In Class I, Division 2 hazardous locations, pneumatic actuators have typically been controlled from cabinets located in safe areas. Long wiring runs can increase installation and commissioning time, make maintenance and troubleshooting more difficult, and limit future system expansion.
Festoβs VTUG-EX valve terminal provides fieldbus connectivity for use in Class I, Division 2 areas. Ethernet-based fieldbus communication connects the terminal directly to a PLC, reducing the need for individual actuator wiring over long distances.
The VTUG-EX supports EtherNet/IP, PROFINET, and PROFIBUS communication through interchangeable bus nodes. It can also connect directly to an IO-Link master. The terminal supports up to 24 valve stations, or 48 solenoid coils, and flow rates of up to 630 l/min (22 CFM). Hot-swap valve replacement, multiple pressure zones, and panel-mounted installation support maintenance and system configuration. Certifications, including UL Class I, Division 2 and IECEx, allow the VTUG-EX to be used in hazardous locations in multiple regions.
Festo builds control cabinets for hazardous locations
Automation systems in hazardous locations also require control cabinets designed to distribute power, communication, and control signals safely. These cabinets must meet the certification requirements for the environments in which they are installed.
Festo designs, builds, assembles, tests, and certifies control cabinets for hazardous and non-hazardous areas. The completed cabinets are delivered ready for installation. Festo also manufactures many of the automation components used in these cabinets, including valve terminals, air-preparation equipment, emergency-shutdown systems, and I/O products. This allows the cabinet and its components to be specified and integrated through a single supplier.
