Festo’s new VTUX valve terminal boasts modular design for flexible use

Festo introduced the new VTUX flagship valve terminal, which can serve as I/O, remote I/O, and decentralized I/O. These compact and rugged IP65/67-rated terminals can be located anywhere on a machine that boosts operational performance and original equipment manufacturer (OEM) installation productivity. VTUX modularity results in less inventory and lower overhead costs.

VTUX is both compact and lightweight, an advantage for end-of-arm tooling and conserving space on a machine or in a control cabinet. The terminal is made from a high-performance polymer so rugged and durable that these units can be placed in welding cells.

The key to the VTUX’s unparalleled flexibility is its modular design. For high flow rates up to 670 lpm, a high flow compact sub-base is used and for space saving needs. A single valve model can be used for both sub-bases, which simplifies ordering, stocking, and support. High flow and compact sub-basses of one or four valve positions can be mixed and matched on a terminal. VTUX terminals can have up to 128 valves with up to 128 solenoid coils. The VTUX also features vacuum capability.

VTUX offers a platform for a fully integrated vacuum solution allowing configuration of up to 16 vacuum channels per terminal. The platform enables bidirectional communication from the PLC to the vacuum generator. Vacuum and ejector pulse can be individually controlled. VTUX vacuum delivers high vacuum or large suction volume flows and can be combined with valves. Parameters can be changed via teach-in from the PLC during operation. There is an integrated vacuum sensor for continuous monitoring of actual values and there is a parameter-based air saving function. The system monitors vacuum for early detection of faults or errors during operation.

The electronics side of the terminal offers the same flexibility as the pneumatics side by featuring mix and match modules. For example, users can add multiple analog or digital I/O modules, including I/O-Link. The modular concept continues through to the method of communication between controller and terminal. The choices include the new Festo Automation Platform (AP) for backplane speed communication in all top communication protocols. All AP-based modules appear to the control engineer to be under a single IP address, simplifying commissioning and allowing smaller and less expensive PLCs to be specified. Additional communication modules include IO-Link, AP-I for decentralized I/O, and multipin connector.

VTUX terminals are assembled and tested prior to shipment from the Festo Regional Service Center in Mason, Ohio, which means they are drop-in ready for installation. As a core Festo product, VTUX components are stocked globally for fast, assured replacement and minimum downtime wherever the machine is located. The modular design not only lowers inventory, but also decreases the learning curve, troubleshooting time, and repair. The VTUX offers an outstanding price/performance ratio.
