MSM SERIES
Description
The MSM Series replaces bi-metal type timing with reliable
solid-state circuitry. There are no moving parts to arc or wear.
It is a cost effective solution for OEM designers. It is available
for printed circuit board mounting or surface mounting with
a removable bracket and wire leads. The MSM Series offers
immediate reset on removal of power.
Operation (Delay-on-Make)
The time delay begins upon application of input voltage. 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.
