It connects directly to the controller through the expansion ports on the controller. It has 8 relay outputs (potential free contact/powered output), 8 programmable digital inputs and 8 multi-purpose I/O points. The multi-purpose I/O points can be assigned as 8 additional inputs, OR 8 additional outputs. When configured as an output, they are potential free contacts. When wired through a relay, they can be used to drive a higher current device (like a magnetic lock), alternatively they can switch LEDs on mimic panels or other low-current devices.
