Description
The KRDI 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 KRDI Series is a cost effective approach for OEM applications that require small size, isolation,
reliability, and long life.
OperationOperation
OperationOperation
Operation
Upon application of input voltage, the time delay
begins. The output relay energizes during the time
delay. At the end of the time delay, the output de-
energizes and remains de-energized until input voltage
is removed.

Reset: Removing input voltage resets the time delay
and the output.
See accessory pages for
specifications.
