Multifunction relays

Multifunction relays

Universally usable - maximum function in minimum width

Multifunctional relays are universally usable thanks to the selection of the corresponding function. They also belong to the group of time relays with which you can cost-effectively realised specific time functions. A multifunctional relay can be used as a flasher relay, clock, impulse former, start-up and/or shut-down relay as well as contact and recurrence delay. You can simply set the respective function on the device.
