TS441165

Description

The TS441165 is an analog delay-on-make timer with a normally

closed solid-state output. Unlike an interval timer, the load is

energized prior to and during the time delay period. It can be

used as a faster starting interval time delay when S1 is closed

upon application of input voltage.

Operation (Delay-on-Make NC)

Upon application of input voltage, the load is energized

immediately. When the initiate switch is closed, the time delay

begins. At the end of the time delay, the load de-energizes.

Reset: When the initiate switch is reopened, the load again

energizes and the time delay is reset. Removing input voltage

resets the time delay and output.
