KSD4 SeriesTimer - Delay-on-Make
Connection:
L1 N/L2
The KSD4 Digi-Timer offers a delay-on-make
function with normally closed solid-state output.
The load is energized prior to and during the time
delay. 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 xed 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.
Operation (Delay-on-Make NC):
Upon application of input voltage, the load energizes
immediately. When the initiate switch is closed, the time
delay begins. At the end of the time delay, the load de-
energizes.
Reset: When the initiate switch is reopened, the load
energizes and the time delay is reset. Removing input
voltage resets the time delay.
