NBF-3 NMEA Buffer

Product catalog summary

Overview
The NBF-3 NMEA Buffer by Actisense is designed to isolate and buffer NMEA 0183 data, enabling the distribution of data to multiple devices. It can distribute up to six identical, amplified data streams from a single source, ensuring consistent data quality and protection for connected devices.

Key Features

One OPTO-isolated input and six ISO-DriveTM outputs.
Compatible with RS422, RS232, and RS485 connections.
Pluggable screw terminals and power/input indicator LEDs.
DIN Rail mountable with up to 115200 baud rate.
1500V isolation on inputs and outputs.

ISO-DriveTM Technology
ISO-DriveTM technology provides isolated outputs, preventing ground loops and reducing risks of damage. It supports all connection types and allows outputs to float safely up to 1500 volts D.C from system ground.

Power Supply

Input Supply Voltage: 10 to 35V DC.
Input Supply Current: 100mA max @ 12V DC.
Listener Power Output Voltage: 10 to 35V DC.
Listener Power Output Current: 500mA max @ <= 30°C.

NMEA 0183 Port Specifications

NMEA Buffer 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. 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. Isolation on the input and outputs ensures the protection of the source Talker device and Listening devices.

NBF-3: Specifications Power Supply 1 What is ISO-Drive™? ISO-Drive™ technology is unique to our products and ensures each 'Talker' output is protected. ISO-Drive™ 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...
