Eltako MFZ12DX-230V Multifunction Time Relay 230 V AC 10 Functions 0.1 s - 4 h DIN Rail 23001007

Unlike conventional time relays that lock you into a single function, the Eltako MFZ12DX-230V puts ten selectable timing modes behind one DIN-rail module. From fleeting 0.1-second pulses to four-hour delays, it adapts to control cabinets, stairwell lighting, ventilation, and industrial sequencing without swapping hardware. The potential-free changeover contact handles up to 10 A resistive loads, while the wide 230 V AC coil accepts 50 or 60 Hz mains directly.

Highlights

• 10 selectable functions: on-delay, off-delay, pulse, flasher, and more
• Wide time range: 0.1 s to 14,400 s (4 h) via front dial
• 1 changeover contact (SPDT) with AgSnO2 contacts for long life
• 10 A / 250 V AC switching capacity, 100 mW minimum load
• Compact 1 TE (18 mm) DIN rail housing, screw terminals
• IP20 protection, -20 °C to +50 °C operating range

In daily use

Set the function and time with the clearly marked rotary selectors, then watch the LED indicate relay state. Standby draw is only 0.8 W, rising to about 4 W when active. The relay is designed for control panels where space is tight but reliability is non-negotiable: the contact material resists welding and the mechanical life reaches 10 million operations. For machine builders and electricians, the MFZ12DX-230V means one stock item covers many timing tasks.
