1 / 1
Description
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 or 4 loads (output contacts). Reset: Removing input voltage resets the unit and cycle.- Part Number
