Zelio speed control relay RM35SOMW monitors underspeed and overspeed conditions,
with or without memory, with inhibition by an external contact. It operates with either N.O.
or N.C. sensors. Adjustable time between impulses is 0.05 s to 10 min. Power-on
inhibition time is adjustable from 0.6 to 60 s. Inhibition is controlled by an external
contact. Settings are protected by a sealable cover, control status is indicated by an LED,
and it is DIN rail mountable.
