The KRDI Series is a compact time‑delay relay measuring only 2 in. (50.8 mm) square. Its solidstate 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.
Operation (Interval): 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.
