Time Delay Relays
Dedicated - Interval
KSD2 SERIES
IntervalTimer
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.
