Description

The KSD3 Series Digi-Timer is a cost effective approach for

ON/OFF recycling applications. The on time is equal to the

off time. An adjustment of the RT will change the time delays

of both on and off times. This 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 popular AC

and DC voltages. 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.

Operation (Recycling Flasher - ON Time First)

Upon application of input voltage, the output energizes and

the T1, ON time begins. At the end of the ON time, the output

de-energizes and the T2 OFF time begins. At the end of the

OFF time, the output energizes and the cycle repeats as long as

input voltage is applied.

Reset: Removing input voltage resets the output and time

delays, and returns the sequence to the ON time.

Operation (Recycling Flasher - OFF Time First)

Upon application of input voltage, the T2 OFF time begins. At

the end of the OFF time, the T1 ON time begins and the load

energizes. At the end of the ON time the load de-energizes, and

the cycle repeats until input voltage is removed.

Reset: Removing input voltage resets the output and time

delays and the sequence to the OFF time.
