MTL 9461-ET IS Serial to Ethernet Gateway
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
