Bourns presents two evaluation boards for RS-485-based applications. Using Bourns® TBU® High-Speed Protectors (HSPs), GDTs, TVS diodes and MOV products, the boards were developed as a design resource that streamlines evaluating circuit protection on RS-485 serial device ports. To meet the required industry standards on RS-485 port interfaces, the boards provide two different evaluation approaches. The Bourns® RS-485EVALBOARD1 includes two Bourns® TBU® High-Speed Protectors (HSPs), two Bourns® fast-acting GDTs and two Bourns® TVS diodes.
