Bourns Announces Availability of Two New Evaluation Boards for RS-485-based Applications

Boards Are a Design Resource that Aids in Evaluating Circuit Protection on RS-485 Serial Device Ports

RIVERSIDE, Calif.- Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the availability of two new evaluation boards for RS-485-based applications. Using Bourns® TBU® High-Speed Protectors (HSPs), GDTs, TVS diodes and MOV products, the new 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 new 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. The Bourns RS-485EVALBOARD2 uses Bourns® TBU® High-Speed Protectors (HSPs), MOVs and TVS products.

"Bourns designed the evaluation boards to help developers more quickly and easily determine the circuit protection required for their applications that use RS-485 serial device ports," said Ian Doyle, product line manager of semiconductor products at Bourns, Inc. "The evaluation boards demonstrate that with Bourns® TBU® HSP solutions, we are able to offer enhanced performance features over competing technologies in terms of increased surge and transient protection levels on RS-485 ports that also enable an entire circuit protection solution to fit into a smaller PCB area."

Bourns' RS-485 evaluation boards are offered through the company's distribution sales partners, with inventory available immediately at Digi-Key, Farnell and Mouser. As a pricing example, the Bourns RS-485EVALBOARD2 is priced at $20.00 in 10 piece quantities.

For more information, Bourns has produced a demonstration video that explains the use and benefits of its RS-485 evaluation boards in assessing port protection performance: lepage&v=dvCscFwlM_w
