The first possibility cannot be used with every valve manifold manufacturer, the second requires a great deal of work and high costs. The XV System from B&R provides the solution.
Using XV, various valve manifolds can be connected easily and economically. It allows standard devices to be used with multi-pin connectors instead of valve manifolds with an expensive fieldbus. Regardless of the type, valve manifolds are always integrated in the same way. The application program and circuit diagrams are reused as is without changes.
The XV module is connected directly to the valve manifold. The connection to the controller is made using the integrated connection on the central backplane. The entire electronic circuit used to control the valves is housed in a 25-pin DSUB connector that is simply connected to the multi-pin valve manifold. XV is open for all leading manufacturers such as Bürkert, Festo, Rexroth, Norgen and others.
The decentralized XV connection module is available for 8, 16 or 24 valves. The value manifold connection module is available with IP67 protection for use in rough environments.
