Description
The TAC1 Series was designed to delay the operation of a
compressor relay. It eliminates the possibility of relay chatter
due to half-wave failure of the output. It connects in series with
the load relay coil and provides a delay-on-make time delay
each time input voltage is applied. It can be used for random
start, anti-short cycling, sequencing, and many other
applications. It is an excellent choice for all air conditioning and
refrigeration equipment.
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.
