Safely drive up to six NMEA Listeners, with power distribution for the connected Talker. The NBF-3 NMEA Buffer isolates and buffers NMEA 0183 data, with the power to drive multiple devices. Able to distribute up to six identical, amplified streams of data from one source. The NMEA signals are buffered to ensure that each Listener receives the data at the required voltage levels, providing consistent data quality. Isolation on the input and outputs ensures the protection of the source Talker device and Listening devices. ISO-DriveTM technology on the outputs and OPTO-isolation on the input enables you to connect the NBF-3 with complete peace of mind. The NBF-3 has the addition of power distribution for the NMEA Talker. By having power and data from the same source, cabling requirements are reduced and installation is made simpler.

NBF-3 Specifications Power Supply What is ISO-DriveTM? ISO-Drive™ technology is unique to our products and ensures each ‘Talker’ output is protected. ISODrive™ provides an isolated output, making installation simple and free from ground loops. This substantially reduces the risk of damage and hazards in connected equipment. The ISO-Drive™ output is compatible with all connection types (RS422, RS485 & RS232), making for easy installation of an NMEA 0183 data bus system. Outputs are separately isolated from each other and the input (Listener) circuit and can ‘float’ safely up to 1500 volts D.C...
