Time Delay Relays Dedicated - Interval KSD2 SERIES Interval Timer Description The KSD2 Series is designed for general purpose commercial and industrial applications where a small, cost effective, reliable, solid-state timer is required. The factory calibration for fixed time delays is within 5% of the target time delay. The repeat accuracy, under stable conditions, is 0.5% of the selected time delay. This series is designed for input voltages of 24, 120 or 230VAC. Time delays of 0.1 seconds to 1000 minutes are available in 6 ranges. The output is rated 1A steady and 10A inrush. The modules are totally solid state and encapsulated to protect the electronic circuitry. An excellent choice for most OEM pulse shaping, maximum run time, and other process control applications. Operation (Interval) Upon application of input voltage, the time delay begins. The output 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.

Humidity 95% relative, non-condensing The time delay is adjustable over the time delay range selected by varying the resistance across the R terminals as the resistance increases the tie T Weight 2.4 oz (68 g) delay increases. When selecting an external R , add the tolerances of the timer and the R T T for the full time range adjustment. Examples: 1 to 50 S adjustable time delay, select time delay range 1 and a 50 K ohn R . For 1 to 100 S use a 100 K ohm R .
