Realize local & remote control for breakers, disconnectors and earthing switches at bay level. Built‑in select‑before‑operate logic, bay‑level and station‑wide interlock function. Collect binary input signals, monitor trip‑circuit condition and equipment status. Complete analog measurement of voltage, current, power and frequency. Support event sequence recording, fault disturbance recording and parameter management. Exchange data with station control system via multiple communication protocols. Comprehensive hardware self‑diagnosis, detect module faults and upload alarm information. Configuration and maintenance are performed via PCM600 engineering tool.
Difference compared with 1MRK008514‑AA: 1MRK008514‑AB is revised hardware variant; mechanical dimension and mounting are fully compatible with AA version, can be physical drop‑in replacement; optimizes EMC circuit and component selection for better anti‑interference capability, software project needs re‑verification after replacement.
Install in 19‑inch standard rack inside substation control cabinet. Standard secondary wiring for binary input and output loops. Auxiliary power supply shall be within rated voltage range. After unit replacement, download complete project configuration file, verify interlock logic, switch control function, point‑to‑point signal test and station‑control communication. Check self‑diagnosis status to confirm no hardware fault alarms.
Bay‑level control for power plant and high‑voltage substation, suitable for feeder bay, transformer bay and bus‑coupler bay. Used for switchgear operation control, status acquisition and data uploading in power grid and industrial power distribution secondary protection systems.
- Relion 650 series revised‑version bay‑level control unit for substation bay‑control application.
- Draw‑out modular hardware, physical drop‑in compatible with former AA version, convenient for on‑site maintenance replacement.
- Optimized EMC performance, strong anti‑interference capability for substation secondary environment.
- Powerful interlock logic, select‑before‑operate mechanism to prevent mis‑operation.
- Native IEC 61850 and GOOSE support, adapts to digital substation construction requirements.
- Integrated measurement, event recording and disturbance recording functions, no extra auxiliary equipment required.
- Industrial spare‑part for maintenance and retrofitting of legacy ABB Relion 650‑series bay‑control devices.
