How many floors of elevators can be controlled by your MC-5816A? What should I do if I have 38 floors of elevators?

Hello! Thanks for using our company's products! Our company's MC-5816A single access controller supports 16 management, and can also be expanded through the extended board, it supports up to 3 16-channel extended boards, and finally can manage up to 64 floors. You need to manage the 38th floor elevator, it is recommended to purchase one MC-5816A, and then purchase two extended boards to use together.
