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.

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.
