Pneumatic valve manifold incorporates I/O link interfaceRexroth says that by introducing the I/O link interface on its LS04 pneumatic valve manifold, commissioning and maintenance maintenance are easier, and diagnostics are improved.

With the I/O link interface in Rexroth pneumatic components, it is possible to communicate process, diagnostic and parameterisation data directly at a very low field level and to utilise the available intelligence. The integrated, open I/O interface standard enables users to control Rexroth components such as actuators, as well as sensors from numerous manufacturers.

Thanks to the cyclical transmission of process data within 2ms and the possibility for reliable error detection and localisation, the I/O link connection increases productivity and reduces machine downtimes.


The new LS04 valve terminal system with integrated I/O link interface is easily incorporated into existing, decentralised automation architecture. Full compatibility with standard I/O enables mixed operation and simple retrofitting in already installed machines. Systems that already have an I/O link network installed do not require a second line to control the valve terminal system. The valve terminal system can be integrated into the existing bus system via I/O link.

With its compact dimensions, the LS04 valve terminal system with integrated I/O link interface is particularly suitable for small handling applications with high-speed requirements and restricted space. The new valve terminal system can control up to 32 coils on 24 valve positions, with a maximum flow rate of 320 l/min.
