4. Product Introduction
The ABB 1MRK000005-380 is a relay output card for the Relion 670 series Intelligent Electronic Devices (IEDs), commonly used in REG670 generator protection relays. It plugs into the IED chassis to expand binary output capability for breaker tripping, alarm signaling, or interlocking in generator, transformer, or line applications.
This card delivers reliable, isolated contacts that handle high inductive loads typical in substation environments. Field teams replace it during maintenance or failures in existing 670 series racks because it matches original pinouts and firmware—no config changes or re-testing required beyond basic output forcing.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No output activation (relay doesn’t click) | No command from IED logic or card fault | ✅ High | Force output in PCM600; listen/measure contact continuity | Verify IED config; test with multimeter |
| Contacts stuck open/closed | Welded contacts from overload | ✅ High | Measure resistance across terminals; cycle output | Replace card; check load rating exceeded |
| Intermittent tripping | Loose insertion or vibration | ✅ High | Reseat card; check chassis mounting | Secure card; inspect for corrosion |
| Output LED off despite command | Power/comm issue to card | ✅ Medium | Check IED diagnostics for module status | Reload IED config; swap card position |
| High contact resistance | Arcing/wear from frequent ops | ✅ Medium | Measure closed resistance (<50 mΩ typical) | Replace if >100 mΩ; reduce cycle rate |
| No isolation (ground faults) | Internal breakdown | ✅ High | Megger test isolation (>1 MΩ at 500 V) | Replace card immediately |
| IED reports output fault | Card self-test fail | ✅ High | Read IED event/fault logs in PCM600 | Isolate to output card; replace |
670 series output cards fail from overload, age-related contact wear, or vibration—not randomly. Always force outputs in PCM600 and measure externally first. Grab IED logs, LED states, and contact resistance readings. Send details if it’s not responding; we can pinpoint fast.

6. Frequently Asked Questions (FAQ)
What is the 1MRK000005-380 used for in REG670? It’s a plug-in binary output relay card that adds isolated contacts for tripping breakers, signaling alarms, or control functions. REG670 uses multiple such cards depending on config (e.g., A20/B30/C30) for generator protection outputs.
Is this card still manufactured new by ABB/Hitachi Energy? No, Relion 670 series components like this are mature/obsolete. We stock new surplus—unused, sealed or new-old-stock from spares kits. They perform identically to originals but without active manufacturer warranty.
How many outputs does it have? Typical 8–16 relay contacts (NO/NC configurable per application). Exact count depends on variant—check your REG670 hardware config or photos for labeling (often “Relay Card 614”).
Can I hot-swap this card? No—power down the IED first to avoid faults or damage. 670 series isn’t hot-swappable for I/O cards. Plan outage; outputs are non-critical during swap if redundant.
Will swapping lose IED configuration? No—configs and settings live in the main CPU/NUM module. Swap the card, power up—the IED recognizes it and uses existing output mapping. Force-test outputs post-swap to confirm.
Why surplus over refurbished cards? Surplus units have no field cycles—no contact arcing, no thermal stress, no contamination. Refurbs often from failed IEDs with worn relays. We test every 1MRK000005-380: insertion check, contact continuity, isolation test, and cycle simulation.
What warranty do you offer? 1-year functional when installed per 670 series manual. Covers defects, not overload, arcing damage, or improper handling. Test reports with photos, continuity data, and basic cycle verification available on request.
