ABB 3ASC25H705 DASA110 Advant Digital I/O Controller PCB Module Core Function This rack-mounted plug-in digital control card is a core I/O processing unit for ABB Advant Master DCS automation systems. It provides isolated digital input and relay output signal collection and logic execution for process field devices. It reads binary sensor, limit switch, interlock and safety contact signals via 16 DI channels, drives 8 mechanical relay outputs to control valves, contactors, alarms and auxiliary motor starters. The board communicates real-time status data to the Advant master controller via proprietary backplane bus, executes local interlock logic without relying on central CPU, and provides surge isolation and short-circuit protection for field wiring in power, pulp & paper, chemical and me
