Product Description
The Festo MPA-CPI-VI is a highly expandable and modular valve terminal featuring high-performance valves in a sturdy metal housing with metal linking . The internal communication system uses serial linking (CPI) and communicates with the higher-level controller via a CPX fieldbus connection, supporting up to 128 pneumatic valves per terminal . With the ability to combine two valve sizes (10 mm and 20 mm) on one terminal and ATEX Zone 2 certification for potentially explosive gas atmospheres, the MPA-CPI-VI delivers exceptional scalability and reliability for demanding industrial automation applications.
