The ABB DI810-1 (Part Number: 3BSE008509R1) is a high-performance Digital Input (DI) PCB module designed for use in ABB’s S800 I/O system, which forms a key part of the ABB 800xA Distributed Control System (DCS). As a 16-channel 24 VDC digital input module, the DI810-1 is engineered to receive status signals from field devices such as switches, sensors, and contactors, and transmit these signals accurately to the control system.

This PCB module version is primarily intended for module-level replacement or integration within embedded control solutions or OEM assemblies. Despite being a bare board, the DI810-1 maintains all performance characteristics of its full module version and is designed to withstand industrial operating conditions.

It offers galvanic isolation, channel monitoring, and diagnostics, ensuring the highest level of system reliability and fault detection—making it a crucial component for mission-critical automation environments.
