Description
The SC3/SC4 Series are solid-state 3 or 4 channel chasers
designed for sequential three circuit flashing of incandescent
lamp loads. Unlike electromechanical chasers, there are no
contacts to arc, wear, and eventually fail.
Operation
Sequential 3 or 4 circuit flashing of incandescent loads with
equal time delays for each load. Upon application of input
voltage, Load 1 is energized. At the end of the time delay, Load 1
de-energizes and Load 2 energizes. At the end of the time delay,
Load 2 de-energizes and Load 3 energizes. This cycle continues
until input voltage is removed. The set time delay (rate) is the
timing for the whole cycle, for all 3 loads (output contacts).
Reset: Removing input voltage resets the unit and cycle.
