Rosslare’s MD-IO84B is a plug-in expansion module for Rosslare’s AC-225x-B and AC-425x-B Access Control Panels. This I/O expansion board provides 8 Supervised Outputs with EOL (End-Of Line) resistor protection, and 4 Relay Outputs (5 Amp Form C NO/NC). Installation of the module takes under 1 minute with the tailored expansion port in the panels and auto recognize by the panel. Once it is installed and the panel is powered on, the expansion can be seen by Rosslare’s AxTraxNG™ or AxTraxPro™ server, and the MD-IO84B may be programmed for Access Control and Automation. Advanced communication with the controller, allows for Firmware update, and real-time event logging with support for full offline operation by the host panel. Rosslare’s MD-IO84B expansion board is designed with a focus on high quality and reliability and is ideal for residential and commercial applications. It is compatible with the AC-225x-B and AC-425x-B networked access control panels. The expansion board adds four relay outputs and eight supervised inputs to the access control panel. As a result, an access control panel with an easy to install and operate, the MD-IO84B expansion board features state-of-the-art supervised communications with the controller. The host access controller has complete control over the additional inputs and outputs of the MD-IO84B expansion board.
