Irrigation motor automatic protector circuit diagram 1
The irrigation motor automatic protector circuit is composed of the power supply circuit and the detection / protection control circuit, and the circuit is shown as the figure. Power supply circuit is composed of the power transformer T, rectifier diodes VD1 ~ VD4 and filter capacitor C1. Detection / protection circuit is composed of the detection electrodes A, B, Start button S, resistors R1 ~ R4, capacitor C2, optocoupler VLC, bi-directional trigger diode V, thyristor VT, electronic switch IC IC and AC contactor KM. AC 380V voltage is bucked by T, rectified by VDI ~ VD4 and filtered by C1 to provide 9V DC voltage for the electronic switch IC IC. RI ~ RZI select l/4W metal film resistors.
