Product Overview
The 1MRK002133-ABr03 is a pluggable binary output module designed for ABB Relion 670 series protection and control IEDs. It provides multiple isolated relay outputs to issue breaker trip/close orders, alarm signals and interlock control commands to switchgear and auxiliary devices. Galvanic isolation isolates internal IED logic circuits from external field wiring, preventing damage caused by switching surges and ground potential differences in substation environments. Protection engineers and substation maintenance staff adopt this module to expand the output capacity of feeder, transformer and busbar protection relays. Stable contact performance guarantees reliable protection action upon power system faults.
Application Scenarios
- HV/MV Substation Bay Control IEDs: Sends trip commands to circuit breakers and transmits fault alarm signals to local annunciators and SCADA systems.
- Power Transformer Protection Systems: Executes transformer trip logic and drives auxiliary alarms for overheating, oil pressure and other abnormal conditions.
- Wind & Solar Farm Grid Connection Switchgear: Controls grid interlocking equipment and reports fault status to central monitoring systems.
- Industrial Medium Voltage Distribution Protection: Extends output channels for motor protection, busbar protection and safety interlock control.
