Time Delay Relays

Dedicated - Single Shot

TSDS SERIES

Description

TheTSDS Series is designed for more demanding commercial

and industrial applications where small size and accurate

performance are required. The factory calibration for ﬁxed

time delays is within 1% of the target time delay. The repeat

accuracy, under stable conditions, is 0.5% of the time delay. The

TSDS Series is rated to operate over an extended temperature

range. Time delays of 0.1 seconds to 1000 minutes are available.

The output is rated 1A steady and 10A inrush. The modules are

totally solid state and encapsulated to protect the electronic

circuitry. This product is suitable for many applications, including

dispensing, welding, and exposure timing.

Operation (Single Shot)

Input voltage must be applied before and during timing. Upon

momentary or maintained closure of the initiate switch, the

output energizes for a measured interval of time. At the end

of the delay, the output de-energizes. Opening or reclosing the

initiate switch during timing has no affect on the time delay.

The output will not energize if the initiate switch is closed when

input voltage is applied.

(Positive Switching)

(Negative Switching)

Reset: Reset occurs when the time delay is complete and the

initiate switch is opened. Loss of input voltage resets the time

delay and output.
