The 9661-ETW is an MTL Intrinsically Safe (IS) Ethernet to Serial

4 Port Communication Module suitable for Zone 1 mounting with a

suitable Ex ib power supply, Zone 0 with a suitable Ex ia power supply.

The Module allows existing Intrinsically Safe equipment with an

RS485/RS422 or RS232/TTL port to become Ethernet Enabled via

either Wi-Fi (WLAN) or a Cat5/6 cable connection into an IS Ethernet

Network (LAN). The unit has 4 serial ports, each one supporting

either RS485/RS422 or RS232/TTL depending upon the configuration

required. There are 2 RJ45 (LAN) ports that support 10/100 IS Ethernet

connections – these allow ‘daisy-chaining’ of units together.

Power (12V DC) is supplied to the module either locally or using Power

over Ethernet (PoEx™) from the LAN port – This requires the PoEx

output to be wired to the Supply Input terminals by the user.

The compact and cost effective design makes it the ideal choice

for many applications such as Petrochemical – Process Monitoring,

Legacy Systems and Mining – Underground Communication Links,

Machine Monitoring and Legacy Systems.

Electrical connections are made via cage-clamp plug/socket terminals

along with a dual RJ45 type connector for the Ethernet LAN ports.

Twin SMA Style RF connectors allow one or two antenna to be

connected as required.

Minimise CapEx and maximise investment return with the revolutionary smart

universal marshalling solution, SUM5. MTL SUM5 combines five functions in

one modular design enabling one standard cabinet to deliver the lowest

lifetime costs and lowest installed cost while saving valuable space in a control

room.

MTL SUM5 offers a single cabinet design, with ‘plug and play’ configurable

modules for the five key marshalling functions. This eliminates the need for

intricate wiring to interconnect the components, ultimately improving uptime

and reducing the cost of wiring, installation and maintenance.

MTL SUM5’s modular design simplifies marshalling and provides increased

flexibility throughout the product lifetime. Loop disconnect is integrated in

every terminal, so loops can be easily isolated, which together with the modular

design, simplifies maintenance and keeps associated costs to a minimum.

MTL SUM5 reduces the number of marshalling components by 65% compared

to a standard solution. One MTL SUM5 universal ADIO isolator module supports

the functionality provided by 20 different MTL4500 single channel modules,

while the configurable parameters enable support for an even wider range of

applications. The marshalling solution provides comprehensive diagnostics,

notifying the process managers when action is required. It also features LED

indicators for power, function and status, which simplifies commissioning and

troubleshooting. The MTL SUM5 modules are designed for both cabinet mounting

in the control room, or field mounting. They are certified for ambient operating

temperatures from –40 to +70°C and for mounting in a Zone 2 hazardous area,

thus providing reliable operation in remote locations.

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.

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.

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.

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.

1. Division 1 hazardous areas

• Connectivity into Zone 0

• Intrinsically safe Power over Ethernet (PoEx™)

enables live connection or disconnection in Zone 0 and 1

• Serial-to-Ethernet Gateway

• Copper to Fibre-Optic Media Converter

• IS Ethernet Switch

• IS Ethernet Isolator

• IS Wireless LAN Access Point/Bridge

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 9461-ET is designed for hazardous-area mounting inside a suitable

enclosure with intrinsically safe Zone 1. ATEX and IECEx certification

and Division 1 FM USA and Canada approvals. The ATEX and IECEx

approvals cover both surface industry and mining applications.

The design is based on a high performance ARM9 155MHz 32-bit RISC

Processor (ARM926EJ-S).

The gateway may be powered by an intrinsically safe power supply or

by Power over IS Ethernet (PoEx) providing intrinsically safe power and

Ethernet communications over a single Cat5e cable.

10/100Mb Ethernet twisted pair (Cat5e) RJ45 connection (100metres

length max..).

Status LEDs are provided on the front panel to indicate:

• ’Power On’

• Network Link established

• Tx/Rx activity for all COM ports

Configuration is via a Microsoft® Windows™ interface which enables

the IP address and the protocol conversion to be defined.

The Gateway can also act as the host processor for the 9466-ET

Managed Ethernet Switch giving remote access to the switch’s

management features over the Ethernet network.

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