Reversible magnetic starter of general power-driven multi-turn execution mechanism

The invention relates to a reversible magnetic starter of a power-driven multi-turn execution mechanism. A display unit comprises a touch screen; an operating unit comprises a test/ working mode selection switch, the touch screen and a change-over switch; a signal acquisition unit comprises a signal processing board and an analog-digital conversion module; and the units are connected with a programmable controller of a control unit respectively. The reversible magnetic starter is high in reliability and strong in anti-interference capacity, is used for controlling local/ remote places, start, closure, stop, self protection/ instantaneous release, travel limit, torque limit and the like of the power-driven multi-turn execution mechanism, and carries out comprehensive protection on turn-on of a contact of a contactor, current overload, current short circuit, default phase, under-voltage, earth leakage latching resistance and the like in real time; and the touch screen displays working conditions or fault types
