ABB designates AI931N as an Analog Input Module associated with the Advant 800xA control platform.
In day-to-day system operation, 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. Final selection should be based on the plant's controlled-equipment records.
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. Exact operating details should be taken from the installed model documentation.
For ongoing lifecycle support, proper application depends on matching the product to the original control-system design, including its physical position, electrical connections, and configured relationship with surrounding hardware. The plant's maintenance records should support final product selection.
