The Doug Fleenor Design DMX512 125-5 Isolated Splitter / Amplifier is available in three standard configurations: 3, 5, or 11 outputs from a single DMX input. An enhanced five output splitter with protection from miswiring and lightning, and a universal power supply is also available (see model 125EE). Units with any number of inputs and outputs may be manufactured on a custom basis.
Each output is electrically isolated from the input, and every other output, by 2500 volt optical couplers. Each output has its own line driver and associated power supply.
