Product Overview

The RS-485EVALBOARD3 from Bourns is a RS-485 port protection evaluation board 3. This evaluation board serves as an aid in evaluating circuit protection on RS-485 serial device port solutions using Bourns® TBU® high speed protectors (HSPs), FLAT® gas discharge tube (GDT) surge arrestors and transient voltage suppressor (TVS) products designed to meet the required industry standards on RS-485 port interfaces. The recommended Bourns® TBU® HSP solution offers enhanced performance features over competing technologies which can help the design engineer to increase the surge and transient protection level on RS-485 ports, placing the entire circuit protection solution into a smaller PCB area. Bourns has developed an RS-485 evaluation board manufactured using an FR4 PCB with nickel gold plating on the top and bottom sides. The default configuration of this board uses two GDTs w/FLAT® technology (GDT3 and GDT4) and one TVS diode (TVS3).
