ABB DI810 Sinking Digital Input Card

Product Description

The ABB DI810 (Part Number: 3BSE008508R1) is a high-density 16-channel binary input card designed for the standard S800 I/O architecture. Utilizing a current sinking configuration, the module divides its input paths into two separate isolated groups of eight channels to prevent electrical fault cross-contamination across critical plant machinery links.
