March 4th, 2014, Published in Articles: EngineerIT


MTL Instruments has announced the release of its 9400 series intrinsically safe (IS) Ethernet range and the launch of an enhanced power supply, 9491-IS, which incorporates MTL’s patented fast switch technology. The 9400 IS Ethernet range of hardware extech-282-02-group3devices that can deliver IS Ethernet into Zone 1 and Zone 0 hazardous areas. The deployment of Ethernet into process automation has long been hindered by the hazardous area classification in which the end device is often installed. Consequently the majority of industrial Ethernet installations have been in the factory automation environment. Additionally, in process automation it is preferred to use a single cable providing power and communications to the end device. The 9400 series delivers IS “Power over Ethernet” (PoEx), allowing live connection and disconnection of the end device in Zone 0 and Zone 1 hazardous areas, typically reducing the cost of installing the LAN in hazardous areas by 40%.
