ABB 3BSE008508R1 (DI810) 16-Channel Digital Input Module 24 VDC

Product Description

The 3BSE008508R1 (DI810) is a 16-channel digital input module for ABB’s AC 800M and System 800xA platforms. It accepts 24 VDC discrete signals and features two galvanically isolated groups of 8 channels each, improving noise immunity and fault containment. Designed for direct mounting on ABB I/O baseplates, it pairs with TU810–TU850 termination units for flexible field wiring.

FAQ
Q: Does it support hot-swap?
A: Yes, with compatible I/O stations and controller configuration.

Q: Can it read dry contacts?
A: Only if externally powered; the DI810 requires a 24 VDC source at the input.

Q: Difference vs. DI801?
A: DI810 has fewer channels (16 vs. 32) but adds dual-group isolation—better for noisy or safety-critical circuits.
