Typical Applications

The figure below (view Figure 2.1 on page 10) shows the typical usage of Ethernet Isolators
within an Ethernet network. Using standard Ethernet cable (for cable parameters see chapter
2.4) and hardware, an up to 100 m long intrinsically safe connection can be established to
connect the hazardous area and the network in the safe area. It is also a fast and easy way to
bridge the Ethernet network through a Zone 0 or Zone 1 hazardous area. One Ethernet Isolator
is required at each end of the intrinsically safe line.
The Ethernet Isolator requires a 24 VDC power supply.
