Farnell stock two Bourns RS-485 evaluation boards. Bourns developed the two boards to provide customers using its TBU High-Speed Protector (HSP), metal oxide varistor (MOV), gas discharge tube (GDT) and transient voltage suppression (TVS) products a way of evaluating circuit protection on RS-485 serial device port solutions. Bourns TBU HSP solution can help design engineers increase the surge and transient protection levels on RS-485 ports and place the entire circuit protection solution into a smaller PCB area.

In addition to offering the two evaluation boards, Farnell stocks almost 6,000 Bourns products. Engineers can also access design support including application notes. RS-485 is one of the most common interface standards, and due to their prevalence in industrial settings, RS-485 systems must be capable of operating in very noisy and harsh electrical environments. In order to avoid damage and overload of the system, the use of robust and reliable circuit protection is required.
