4. Product Introduction
The ABB REC670 is a bay control IED designed for protection, control, and monitoring of different types of bays in power substations and networks. It combines control, interlocking, and multiple protection functions in one unit for medium and high voltage applications.
Field teams use these units for reliable breaker control, synchronized switching, and integration into IEC 61850 architectures. The REC670 reduces wiring and panel space while delivering fast fault clearing and comprehensive event recording. Always confirm the specific hardware configuration (TRM, IOM modules) matches your application requirements using the PCM600 tool.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No display or power LEDs | Power supply failure | ❌ Low | Measure voltage at power terminals | Verify DC supply polarity and fuses |
| Protection not picking up | CT/VT wiring or settings error | ✅ High | Check analog input values in HMI or PCM600 | Verify polarity and scaling in configuration |
| Communication loss (IEC 61850) | Network or GOOSE issue | ✅ Medium | Ping device, check Ethernet LEDs | Confirm IP settings and fiber/SFPs |
| Breaker fail to operate | Control circuit or output relay fault | ✅ High | Monitor output contact status | Test coil voltage and auxiliary contacts |
| Frequent false trips | Incorrect protection settings | ✅ Medium | Review event recorder logs | Compare settings against coordination study |
If the unit does not respond as expected, capture event logs, disturbance records, and configuration files before contacting support.
6. Frequently Asked Questions (FAQ)
Can I hot-swap this IED in a live substation? No. These devices require a proper outage and isolation. Live insertion risks damaging the unit or causing unintended operations. Plan the replacement during scheduled maintenance.
What condition are these units in? New Original / New Surplus from authorized channels. Every unit goes through visual inspection, power-on self-test, and basic I/O verification. Full test reports provided with shipment.
Is REC670 a direct replacement for older relays? It depends on the exact version and configuration. Check the hardware modules (TRM, BIM, etc.) and software version. Migration often needs updated drawings and settings conversion.
How do I configure the REC670? Use ABB PCM600 software. Take photos of existing DIP switches, terminal connections, and parameter settings before removal. Firmware and application configuration must match site requirements.
What warranty do you provide? 1-year warranty covering functional defects under normal operation. Does not cover damage from incorrect installation, overvoltage, or ESD events.
Why buy surplus instead of direct from ABB? Shorter lead times and lower cost while still getting genuine ABB hardware. Many plants keep these as critical spares for immediate availability during outages.
Any common pitfalls during installation? Double-check CT/VT polarity and grounding. Confirm all fiber connections are clean and properly seated. Test all interlocking logic in simulation mode before going live. A missed GOOSE subscription has caused more than one commissioning delay.
