PFSA103B STU48 3BSE002487R1Product NameABB PFSA103B Surface Tension Unit (STU48) Controller Module (Ordering Code: 3BSE002487R1); 48-Zone Web Surface Tension Monitoring & Control for Industrial Web Processing Lines (ABB Process Automation/Web Handling Systems).Product DescriptionThe PFSA103B (3BSE002487R1, STU48) is a dedicated Surface Tension Unit (STU) controller module engineered for industrial web processing (films, metal strips, paper, laminates) to monitor and control surface tension across 48 independent zones in full-width web applications. It integrates zone-specific sensing, signal conditioning, and control logic to detect surface energy variations, enabling real-time quality control, defect prevention, and process optimization. Key features include industrial-grade electronics, compatibility with ABB’s web handling automation ecosystem, configurable alarms/interlocks, and fieldbus connectivity for SCADA/DCS integration. Typical applications include packaging, electronics, printing, automotive, and metal processing lines where consistent surface tension is critical to bonding, printing, coating, and converting operations. Note: This is not a general-purpose I/O or motion module; always verify compatibility with your web line’s STU sensors, master controller, and web width before ordering spares or upgrades.Key Parameters & Specifications (Consolidated, with Critical Notes)
