Products Intrinsically Safe Ethernet » OEM » CSL BxLAN


The CSL BxLAN acts as a barrier so that an unsafe Ethernet Cable can be used in Zone 0, Zone 1 and Zone 2 areas as well as Underground Coal Mines.


  • The BxLAN is an I.S. Interface that allows a Zone 2, uncertified safe area device, or an Ex d device to connect to other IS 9400 Series Ethernet Equipment in the Hazardous Area.
  • It uses the same CSL Patented circuits as the ExLAN for I.S. Devices. 
  • But uses an enhanced Voltage Clamping circuit to give non-IS Devices Ethernet connectivity.
  • The two ports support speeds of 10/100Mbps.
  • It is designed to allow OEMs to integrate I.S. Ethernet into an uncertified safe area device.
  • Compact dimensions (OEM W:40xH:78xD:20).
  • Operating Temperature: -40ºC to +70ºC.
