Time Delay Relays
Dedicated - Retriggerable Single Shot
TSD94110SB
Retriggerable Single-ShotTimer
Description
TheTSD94110SB retriggerable single-shot timer is designed
for a variety of appllcations. Its digital circuit provides long or
short delays with accuracy and stability over a wide voltage and
temperature range. It is the ideal timer for pulse-train monitoring
of programmable controllers, or any system requiring motion
detection.
Operation AType
Power must be applied to input at all times prior to and
during timing. Upon closure of initiate switch (momentary or
maintained) the load is energized and the time delay is started.
On completion of the delay period the load is de-energized.
Should the initiate switch be reclosed during timing, the delay
will be reset to zero and restarted.

Operation BType
LOAD
Upon application of input power, the load is energized and a
time delay is started. At the end of the time delay, the load is
de-energized. Should the initiate switch be closed or reclosed
during timing, the delay is reset to zero and restarted.
