Description
The KRDB 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 KRDB Series is a cost effective approach for OEM applications that require small size,
isolation, reliability, and long life.
OperationOperation
OperationOperation
Operation
Input voltage must be applied before and during
timing. Upon closure of the initiate switch, the output
relay energizes. The time delay begins when the initiate
switch is opened. The output remains energized
during timing. At the end of the time delay, the output
de-energizes. The output will energize if the initiate
switch is closed when input voltage is applied.
Reset: Reset:
Reset: Reset:
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time
delay and output.
See accessory pages for
specifications.
