ABB REC670 Bay Control IED Unit

Module Feature

REC670 is the bay control IED within ABB Relion 670 series.

It integrates bay-level control, switching interlock, electrical measurement and multi-type protection functions for power substation switchgear bays. It supports dual Ethernet, GOOSE messaging and IEC61850 process bus, equipped with local HMI for on-site operation and status check. It is widely deployed in transmission and distribution substations for breaker control, voltage monitoring and interlock logic.

Working principle

The IED collects CT/PT analog signals and field switch contact status.

It executes protection algorithms and bay interlock logic, outputs trip or close commands to circuit breakers. Event data, measured values and alarm logs are uploaded to SCADA system via IEC61850 communication. It provides fast GOOSE signal exchange between substation IEDs.

Onboard components

Main CPU board, analog acquisition module, binary input/output module, HMI display panel, Ethernet communication circuit, power supply unit.

LED indicators

Front LEDs show power, run status, alarm, trip and communication link status.

Hardware self‑diagnosis

Continuous self-test detects power failure, module fault, signal circuit anomaly and communication interruption, event records are stored locally.

Programming software

PCM600, used for IED configuration, protection setting, signal mapping and disturbance record analysis.
