Intelligent Surge Protection for Process Technology

Phoenix Contact’s Plugtrab PT-IQ surge protection devices for MCR and process technology warn plant operators before protection of the plant is lost. To achieve this, each voltage-limiting component in the protective plugs is continuously monitored. If the performance limit has been reached as a result of frequent surge voltages, this is indicated by a yellow signal on the protective device and via remote signaling. At this time, the arresters are still functional and the plant is protected. However, replacing the component is recommended to prevent unnecessary servicing.

Plugtrab PT-IQ Ex protective devices are available for intrinsically safe areas. These devices can be installed in Ex Zone 2. The intrinsically safe protective circuits can be routed up to Ex Zone 0.

Thanks to multi-level monitoring and signaling, the plant operator always knows the status of protective devices and therefore has an overview of surge voltage protection in the plant. This intelligent surge voltage protection is available with traditional screw connection technology as well as innovative push-in connection technology. A controller supplies up to 28 protection modules with voltage and allows for connection of a central remote monitoring system.

Security Routers for Process Technology

Security is becoming increasingly important in the process engineering industry. With the new MGuard security router, Phoenix Contact is addressing this trend.

The security router meets the demanding hardware requirements of the process industry as well as the strict IT requirements for security products. Hardware features include an extended temperature range of -40 to +70 °C, IECEx and ATEX approvals for Ex Zones and corrosive gas testing in accordance with ISA-S71.04-1985 G3 Harsh Group A.

From a software point of view, existing MGuard security functions were enhanced with additional security components for OPC Classic, a protocol widely used in the industry. These include DPI (deep package inspection) and NAT (network address translation) functions. DPI allows for a high-quality OPC Classic firewall in the production facility, whereas NAT provides the option of integrating plants with identical IP addresses into a higher-level production network quickly, easily, and without address conflicts.
