ABB 1MRK002122-ABR02 Relion 615 Binary I/O Module

The ABB 1MRK002122-ABR02 Relion 615 Binary I/O Module is a plug-in binary I/O module of the ABB Relion 615 series protection and control IEDs, providing binary input/output interfacing for relay configurations that require additional digital I/O beyond the base unit. It belongs to the 1MRK002122-xxx plug-in module family — the same family that includes the -ABR01 binary I/O module and the -ABr03 optical short-range line data communication module.

1. Verify the exact variant (-ABR01/-ABR02/-ABr03…) and its function against the Relion 615 ordering documentation — sibling codes differ in function.
2. De-energize the IED and disconnect auxiliary supply before inserting or removing the module; follow ESD precautions.
3. Insert the module into the designated slot of the IED; seat and latch it fully.
4. Wire the binary inputs/outputs per the IED connection diagram, observing polarity and voltage class (24 V DC).
5. After power-up, verify I/O status and configuration via the IED front panel / PCM600 before returning the protection to service.
