Elevator IC card floor expansion board

Expandability: Up to 4 floor expansion boards can be connected to one controller, allowing up to 64 floors to be controlled. This expansion method is flexible and convenient, without any additional settings, and the system adapts automatically.
Connection: The floor expansion board is connected by passive dry contact, which is completely isolated from the original elevator system and will not have any impact on the original performance of the elevator. When the fire signal input or control system is powered off, the elevator IC card access control system will automatically disconnect, and the elevator will resume normal use for ordinary elevators.
Power requirements: The elevator access control motherboard usually uses a professional-grade 12V/5A elevator power supply, with a unique U–sense function, which can realize the reset of the starting layer.
