Control circuit for operation of relay

The operating circuit has the relay K1 coupled in series to a transistor V3 and a diode V5 to the supply voltage UB. In parallel is a second diode V7. The voltage is also applied to a resistor R2 in series with a Zener diode V2 and a capacitor C1 is coupled between them. The charge path of the capac...

Zusammenfassung:The operating circuit has the relay K1 coupled in series to a transistor V3 and a diode V5 to the supply voltage UB. In parallel is a second diode V7. The voltage is also applied to a resistor R2 in series with a Zener diode V2 and a capacitor C1 is coupled between them. The charge path of the capacitor is via the resistor. A FET V1 provides a control input point for connection to a microprocessor.
