FIELD: elevator equipment.
SUBSTANCE: elevator controller comprises a safety control circuit, a safety brake circuit and/or a safe torque off circuit. Safety control circuit input terminal is connected to elevator safety circuit. Output terminal of the safety control circuit is connected to the input terminal of the safety brake circuit and/or the safe torque off circuit. Safety control circuit converts high-voltage electric signal from elevator safety circuit to power signal or control signal required for safety brake circuit and/or safe torque off circuit. Elevator comprises elevator safety circuit and elevator controller. Elevator safety circuit comprises several switches, and input terminal of elevator safety circuit is connected to high-voltage electric signal. Output terminal of the elevator safety circuit is connected to the input terminal of the safety control circuit.
EFFECT: reduced frequency of elevator failures.
