MTL Instruments has announced the release of the 9400 Series intrinsically safe Ethernet range, as well as the launch of an enhanced power supply, the 9491-IS, which incorporates MTL’s patented Fast Switch technology.
The 9400 IS Ethernet is a range of hardware devices that can deliver intrinsically safe Ethernet into Zone 1 and Zone 0 hazardous areas. The deployment of Ethernet into process automation has previously been hindered by the hazardous area classification in which the end device is often installed. In process automation it is preferred to use a single cable providing power and communications to the end device. The 9400 Series delivers intrinsically safe 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.
The 9400 Series comprises a wireless LAN access point, managed Ethernet switch, copper to fibre media converter and serial gateway that are certified to for mounting in a Zone 1 hazardous area with connectivity into Zone 0. Zone 2 mounting IS Ethernet isolator and associated IS power supply complete the product range. The 9491-IS power supply uses MTL’s patented Fast-Switch technology to allow live power connection or disconnection without the need for a gas clearance certificate.
The Ethernet gateway gives legacy intrinsically safe equipment Ethernet connectivity by allowing conventional serial communication port equipment to be connected to an Ethernet network. This enables easy integration of a wide range of IS serial measurement devices, including analysers, dust monitors, weighing systems, I/O, displays etc. into today’s control systems.
The IS wireless LAN product is a multifunctional module that can be used as an 802.11 a/b/g/h access point, wireless bridge or wireless repeater. This provides hazardous area infrastructure for the mobile operator using intrinsically safe PDAs anywhere on the process plant.
Why secure industrial communication depends on deployment as well
Fieldbus & Industrial Networking
The Industrial Security Harmonisation Group has released a joint industry perspective highlighting a critical truth in industrial cybersecurity: secure communication is not determined by protocols alone, but by how they are deployed and managed in real-world environments.
