• Safe Area or Zone 2 / Zone 22 mounting

The 9478-ET(G) is an Intrinsically Safe (IS) Ethernet Isolator

suitable for Safe Area or Zone 2 / Zone 22 mounting for connection to

intrinsically safe certified devices mounted in a Zone 0 location. The IS

Ethernet isolator allows the interconnection of a Zone 2 or uncertified

safe area device to the intrinsically safe 9400-ET range of Ethernet

networking products,operating in the hazardous area.

The isolating barrier provides a compact alternative solution to fibre

optic cable and media converters and for when it is desirable to use

Cat5e/6 cables in preference to fibre

Transparent operation - 10/100/1000Mbps, Full/Half Duplex with

AutoNegotiation. Supports IEEE 802.3: 10Base-T, 100Base-TX and

1000Base-TX.

The module is supplied as a DIN-rail mounting device.

There are 2x RJ45 (LAN) ports on the Safe Area side that support

10/100/1000 standard Ethernet connections – these can allow

‘daisychaining’ of units together. The single Hazardous Area RJ45

provides an IS LAN connection

* 9478-ETG supports 10/100/1000Mbs on safe area and hazardous area ports

9478-ET supports 10/100Mbs on safe area and hazardous area ports

10/100/1000Mb* IS Ethernet twisted pair (Cat5e/6) RJ45 connection

(100metres length max.) provide total galvanic isolation (Um=253Vac)

from safe to hazardous areas.

The module operates from a single supply in the Safe Area

of 10…30Vdc at approx. 24V @ 110mA or 12V @ 200mA.

The compact and cost effective design makes it the ideal choice for

many applications:

Petrochem -

Mining -

Process Monitoring, Galvanic Isolation...

Underground Communication Links,

Machine Monitoring….

Electrical connections are via cage-clamp and/or screw type plug/

socket terminals along with RJ45 type connectors for the Ethernet

LAN ports.
