to the control system for monitoring and automation logic execution.
This module is typically deployed in environments where reliable digital signal monitoring is critical, including:
-
Power generation facilities, where digital signals from protection relays, switchgear, and auxiliary systems must be monitored continuously.
-
Oil and gas processing plants, where valves, pumps, and safety systems provide discrete status signals to the control network.
-
Chemical and petrochemical production, where safety interlocks and equipment status indicators require stable digital input acquisition.
-
Water and wastewater treatment plants, where pumps, gates, and alarms generate continuous digital monitoring signals.
-
Automated manufacturing systems, where sensors, limit switches, and machine indicators provide real-time operational status.
As a slave input module, the IMDSI22 operates in coordination with a master interface module, expanding the digital input capacity available within the automation system.
