The 2MLR-DBDH is a dual-channel hybrid redundant expansion drive interface board for the MasterLogic-200R series. It provides two RJ45 electrical ports and two LC multimode optical ports on a single PCB, enabling one-click creation of a dual-ring redundant hybrid media network. It supports cascading up to 31 expansion bases, with electrical segments up to 100 meters and optical segments up to 2 kilometers. If any cable or optical fiber is disconnected, automatic switching occurs within 50 ms, maintaining the same scan cycle as the CPU.
