Interval (Impulse ON) KRDI Digi-Timer Time Delay Relay 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. Operation Compact Time Delay Relay Full 10 A SPDT Output Contacts Onboard or External Adjust or Fixed Delay Delays from 100 ms...100 m in 5 Ranges +/-0.5% Repeat Accuracy +/-5% Factory Calibration Input Voltages from 12 ... 120 V in 4 Ranges Function 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 deenergizes and remains de-energized until input voltage is removed. Reset: Removing input voltage resets the time delay and the output.
