Actisense PRO NMEA Buffer Model PRO-NBF-1 – Isolated Marine Data Distributor with 6 ISO-Drive Outputs and Pluggable Terminals

PRO NMEA Buffer - 1 OPTO Input, 6 ISO-Drive Outputs, Serial Port, Pluggable Screw Terminals

Safely connect one Talker to six Listeners with full isolation.

The Type-approved NMEA Buffer PRO-NBF-1 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 of the input and outputs ensures the protection of the source Talker device and Listener devices.

The NMEA Buffer has ISO-Drive technology on the outputs and OPTO-isolation on the input, which enables you to connect the NMEA 0183 Buffer with complete peace of mind.

The stainless steel housing makes the device rugged, sturdy, and gives it increased durability. The metal case also acts as an RF Shield, making the device an ideal addition to commercial installations.

To make installation quick and simple, the PRO-NBF-1 features 2-part pluggable connectors that allow use of screw terminals*, and a professional DIN Rail mounting system (DIN Rail not included). The device can also be mounted directly to the bulkhead.

The optional strain relief brackets can be provided to ensure reliable professional cable management.
