Boards Evaluate RS-485 Apps

For analyzing circuit protection on RS-485 ports, the 485EVALBOARD1 and 485EVALBOARD2 boards employ two different evaluation approaches. The RS-485EVALBOARD1 includes two TBU High-Speed Protectors (HSPs), two fast-acting GDTs, and two TVS diodes while the RS-485EVALBOARD2 uses TBU HSPs, MOVs, and TVS components. As a pricing example, the RS-485EVALBOARD2 costs $20 each/10. BOURNS INC., Riverside, CA. (951) 784-3100.
