MRT Backplane

Different backplanes are used for connectivity and distribution of signals in MRT, which are divided into two main groups of Main and Lower Backplanes.

Main Backplane

Main backplane is used for connectivity between modules in digital section. There are three types of main backplanes available: BPM912, BPM912L, BPM912M and BPM912R.

Main Backplane provides connection between I/O cards and RTU module (which is responsible for controlling the system) in this system. Main backplanes are connected together by D-SUB 25 connectors, which include BACKPLANE BUS signals. Their power is connected through distinct careers to 12V power.
