FS100 SERIES
Low Current Flasher
Description
The FS100 Series (low current) may be used to control inductive,
incandescent or resistive loads. This series offers a 1A (fullwave)
or a 2A (halfwave) steady state, 10A inrush solid-state output
and may be ordered with an input voltage of 24 or 120VAC. The
FS100 Series offers a factory fixed flash rate of 75 FPM or may
be ordered with a fixed, custom flash rate ranging from 45 to
150 FPM. Ideal for OEM applications where cost is a factor.
Operation
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.
