Time Delay Relays

Dedicated - Retriggerable Single Shot

KRD9 SERIES

Description

The KRD9 Series microcontroller timing circuit provides

excellent repeat accuracy and stability. Cost effective approach

for OEM applications that require small size, isolation, reliability,

and long life.

Operation (Retriggerable Single Shot)

FunctionType A (Output Initially De-energized): Input

voltage must be applied prior to and during timing. When the

initiate switch is closed, (momentary or maintained) the output

energizes and the time delay starts. On completion of the delay,

the output de-energizes. The unit will time out if S1 remains in

the open or closed position for the full time delay. Reclosing

the initiate switch resets the time delay and restarts timing; the

output remains energized. The output will not energize if the

initiate switch is closed when input voltage is applied.

FunctionType B (Output Initially Energized): Upon application

of input voltage, the output energizes and the time delay starts.

At the end of the time delay, the load de-energizes. The unit will

time out if S1 remains in the open or closed position for the full

time delay. Closing (re-closing) the initiate switch resets the time

delay and restarts timing; the output remains energized.
