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.
