        Features:

        • Digital Input Interface Between Field Devices and S800 I/O Rack Backplane
        • Integrates 16-Channel Digital Signal Acquisition with Individual Channel Isolation
        • Functions in Conjunction with ABB Advant OCS and S800 Series Controllers
        The ABB DSDI120AV1 3BSE018296R1 operates as the Digital Input Board in an S800 I/O rack, providing reliable discrete signal acquisition from field devices to all modules within the system. It continuously receives 24V DC digital input signals from switches, sensors, and proximity detectors and transmits these status indications through the rack backplane to support real-time monitoring and control logic execution of all connected controllers and I/O modules. Consistent signal integrity is standard with the DSDI120AV1 3BSE018296R1, and its configurable input filtering allows adaptation to both slow-acting mechanical contacts and fast-switching electronic sensors.

        The DSDI120AV1 3BSE018296R1 provides essential input functions common to the entire rack, and is a critical component of the control path, directly affecting the proper, normal operation of the overall automation system. One or more DSDI120AV1 3BSE018296R1 digital input boards are required per rack depending on the desired I/O channel count. The DSDI120AV1 3BSE018296R1 occupies a single slot in the rack and can be installed in any standard I/O slot position.

        For expanded digital input applications, the S800 System allows multiple DSDI120AV1 3BSE018296R1 modules to be installed across available slots. In addition to standard single module operation, the distributed configuration also performs coordinated signal processing. The S800 multi-module configuration executes data exchange using the internal ModuleBus specified in the controller options.

        The DSDI120AV1 3BSE018296R1 ABB Digital Input Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
