Time Delay Relays

Dedicated - Delay-on-Make

KRDM SERIES

Description

The KRDM 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 KRDM Series is a

cost effective approach for OEM applications that require small

size, isolation, reliability, and long life.

Operation (Delay-on-Make)

Upon application of input voltage, the time delay begins. The

output is de-energized before and during the time delay. At the

end of the time delay, the output relay energizes and remains

energized until input voltage is removed.

Reset: Removing input voltage resets the time delay and output.
