NMEA expander NMEA expander - 2NMEAto2R


The scope of the module is the interconnection of devices on ships which are giving out the serial signals according to the NMEA 0183 standard. The 2NMEAto2R module consists of two identical redundant systems together with each 2 NMEA sources to a current signal which are sent out to two galvanically isolated RS422 outputs. The NMEA inputs are galvanically isolated from each other and from RS422 outputs. The system state of each system is output as the sum of alarm via a relay contact and LED. The status of the each system is signaled as a sum by a relay contact and LED.
