For Advant 800xA system applications, ABB DI890 provides the function of a Digital Input.
For replacement planning, this class of module brings discrete field status into the control system. Typical signal sources include switches, relay contacts, permissives, and equipment-status circuits when they match the module's electrical requirements. The original wiring and configuration records should guide application.
ABB Advant and System 800xA environments combine control, I/O, communication, and operator resources. This product supports the hardware function identified by its description within the installed system. Selection should account for the intended surrounding hardware configuration.
Country of origin is listed as Singapore.
In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Exact operating details should be taken from the installed model documentation.
