ABB DI810 3BSE008508R1 S800 I/O 16-Channel 24 VDC Digital Input Module

Product Description

The DI810 (3BSE008508R1) is a high-reliability 16-channel digital input module designed for the ABB AC 800M controller and System 800xA automation platforms. Operating as part of the S800 I/O family, this module is engineered to interface 24 VDC discrete signals from field equipment—such as limit switches, valve positioners, and motor starters—with the central control system.

To ensure maximum signal integrity and fault containment in industrial environments, the DI810 (3BSE008508R1) features two galvanically isolated groups of 8 channels each. This dual-group architecture significantly improves noise immunity and prevents electrical faults in one group from propagating to the other or to the system backplane. The module is designed for vertical or horizontal mounting on a variety of Module Termination Units (MTUs), providing versatile wiring options for power, water treatment, and chemical process plants.
