The Cebek LS-4 is a 4-Channel sequencer. The LS-4 uses MOSFET transistors to alternate between the four outputs (One after each other). This module has the unique facility which allows you to select the number of channels. (2, 3 or 4) The speed is adjustable between by means of a PCB mounted pre-set potentiometer, 0.2 to 12 seconds. The outputs can each control a 12Vdc load up to 2 Amps, a red LED gives on board indication of transistor output. Ideal for switching LED Tape, Incandescent lamps or even relays.
