Summary
Westermo RD-48 LV industrial RS-422/485 repeater and converter designed for extending and isolating industrial serial communication networks. Supports RS-422/485 communication, 2-wire to 4-wire conversion, galvanic isolation, and data rates up to 1.5 Mbit/s.

This was part of a custom electrical/electronics cabinet that was mounted on a yacht. As the cabinet was customized for the exact application on this vessel, we have disassembled/parted the cabinet out. All parts were reported to be working, but we lack the proper equipment to test them and confirm this. As such, we are selling them as working with a 30 day period for customers to test and ensure functionality and a 90 day warranty for peace of mind.

Includes Module Only, does not include instructions, mounting hardware, or original box.
