ABB 3BSE018295R1 Digital Input Module

The ABB DSDI110AV1 (3BSE018295R1) is a digital input board designed for ABB Advant OCS and System 800xA, compatible with S100 I/O systems . Its core function is to collect 24V DC discrete signals from field devices—such as limit switches, pushbuttons, and relay contacts—and convert them into logic states for the controller. It represents an upgraded version of the older DSDI110 and DSDI110A modules.
