Actisense PRO-NBF-1 Type Approved NMEA 0183 Buffer
The PRO-NBF-1 NMEA 0183 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.
Safely connect one Talker to six Listeners with full isolation
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 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.
Helpful LEDs indicate power, input, and output operation.
