METZ CONNECT MFRk-E12 Multifunction Time Relay 0.15-800s, 24-240V AC/DC, 1 CO 110310412230

Ten selectable timing functions in a single 17.5 mm module make the METZ CONNECT MFRk-E12 a versatile solution for control cabinet automation. With a wide time range from 0.15 seconds to 800 seconds across seven ranges and a universal supply voltage of 24–240 V AC/DC, this relay adapts to almost any application without additional components.

Overview

The MFRk-E12 is a multifunction time relay designed for DIN rail mounting. It offers ten different timing functions, including on-delay, off-delay, interval, and pulse shaping, selectable via front rotary switches. The time value and range are also set using rotary switches, allowing precise adjustment without programming. A status LED indicates the relay state and timing progress. The relay provides one changeover contact rated for 5 A at 250 V AC, suitable for controlling contactors, valves, or signalling devices.
