TDR SERIES
Relay Output, Recycling Time Delay Relay
Description
The TDR Series of time-delay relays are comprised of digital
circuitry and an isolated, 10A 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 to be precise every time.
Operation (Recycling - ON Time First)
Upon application of input voltage, the green LED glows, the
output relay is energized, the red LED glows, and the T1 ON
time begins. At the end of the ON time, the output
de-energizes, the red LED turns OFF and the T2, OFF time
begins. At the end of the OFF time, the output relay energizes
and the cycle repeats as long as input voltage is applied.
8-PIN
Reset: Removing input voltage resets the output and time
delays, and returns the sequence to the first delay.
Operation (Recycling - OFF Time First)
Upon application of input voltage, the green LED glows, the T1
OFF time begins, the load is OFF. At the end of the OFF time,
the T2 ON time begins, the load energizes, and the red LED
glows. At the end of the ON time the load de-energizes and
the red LED turns OFF. The cycle repeats until input voltage
is removed.

Reset: Removing input voltage resets the output and the
sequence to the OFF time.
