Electronic control lock drive circuit

Electronically controlled magnesium drive circuit: The electronically controlled lock drive circuit is shown in Figure 27<7. After the user swipes the card, the main control device receives the card reader information, decodes the
Manchester code, obtains the 5-byte card number, and determines the validity of the card number. If the card number is legal, the door is allowed to be opened, and the Control Lock terminal is

low power. level, the photoelectric isolator works, the transistor driving the relay is turned on, the relay coil is energized, and the electric lock is opened . When the Control Lock terminal is
high level, the relay is powered off and the electric lock is closed.
