osed of an operational amplifier connected to the inverting input of the amplifier so that the inverted voltage 1/2Us. You can use potentiometer sensitivity adjustment switch within 10 to 10 the fourth lx range. Decided to switch resistors Rh size of hysteresis loops. The output circuit is controlled by the contactor coil.
