This small motherboard module is a interface extender to the RB-100 and RB-106 carrier boards. The RBM_90 plugs underneath the carrier board. The top view shows the 2 motherboard connectors. The bottom view shows the 3 Phoenix connectors for power, CAN and RS232. The RBM-90 has a low cost RC network instead of the Ethernet magnetics. Therefore only short Ethernet cables to connect within a system or a room are allowed. The maximum isolation voltage is only 50V.
