Access Add-on 2 door plugin PCB for expansion of door capacity

The MD- I084 is an optional expansion board for use with Rosslares state-of-the-art family of networked access controllers, specifically the AC -225 and AC-425 models.

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 Rosslares access control software system. The software system also configures the MD-IO84s input connection topology.

Features

• 8 supervised, 4-state, dual EOL inputs input relays
• 4 fully programmable 5A Form-C relay outputs
• Optional expansion for AC-225, AC-425
