Ethernet connectivity in hazardous environments

July 2011 IS & Ex

New Ethernet products from MTL provide connectivity across the process plant.

Today’s industrial plants demand greater efficiency, higher reliability, increased levels of security and lower cost of ownership of field equipment and supporting networks across all the areas of modern processing. MTL’s new 9200-ET series of Ethernet products are suitable for use in extended temperature ranges and are certified for use in ATEX Zone 2 and UL Class 1 Div 2, ensuring dependability in the most extreme industrial environments. Features such as active IGMP provide multicast filtering to deliver optimised video surveillance solutions, while switch status over Modbus TCP delivers network status to the control engineer.

This new Ethernet range features multiport managed and unmanaged switches, Power over Ethernet (PoE) capability, multiple fibre-port options and Gigabit switches. The portfolio provides a core technology to the existing Tofino network security solution and wireless ranges and provides users with a complete suite of digital connectivity products.

The 9200-ETZ rack mount managed switches support Redundant Ring network topology providing high-speed recovery from network failures required for real-time automation networks. An extra degree of flexibility in network topology is provided with support for up to four Redundant Rings on each switch as well as supporting the open Rapid Spanning Tree Protocol (RSTP) for integration into the manufacturing execution system.

To meet customer requirements for in-depth Ethernet technical support from knowledgeable process industry specialists, MTL provides full customer assistance to simplify selection, installation and operation of Ethernet networks. This reduces the risk of installing and operating Ethernet networks in industrial process applications.
