DescriptionDescription
The TDR Series of time delay relays are comprised of digital circuitry and a 10 A isolated relay output. The ON
and OFF delays are selected by means of two ten position binary switches, which allow the setting of the
desired delay the first time and every time.
Switch Settable Time Delays Both Times Adjustable

Upon application of input voltage, the output relay is
energized 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
relay is energized and the cycle repeats as long as
input voltage is applied. The OFF time may be the first
delay in some recycling timers.
