ABB REL561 1MRK002496-AC Protective Relay Module

This protective relay module serves as a critical safeguard for power distribution networks. Designed for industrial environments where electrical system stability matters, it handles overcurrent detection, earth fault monitoring, and differential protection – essentially acting as the nervous system for grid reliability.

Manufacturer	ABB
Model Number	1MRK002496-AC
Voltage Rating	220V AC
Certifications	IEC 60255, IEEE C37.118
Communication	Ethernet + RS485
Environmental Rating	IP54 Enclosure

Real-World Applications

We’ve seen this module deployed in everything from steel plant substations to offshore wind farms. Its digital signal processing handles complex fault patterns that older electromechanical relays would miss. A recent customer in the oil & gas sector mentioned how its differential protection caught a transformer insulation issue during a desert sandstorm – exactly the kind of scenario its IP54 rating was designed for.

Works seamlessly with other ABB systems like the DSQC robot controllers and Bailey INFI 90 DCS platforms. Common companion models include:

• 5SHY6545L0001 Power Modules
• 3BHB013088R0001 Drives
• PM866 Process Controllers
