FIELD: electricity.
SUBSTANCE: device contains decoupling units of digital signals and supply voltage in combined line of supply and data exchange in on-board system of electric equipment fed by generator or accumulator. Devices of galvanic isolation of line, current limiters in line, voltage limiters between line wires, between line and machine mass, generator output voltage, supply voltage of component of electric equipment system or any combination of these protection devices are used in the device additionally. Supply voltage delivered by line may be constant or alternating. In the last case, the device contains adequate voltage converter and, if necessary, rectifiers in end points of line. Decoupling units of digital signals and supply voltage are made based on optoelectronic devices, capacitors or signal transformers, and device of galvanic isolation is made in the form of insulating voltage converters.
EFFECT: improving reliability of transfer of supply voltage and data signals upon load increase in the system.
