Bourns RS-485 Evaluation Boards

Bourns RS-485 Evaluation Boards aid in evaluating circuit protection on RS-485 Serial Device Ports using TBU^® High-Speed Protectors (HSPs), Gas Discharge Tubes (GDTs), Transient Voltage Suppression (TVS) diodes and Metal Oxide Varistors (MOV) products. As part of the Bourns TBU HSP device solution with a low capacitance GDT, the RS-485 Evaluation Boards enable design engineers to increase the surge and transient protection level on RS-485 ports and house the entire circuit protection solution in a reduced PCB area.

RS-485EVALBOARD2 - aids in evaluating circuit protection on RS-485 Serial Device Ports using Bourns TBU HSPs, MOVs, and TVS diodes to meet required industry standards on RS-485 port interfaces. Constructed using FR4 PCB with nickel-gold plating on top and bottom sides, the RS-485EVALBOARD2 measures 50mm x 25mm x 1.2mm.

RS-485EVALBOARD3 - aids in evaluating circuit protection on RS-485 Serial Device Ports using Bourns TBU HSPs, MOVs, and TVS products to meet required industry standards on RS-485 port interfaces. Constructed using FR4 PCB with nickel-gold plating on top and bottom sides, the RS-485EVALBOARD3 measures 53.5mm x 25.3 mm x 0.85 mm.

RS-485EVALBOARD4 - aids in evaluating circuit protection solutions for RS-485 serial ports using Bourns TBU HSP, GDT, surge arrestor, and TVS diodes to meet required industry standards on RS-485 port interfaces. Constructed using FR4 PCB with nickel-gold plating on top and bottom sides, the RS-485EVALBOARD4 measures 35mm x 25mm x 0.85mm.
