KSDB SERIES
Description
The KSDB 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 (Delay-on-Break)
Input voltage must be applied before and during timing. Upon
closure of the initiate switch, the output energizes. The time
delay begins when the initiate switch is opened. The output
remains energized during timing. At the end of the time delay,
the output de-energizes. The output energizes if the initiate
switch is closed when input voltage is applied.
Reset: Reclosing the initiate switch during timing resets the time
delay. Loss of input voltage resets the time delay and output.
