NMTCV Delayed ON Timer
Electronic relay whose output contact connects with a certain adjustable delay from
the moment voltage is applied to supply terminals A1-A2. It has four timing ranges:
see drawing. Range selection is made by dip-switches located on the front of the relay.
Times are set by front potentiometer controlling an Application Specific Integrated
Circuit (ASIC) specially designed for this group of relays. This allows for excellent
precision and repeatability features.

NMETV Star-Delta Starter Timer
Electronic relay timed in steps whose purpose is to control star-delta starting. When
supply voltage is applied to the A1-A2 terminals, the star contact (17-18) closes for an
adjustable time between 6 and 60 sec. (selectable). When this time is up, it opens, there is
a pause and then the delta contact connects (17-18). The standard pause time is about
100ms. Times are set by front potentiometer controlling an ASIC specially designed for
this group of relays. This allows for excellent precision and repeatability features.

NMRDV Delayed OFF Timer
Electronic relay whose output contact instantly connects when supply voltage is applied
to terminals A1-A2. It disconnects with an adjustable delay from the moment the relay
loses supply voltage.There are several types depending on the range of timers. There are

NMTDV Delayed OFF Through Contact Timer
Electronic relay whose output contact connects instantly when connecting the Y1-Y2
terminals with a voltage-free control. It disconnects with an adjustable delay when the
terminals are disconnected. The relay must be supplied with nominal voltage between
A1-A2. Loss of supply voltage causes immediate disconnection. It has timing ranges:
see drawing. Range selection is made by dip-switches located on the front of the relay. Times
are set by front potentiometer controlling an ASIC specially designed for this group of relays.
This allows for excellent precision and repeatability features.
