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. Technical Data Operation Sequential 3 circuit flashing of incandescent lamp loads. Fixed rate. For sequential 4 circuit and adjustable rates, please contact the factory Rate Fixed: 30 operations per minute (±10%) Input Voltage 120VAC ±15% AC Line Frequency 50/60 Hz Output Type Solid state Rating 1A steady state per output Mechanical Mounting Surface mount with two #6 (M3.5 x 0.6) screws Dimensions H 88.9 mm (3.5”); W 63.5 mm (2.5”);D 31 mm (1.22”) Termination 0.25 in.
