For specific circuits applied to relays. Transistor VT is a high-speed, high
-voltage switching tube. The voltage resistance requirement of the switch tube is 5-10 times the rated voltage of the valve electromagnet. This circuit has the fastest response time
. The varistor Rv can also be replaced by the diode VD (as shown by the dotted line in the figure). However, using a diode will slow down the current attenuation of the relay (or
connector, electromagnet) and prolong the armature release time.
