Card Reader Interface Expansion Card

The Card Reader Interface Expansion Card (SE1-CRI-PCB) provides additional control for up to 2 doors. The board has a built-in dual Wiegand reader support for IN/OUT readers on the door and 2 relay outputs.

The board has 2 digital or analog inputs which are software configurable and can be used for combined door contact and egress button inputs or any detector inputs. Wiegand inputs are software programmed to have a pull-up resistors for situations where these inputs are voltage driven.
