Description
The KSDR Series offers independent time adjustment of
both delay periods. The KSDR Series is recommended for air
drying, automatic oiling, life testing, chemical metering, and
automatic duty cycling. 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
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.
Operation (Recycling - 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 T1 ON time.
Operation (Recycling - 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 T1, T2 begins and the load de-energizes.
This cycle repeats until input voltage is removed.
Reset: Removing input voltage resets the output and the
sequence to T2 OFF time.
