The technical data of the RevPi Connect 4 is not precise regarding the norm about protection of logic system 4kV/8kV. Can you explain this in more detail?

• We can provide these answers:

  ESD (EN 61000-4-2) contact discharge: 4kV, air discharge 8kV

  • Surge (EN 61000-4-5): 0.75kV on 24V supply, 0.5kV on RS-485 and Ethernet ports

  • Fast Transients/ Burst (EN 61000-4-4): 2kV on Ethernet, RS485 and 24V

  • Immunity to conducted disturbances, induced by radio-frequency fields (EN 61000-4-6): 150kHz…30MHz / 20V on 24V supply, RS-485 and Ethernet

  • Radiated, radio-frequency, electromagnetic field immunity (EN61000-4-3): 80MHz…1000MHz, 20V/m; 1000MHz…2000MHz, 10V/m; 2000MHz…6000MHz, 10V/m
