Today in Process Automation many different methods are used to power

and to communicate with end devices. Such methods may include

4-20mA; a variety of different fieldbus standards; serial communications

- including RS232. RS422 and RS485; video; telephony and Ethernet.

Where applications require high bandwidth, Ethernet is the ideal

solution as it provides open connectivity and can be combined with

Ethernet Remote I/O and Linking Devices to connect to low bandwidth

4-20mA and fieldbus systems. But Ethernet has rarely been used in

hazardous areas because of the high cost involved and the limitations

involved in order to carry out maintenance.

The 9460-ET Series provides cost-effective Intrinsically Safe

(IS) Ethernet equipment that can be installed and maintained

easily in hazardous areas. The intrinsically safe hazardous

area certification permits the components to be mounted in a

Zone 1. or Division 1 hazardous area with connectivity into

Zone 0 and the associated apparatus certification of the

9468-ET IS Ethernet isolator and 9491-PS IS power

supply allow this equipment to be mounted in a

Zone 2 hazardous area and connected to intrinsically safe equipment in

a Zone 0 or 1. or Division 1 hazardous area.

In Process Automation it is also preferable to use a single cable to

provide both power and communications to the end device. The 9460-ET

Series 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.

The 9461-ET Ethernet Gateway provides existing intrinsically safe

equipment with “Ethernet connectivity” by allowing conventional serial

communication equipment to be connected to an Ethernet network.

Many intrinsically safe devices such as analysers, weighing systems, dust

monitors, etc. have RS232. RS422 or RS485 serial connectivity. Providing

these devices with Ethernet connectivity offers considerable hardware

and integration cost savings.

The 9465-ET Copper to Fibre Optic Media Converter enables an

Ethernet network to be extended over a much greater distance. A multi

mode fibre optic link running at 100Mbps can go distances of up to

2 km, or an extended distance of 5 km is achievable at 10Mbps. With

single mode fibre longer distances are supported.

The 9466-ET Ethernet switch allows the interconnection of intrinsically

safe Ethernet networking components via its 5 ports. It also enables a

copper Ethernet network to be extended beyond the 100 metre distance

limit between Ethernet devices.

The 9468-ET is an intrinsically safe Ethernet isolator enabling Ethernet

devices in Zone 2. or a safe area, to communicate with intrinsically safe

Ethernet networking components operating in the hazardous area. A

further application is the use of a pair of 9468-ET isolators to permit an

Ethernet cable to cross a hazardous area.

The 9469-ETplus Intrinsically safe Wireless LAN product is a multi

functional module that can be used as an 802.11a/b/g/h Access Point,

a Wireless Bridge or a Wireless Repeater. Many end users have

recognised the benefits of giving mobile operators access to control and

maintenance system data.
