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.

Function
Function Type 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 deenergizes. 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.
Function Type 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.
Reset: The time delay and the output are reset when
input voltage is removed.
