MTL Instruments offers the 9460-ET Series of cost-effective Intrinsically Safe (IS) Ethernet equipment that can be installed and maintained easily in hazardous areas.
Different methods are used in process automation to power and communicate with end devices, including 4-20mA, a variety of different Fieldbus standards, serial communications such as RS232, RS422 and RS485 as well as video, telephony and Ethernet.
Ethernet is the ideal solution where applications require high bandwidth 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.
Use of Ethernet in hazardous areas is very rare because of the high cost of installation and the limitations involved in carrying out maintenance.
The 9460-ET Series from MTL Instruments provide cost-effective Intrinsically Safe (IS) Ethernet equipment for installation in hazardous areas with easy maintenance.
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.
The 9460-ET Series of IS Ethernet equipment consists of IS Copper to Fibre Converter, IS Ethernet Switch, IS Ethernet Isolator, IS Serial – Ethernet Gateway and IS Wireless AP/Bridge with all components being certified IECEx.
