Festo鈥檚 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.

Lower energy consumption and component wear

The DHS 3000 VSD+ includes an integrated control system with frequency converter that adjusts pump speed based on process requirements so the system delivers the required vacuum level in each section. Atlas Copco said this can reduce energy consumption and wear on moving components, which may help extend maintenance intervals and pump service life.

No oil emissions or other contamination

A gearbox transfers power from the motor to the screw. 鈥淲e have achieved a long service life for the gear wheels by using a cooled oil flow,鈥� said Carol Pignatelli, product manager at Atlas Copco. Because the DHS 3000 VSD+ does not use oil elsewhere in the pumping process, Atlas Copco said there is no risk of oil carryover. 鈥淲e have also equipped the DHS VSD+ with an air intake filter to protect operational process from dust and particles,鈥� Pignatelli said. The company said the oil-free design and simplified construction can help reduce maintenance costs.

Quiet, vibration-free operation

The DHS 3000 VSD+ is housed under a noise-reducing enclosure and includes the Elektronikon control system for monitoring operating time, downtime, errors, and alarms. 鈥淎tlas Copco supplies the DHS VSD+ as a complete plug-and-play unit that can be seamlessly and quickly integrated into any system,鈥� Pignatelli said.
