DESCRIPTION
The 9478-ET(G) Gigabit Ethernet Isolator allows the interconnection of a Zone 2 or
uncertified Safe Area device to the Intrinsically Safe 9400/9600/947x series of Ethernet
networking products and other compatible devices operating in the Hazardous Area
or to another 9478 device in the Zone 2 or Safe Area with the IS Cat5 cable passing
through Zone 1 or 0 Hazardous Areas.
The isolator provides a compact alternative solution to fibre optic cable and media
converters and for when it is desirable to use Cat5e cables in preference to fibre while
still providing total galvanic isolation.
The module requires a single supply from the Safe Area of 24Vdc at 110mA or 12Vdc
at 200mA (approx).
Electrical connections are via cage-clamp and/or screw type plug/socket terminals
along with RJ45 type connectors for the Ethernet LAN ports.
