Alternating Relay and Time Relay E1ZMLA10 24–240V AC/DC – Pump Alternator with Integrated Timing Functions
The E1ZMLA10 24–240V AC/DC from TELE combines an alternating relay, pump alternator, and time relay in one compact device. It was specially developed for applications where two pumps, motors, or loads are to be used equally to reduce wear and increase operational reliability.
The relay has five selectable functions: Alternating Relay (Pump Changer), On-Delay, Off-Delay, Manual ON, and Manual OFF. In alternating relay mode, two loads are controlled alternately, ensuring an even distribution of operating time.
Seven adjustable time ranges from 50 ms to 100 hours allow for flexible adaptation to a wide variety of control tasks. The universal supply voltage range of 24 to 240V AC/DC reduces inventory effort and allows for use in almost all industrial applications.
LED indicators show the supply voltage, time elapsed, and relay status. Thanks to its narrow width of only 17.5 mm, the device can be mounted on DIN rails to save space and is ideal for pump controls, water technology, building automation, and industrial plants.
