Littelfuse, Inc. Time Delay Relays KRDI121

The KRDI121 is a time delay relay from Quarktwin Technology Ltd. designed for interval timing applications. It operates on a 12VDC input and features an onboard knob for adjustable time delays ranging from 1 to 100 seconds. The relay is compact, measuring 2 inches square, and utilizes a solid-state timing circuit that ensures repeat accuracy of ±0.5% and factory calibration tolerance of ±5%. The output is an isolated SPDT relay capable of handling up to 10A at 125VAC, making it suitable for controlling various loads. The encapsulated design protects the relay from shock, vibration, and humidity, enhancing its reliability in diverse environments. The KRDI121 is reset by removing the input voltage, which also restarts the timing cycle. This product is ideal for OEM applications requiring a reliable and compact time delay solution.
