Today, OEMs of all stripes strive to supply equipment that is reliable, efficient, and safe to operate — and ultimately cuts operating costs and boosts productivity. But this is nothing new. Valve terminals — modular platforms that combine pneumatic valves with electronic interfaces — were invented two decades ago to help meet these same needs. Their success speaks for itself. Festo, Hauppauge, N. Y., for instance, has installed more than 100,000 units worldwide, and acceptance continues at a brisk pace. But the latest versions bear little resemblance to original designs. Capabilities now include not only pneumatics and I/O, but also electric drives, motion control, safety functions, and built-in diagnostics. Here's a closer look. When first introduced by Festo in 1989, "fieldbus-valve manifolds" offered several advantages over pneumatic systems built of stand-alone valves. In traditional systems, each individual valve needed a separate electrical connection and each solenoid coil had to be separately wired to the controller. Every valve also needed its own tubing and pneumatic connectors. This made installation expensive and presented plenty of opportunities for miswiring. More connections also meant lower reliability.
