CEF50 (pick-up) and CEF50MU (drop-out) relays are adjustable electronic time-delayed relays.
The CEF50MU2 variant allows having a control source independent of the auxiliary source.
CEF50P has an adjustable output pulse duration (output will remain active for a specified time); it may be used as a pulse extender.
Available with DC or AC coils
Three different time ranges are available with time delays ranging from 0.012s to 42hours
Must be used in conjunction with a panel-mounting socket of type: F10 or F20
