Time Delay Relays
Dedicated - Recycle
TSDR SERIES
Description
The TSDR Series is an ON/OFF or OFF/ON recycling timing
module designed to control metering pumps, chemical valves,
flash lamps, or use in energy saving or duty cycling applications.
The TSDR 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 < ±5%. The repeat accuracy, under stable conditions,
is 0.5% of the time delay. The TSDR 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.

Operation (Recycling - ON Time First)
Upon application of input voltage, the output energizes and
the T1, ON time begins. At the end of the ON time, the output
de-energizes and the T2, OFF time begins. At the end of the
OFF time, the output energizes and the cycle repeats as long as
input voltage is applied.
Reset:
Removing input voltage resets the output and time
delays, and returns the sequence to the T1 ON time.
Operation (Recycling - OFF Time First)
Upon application of input voltage, the T2 OFF time begins. At
the end of the OFF time, the T1 ON time begins and the load
energizes. At the end of the T1, T2 begins and the load
de-energizes. This cycle repeats until input voltage is removed.
Reset:
Removing input voltage resets the output and the
sequence to T2 OFF time.

External Resistance vs. Time Delay
This chart applies to externally adjustable part numbers.
The time delay is adjustable over the time delay range selected by varying
the resistance across the R
T
terminals; as the resistance increases the tie
delay increases.
When selecting an external R
T
, add the tolerances of the timer and the R
T
for the full time range adjustment.
Examples:
1 to 50 S adjustable time delay, select time delay range 1 and
a 50 K ohn R
T
. For 1 to 100 S use a 100 K ohm R
T
.
