Eaton MTL 9474-ET/ETG and BxLAN-OEM intrinsically safe ethernet barriers

Eaton's Crouse-Hinds series MTL intrinsically safe ethernet interfaces provide connectivity between non-IS and IS ethernet networks. The interfaces are available in several versions to suit different applications.

Boxed type

• 9474-ET: 10/100Mbps Ethernet Interface
• 9474-ETG 10/100/1000Mbps Gigabit Ethernet Interface

OEM PCB Type

• BxLAN 10/100Mbps Ethernet Interface

The two Ethernet LAN ports are provided with RJ45 connectors, while the two IS safety earth conductors are terminated into screw type terminals. The Ethernet LAN ports are marked up HAZ and SAFE. The connection going into the Hazardous Area must be plugged into the RJ45 marked HAZ and the Safe Area device is connected to the port marked SAFE.Ê

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.
