4 Reader Expansion Board
Rosslare’s MD-D04B is a plug-in expansion module for Rosslare’s AC-425x-B access control panels that provides a 4-reader interface, four supervised inputs with end-of-line (EOL) resistor protection, and four relay outputs (5 Amp Form-C N.O./N.C.) to the panel. Installation of the module takes under one minute with the tailored expansion port in the panels and auto-recognition by the panel. Once it is installed and the panel is powered on, the AxTraxNG Server recognises the expansion, 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.
