Rosslare 4-Door Expansion Module for AC-425/425IP, MD-D04B

The Rosslare MD-D04B is a convenient expansion module for AC-425/425IP access control panels. With a 4-reader interface, 4 supervised inputs, and 4 relay outputs (5 Amp Form-C N.O./N.C.), it easily integrates into the panel and offers end-of-line (EOL) resistor protection.

Installation of the module takes under one 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 is recognized by the AxTraxNG Server, and the MD-D04B can be programmed for access control and automation.

Advanced communication with the controller allows for firmware updates and real-time event logging, with support for full offline operation by the host panel.
