Products Intrinsically Safe Ethernet » 9474-ET(G) Ethernet Barrier

The CSL 9474-ETG acts as a barrier so that an unsafe Ethernet Cable can be used in Zone 0Zone 1 and Zone 2 areas as well as Underground Coal Mines.


  • The 9474-ETG is an I.S. Gigabit 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 10/100/1000Mbps.
  • It is designed to allow OEMs to integrate I.S. Ethernet into an uncertified safe area device.
  • The Gigabit versions are suitable for IIB gas groups, the 100Mbps versions are suitable for IIC gas groups. All versions are suitable for Group I Mining.
  • DIN Rail mounting (cased version).
  • Compact dimensions (Cased W:72xH:90xD:60mm).
