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.
