Time Delay Relays

Dedicated - Single Shot

KRDS SERIES

Single Shot

Description

The KRDS Series is a compact time delay relay measuring only

2 in. (50.8 mm) square. Its microcontroller timing circuit provides

excellent repeat accuracy and stability. Encapsulation protects

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

effective approach for OEM applications that require small size,

isolation, reliability, and long life.

Operation (Single Shot)

Input voltage must be applied before and during timing. Upon

momentary or maintained closure of the initiate switch, the

output relay energizes for a measured interval of time. At the

end of the delay, the output de-energizes. Opening or reclosing

the initiate switch during timing has no affect on the time delay.

The output will energize if the initiate switch is closed when

input voltage is applied.

Reset: Reset occurs when the time delay is complete and the

initiate switch is opened. Loss of input voltage resets the time

delay and output.
