The KRDS221 is a time delay relay from Quarktwin Technology Ltd. designed for single shot applications. It operates on an input voltage of 24VAC/DC and features an onboard adjustable time delay ranging from 1 to 100 seconds. The relay is compact, measuring 2 inches square, and utilizes a microcontroller-based timing circuit that offers 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 AC or DC loads. The device is encapsulated to protect against environmental factors such as shock, vibration, and humidity. Reset occurs upon completion of the time delay or loss of input voltage. The KRDS221 is suitable for OEM applications requiring reliability and compact design.
