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.
