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.
Helpful LEDs indicate power, input, and output operation.
Features:
- One Opto-Isolated Input
- Six ISO-Drive™ outputs
- Outputs automatically track the input baud rate
- RS-232, RS-422 and RS-485 Listener compatible
- ISO-Drive separates the Listener from the Talker to protect both the PRO-NBF-1 and each connected device
- Wide compatibility means simplified installation
- Simple installation saves time and money and provides peace of mind
- Type Approved (RINA)
