MD-D04B Rosslare 4-Reader Expansion Module
The MD-D04B is a plug-in expansion module for Rosslare AC-425x-B access control panels. It adds a 4-reader interface, four supervised inputs and four Form C relay outputs to extend the controller for additional access points and automation functions.
Installed through the controller expansion port, the module is recognised by Rosslare AxTraxNG or AxTraxPro software and is intended for modular access control upgrades. Its Wiegand and Clock-and-Data reader support makes it useful where extra readers, keypad inputs and supervised I/O are needed without replacing the main controller.
