12-volt access control and 24-volt Panasonic automatic door machine wiring
1, the general automatic door has an interface provided to the access control. 2, if not the best way is to control the automatic door of the infrared sensor
Access control provides a set of 12V power supply, access control output 12V relay, and then use a passive contact to control the automatic door open the door.
Buy a DC-DC buck module, the 24V power supply down to 12V access access control, output or relay isolation, to prevent access control and door controller because of mutual interference.
12 volt access to the current you first find, and then borrow one of the open signal points to control the 24V Panasonic automatic door machine system. This may need to be modified according to the situation to install the circuit. Plus a 12V miniature relay can be used. I have transformed a similar system.
