Eaton MTL 9461-ET Intrinsically Safe Serial to Ethernet Gateway

• Serial to Ethernet Gateway

• Zone 1. Division 1 mountable in suitable enclosure

• Four serial-port intrinsically safe inputs:

2 x RS232/TTL

2 x RS485/RS422

• 10/100Mbs Ethernet

• ATEX / IECEx certified

• FM / FMC approved

• Wide temp. range –40°C to +70°C

• High Performance 32-bit processor

• PoEx™ Power over IS Ethernet option

The 9461-ET Ethernet Gateway gives existing intrinsically safe equipment

“Ethernet connectivity” by allowing conventional serial communication

port equipment to be connected to an Ethernet network.

Two 9-way D-type serial ports are provided which are RS232/TTL

compatible. In addition, the module’s front panel screw terminals

(T6 - T15) provide two RS485/RS422. 2- or 4- wire ports, giving a total of

four serial ports. All ports can operate at speeds up to 115K2baud.

Various protocols are available (e.g.: Serial Modbus, Modbus/TCP,

Ethernet IP etc) in addition to Serial Tunnelling.

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.
