TMV8000 / TSU2000 SERIES
Description
The TMV and TSU Series are universal voltage delay-on-make
timers. Two models cover all the popular voltages and time
delays. Available with knob or external adjust time delay. Its
simple two terminals can easily be connected in series with a
relay coil, contactor coil, solenoid, lamps, small motor, etc., to
delay their energization, prevent short cycling or to sequence on
various loads.
Operation (Delay-on-Make)
Upon application of input voltage, the time delay begins. The
output is de-energized before and during the time delay. At
the end of the time delay, the output energizes and remains
energized until input voltage is removed.
Reset: Removing input voltage resets the time delay and output.
