KRDB SERIES

2019-05-23
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.

Operation (Delay-on-Break)

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: Reclosing the initiate switch during timing resets the time

delay. Loss of input voltage resets the time delay and output.
