METZ CONNECT monitoimiaikarele MFRk E08 230VAC/24VUC 1WE 30h 110658

Industrial and building automation often requires precise timing control for processes such as delayed start-up, interval switching, or flashing signals. The METZ CONNECT Multifunction Time Relay MFRk E08 solves these challenges by combining eight timing functions and seven time ranges in a single compact DIN rail module. With a wide supply voltage range of 230 V AC or 24 V UC (AC/DC), it adapts to various control circuits, while the SPDT changeover contact handles loads up to 5 A. The relay's LED indicators provide clear status feedback, and screw terminals ensure secure wiring. Whether you need an ON-delay, OFF-delay, flasher, or pulse former, this relay offers flexible configuration for diverse applications.

Who is it for

This time relay is ideal for electricians, panel builders, and maintenance technicians working in industrial control systems, HVAC, lighting control, and building automation. It suits applications requiring reliable timing functions with adjustable delays from 0.05 seconds to 30 hours. The dual voltage capability makes it versatile for both AC and DC control circuits, and the DIN rail mounting simplifies installation in distribution boards and control cabinets.

Tips

When setting the time range, ensure the selected range covers the desired delay to avoid inaccuracies. For DC operation, observe polarity if required. Use appropriate wire end ferrules for reliable screw terminal connections. Mount the relay on a standard 35 mm DIN rail in a well-ventilated enclosure to maintain operating temperature limits. Test the timing function after installation to verify correct operation.
