FIELD: transport.
SUBSTANCE: invention relates to electric locomotive power circuits. Proposed control circuit comprises workstations of operator and assistant operator, operator controller with motion condition setting device, power hardware with drives and remote control system with rigid logic of functioning. Remote control system is built around logical elements. Input signals for power hardware state interlocking and relay simulator cut-in control are fed via three units of voltage input dividers with optical decoupling of the inputs of two electronic switching units. Outputs of two electronic switching units are connected to inputs of seven output electronic gates. Outputs of the first six units are connected to coils of power hardware. Outputs of the seventh unit is use to connect low-power AV motors.
EFFECT: higher reliability of electric locomotive control circuit.
