Direct control of Festo valves using AS-Interface

Bihl+Wiedemann has developed the active distributorBWU3577 with integrated AS-i chip especially for controlling Festo valves CPE14 / VUVG-L14. Use it to easily incorporate Festo valves into the AS-i network using pre-assembled M8 cables.


The especially compact form factor is optimized for the cable duct and allows you to create individual cable routing scenarios. Since the voltage is provided from AS-i, no separate cable needs to be routed for power supply. And the physical separation of valve and module makes it simple to replace components.


Other advantages: you can connect valves with a high standard nominal flow rate – and depending on the configuration even a larger amount of them. In addition, the distributor is especially flexible and attractively priced.
