RS-485 Serial Port - ESD / EFT / Surge Protection Solution Products TBU-CA065-300-WH Objective Compliance RS-485 (TIA/EIA-485) is a balanced data transmission scheme that uses voltage levels from -7 V to +12 V (max.) at data rates up to 10 Mbps. This solution provides protection against ESD, EFT, power and surge faults. IEC 61000-4-2 ESD Level 4 (8 kV / 15 kV) IEC 61000-4-4 EFT IEC 61000-4-5 Surge / Lightning SMBJ6.5A and SMBJ12A TVS Diodes with MF-RM012/240 Multifuse® PPTC Resettable Fuse Solution 2 TBU® High-Speed Protectors: TBU-CA065-300-WH 2 MOVs: MOV-10D201K 1 TVS Diode Array: CDSOT23-SM712 MOV-10D201K Alternate Recommendations Benefit This solution provides excellent protection for both indoor and outdoor applications. It also protects against 28 VRMS and 120 VRMS power cross condition.
