Description

The KRDR Series is a compact time-delay relay measuring only

2 in. (50.8 mm) square. Its solid-state timing circuit provides

excellent repeat accuracy and stability. Encapsulation protects

against shock, vibration, and humidity. The KRDR Series is a cost

effective recycling timer for OEM applications that require small

size, isolation, reliability, and long life.

Operation (Recycling - ON Time First)

Upon application of input voltage, the output relay energizes and

the T2 ON time begins. At the end of the ON time, the output

de-energizes and the T1 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 the time

delays, and returns the sequence to the ON time.

Operation (Recycling - OFF Time First)

Upon application of input voltage, the T1 OFF time begins. At

the end of the OFF time, the T2 ON time begins and the load

energizes. At the end of the ON time the load de-energizes, and

the cycle repeats until input voltage is removed.

Reset: Removing input voltage resets the output and the

sequence to the OFF time.
