The MB805 is the mounting base of the PNI800 plant network interface in ABB’s Symphony® Plus system. It carries everything the module cannot: the two RJ45 Ethernet ports for the redundant PN800 network and the TB1 screw terminal for the 24 VDC supply. The base ships inside the PNI800K01 kit, but in the field it is ordered on its own — terminals work loose, cabinets get rebuilt, and a module without its base is a module that cannot be connected.
