The MD- I084 is an optional expansion board for use with Rosslare’s state-of-the-art family of networked access controllers, specifically for the AC -225 .

The expansion board adds an additional four relay outputs and eight supervised inputs to the access control panel.

The host access controller has complete control over the additional inputs and outputs of the MD-IO84 expansion board. The inputs and outputs can be configured using Rosslare’s access control software system. The software system also configures the MD-IO84′s input connection topology.
