Time Delay Relays

Dedicated - Recycle

KRDR SERIES

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 - ONTime First)

Upon application of input voltage, the output relay energizes and

theT2 ON time begins. At the end of the ON time, the output

de-energizes and theT1 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 - OFFTime First)

Upon application of input voltage, theT1 OFF time begins. At

the end of the OFF time, theT2 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.
