Model Overview: AIM0006 (Part Number: 2RCA021397A0001P)

The ABB AIM0006 (Ordering Part Number: 2RCA021397A0001P) is a specialized Analog & Binary Analog Interface Module designed for ABB numerical protection relays and power control I/O units.

Serving as an input signal acquisition and processing board, the AIM0006 module measures AC voltage feedback and senses discrete field contact status. The module configuration “5U + 4BI” indicates that it provides 5 voltage measurement channels (5U) and 4 discrete binary inputs (4BI). It converts analog transformer signals and contact closures into isolated digital signals for the main relay processor.
