Example: 2 Cars, 4 Floors

In this example, we need 2 reader ports - one for each elevator car reader - so are using a standard PRT-WX-DIN Controller. .

We've chosen a PRT-PX8-DIN to provide the 8 floor control outputs. While we are providing access control for 4 floors, we have 2 elevator cars, so need 8 relay outputs to control floor access.

We can control multiple elevators.
