VL-SDN - Selector Device for NMEA
The VL-SDN is assigned to be used for redundant NMEA distribution. With its 2 galvanic isolated NMEA inputs the board can select automatically between both inputs to forward them to the 12xRS422 and 2xRS232 outputs. If one input is missing the module will switch over to the second one automatically. A possibility to switch over manually is also included. Due to its 2 power inputs 9-32VDC also the power source is redundant.
