5. Circuit‑breaker failure protection 50BF, pole‑discrepancy protection
6. Over‑voltage / Under‑voltage 59/27, frequency protection 81, out‑of‑step protection
7. Auto‑reclosing 79, fault locator, broken‑conductor detection

Monitoring & Recording

• COMTRADE format disturbance recorder, Sequence of Event Recorder (SER)
• Circuit‑breaker condition monitoring, trip‑circuit supervision
• Electrical measurement, fault location function

Compatibility Notes

1. Exact part number 1MRK002133‑ABR02, hardware revision ABR02. Compatible with Relion 650 / 670 family IEDs (RED670, REF670, RET670, REB670) in I/O extension racks; NOT compatible with 615/620/630 series devices.
2. Verify hardware revision for replacement. Different hardware revisions are not freely interchangeable; channel test required after replacement.
3. RED670 firmware version must match project configuration files.
4. This board provides only output I/O functions; protection logic resides on CPU main board.

Procurement Notes

• Distinguish full IED RED670 versus I/O board 1MRK002133‑ABR02. 1MRK002133‑ABR02 is merely output board, not complete protection relay.
• Confirm full part number and hardware revision for spare parts; inspect backplane connector and relay contact condition.
