Eaton MTL 9470-ET/G Gigabit intrinsically safe ethernet range

The Crouse-Hinds series MTL 9470-ET/G product range provides

cost-effective Intrinsically Safe (IS) gigabit Ethernet equipment that

can be installed and maintained easily in hazardous areas. 

The intrinsically safe hazardous area certification, along with the

associated apparatus certification of the 9478-ET/G IS Ethernet isolator

and 9492-PS-PLUS power supply, permits the components to be mounted

in a Zone 2 hazardous area with connectivity into Zone 0.

In process automation it is also preferable to use a single cable to provide

both power and communications to the end device. The MTL 9470 range

can deliver Intrinsically Safe Power over Ethernet (PoEx™) with a single

Cat 5e or Cat 6 cable, allowing live connection and disconnection of the

end device in Zone 0 and 1 hazardous areas.

Additionally, the Gigabit range is suitable for bandwidth intensive applications.
