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.
