Product Introduction
ABB REL670*1.1-A31X00-F01-B1X0-C-B-KB-A-A6XO-DAN-BB-XD is a multi-functional numerical protection relay in the Relion 670 platform, engineered for feeders, transformers, and generators in industrial and utility networks. It integrates high-speed protection, measurement, control, and communication in a single IED.
This variant supports IEC 61850 Ed.2 for substation automation, including GOOSE messaging and MMS SCADA integration. It includes multi-zone distance protection, differential protection, breaker failure supervision, and generator protection functions. New Surplus units are fully tested for functional I/O, insulation resistance (500 V Megger), communication handshake, and firmware integrity, ensuring reliable field deployment.
Frequently Asked Questions
Q: Can REL670*1.1-A31X00-F01-B1X0-C-B-KB-A-A6XO-DAN-BB-XD be hot-swapped?
A: No. CT/VT circuits and relay outputs must be de-energized. Hot-swapping risks overvoltage and permanent relay damage.
Q: Is this configuration still supported?
A: Yes. Relion 670 remains supported for installed base protection schemes, though firmware verification and spare parts should be confirmed.
Q: Will I lose settings during replacement?
A: Yes. Backup parameters via PCM600 or front panel export. Document CT/VT ratios, I/O mapping, and protection curves before removal.
Q: Are these units factory-new or refurbished?
A: New Surplus. All units undergo serial verification, functional testing, insulation checks, and anti-static packaging.
