ABB DI890 3BSC690073R1 is an eight-channel digital input module with an intrinsic safety interface for the ABB System 800xA S800 I/O family. Its eight channels are arranged as 8 × 1 and are individually galvanically isolated.
ABB documentation lists a rated isolation voltage of 50 V and identifies TU890 or TU891 as the compatible module termination units. The complete article number 3BSC690073R1 should be used for ordering.
For replacement, verify the hazardous-area design, field-device entity parameters, MTU type, channel wiring and controller configuration. Commission the module under the approved intrinsic-safety and System 800xA procedures.
