Embodiment Construction
[0011] 1. Control signal
[0012] Such as figure 2 As shown, the effective signal of the control terminal Ctr1 is a level signal (the circuit is active at high level), and the effective signal of the control terminal Ctr1 is a signal with adjustable pulse width. When both the control terminal Ctr1 and the control terminal Ctr2 are valid signals, the relay coil is connected to both ends of the power supply to generate a driving current, and the relay operates.
[0013] 2. Conversion circuit
[0014] Such as figure 2 As shown, the level signal of the control terminal Ctr1 is connected to the base of the triode Q2 through the current limiting resistor R3, and the conduction between the input terminal of the optocoupler U1 and the power supply vcc is controlled by a meter; the pulse width adjustable square wave signal of the control terminal Ctr2 is limited The current resistor R1 and the DC blocking capacitor C1 are filtered by the capacitor C2 and then converted into a leve...
