KD Digital Series Action 3 Icsotimer

Interval Delay Timer

Typical application of a KD3 Digital Series Interval Delay Timer is to control an externally connected relay. Upon voltage application, the output is energized and the delay begins. On adjustable units, an externally connected resistor determines the duration of the time interval. Upon completion of the delay, the output is de-energized. The timer resets when input voltage is removed.

Timing range options are either Adjustable or Fixed from .1 seconds to 10 hours. AC input voltage options are 12, 24, 120 and 240 VAC. DC voltage options are 12, 24, 48 and 110 VDC. Output current range is 20 ma. to 500 ma.
