Product Overview
The ABB DI810 3BSE008508R1 is a 16-channel 24 V DC digital input module designed for the ABB S800 I/O system. This compact and robust module enables reliable acquisition of field digital signals in demanding industrial automation environments. The DI810 is widely deployed in distributed control systems (DCS) such as ABB 800xA and AC 800M, where high-density and efficient signal processing is required.
This module supports single-ended input channels with non-isolated configurations, making it ideal for systems where common ground referencing is acceptable. The integration of LED indicators and support for standard terminal units enhances ease of installation, diagnostics, and long-term maintenance.
