DI810 16-Channel Digital Input Module 24V DC S800 I/O | ABB

The Original New ABB DI810 3BSE008508R1 is a 16-channel digital input module for the ABB S800 I/O system, designed to interface 24V DC discrete field signals with ABB control systems including AC 800M controllers and the 800xA distributed control system (DCS). It provides 16 isolated digital inputs arranged in two groups of 8 channels, supporting both sinking and sourcing field devices. This module is suitable for monitoring pushbuttons, limit switches, relay contacts, motor status feedback, and safety interlocks in process control, manufacturing automation, and utility infrastructure applications.

Core Engineering Highlights:
16 isolated digital inputs (2 groups of 8 channels) | 24V DC nominal (18-30V DC range) | 6-7 mA per channel @ 24V DC | Sink/source configurable | 500V AC isolation (channel-to-system) | Selectable digital filtering: 2, 4, 8, or 16 ms | Hot-swappable | DIN rail mounting via Module Termination Unit (MTU) | -40°C to +70°C operating temperature | IP20 protection
