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.
