Product Name
PFSA145 3BSE008843R1 Industrial-Grade Tension Controller (Approx. 3kVA)(Abbreviation: “PFSA145 Tension Controller”), a core component of ABB’s industrial process control product line, specifically engineered for precise tension regulation of web, wire, or film materials in continuous production processes. Its primary function is to maintain stable tension levels during material unwinding, processing, and rewinding—ensuring consistent product quality and preventing material damage in manufacturing sectors such as paper, plastic, metal processing, and textile.
2. Product Description
The PFSA145 3BSE008843R1 module is strategically positioned to address three core challenges in web/tension control: “high-precision tension stabilization under dynamic speed variations,” “seamless integration with production line drives and sensors,” and “robust operation in harsh industrial environments”. Typical application scenarios include: tension control of paper webs in printing presses (maintaining uniform ink application); film tension regulation in packaging machines (preventing stretching or tearing); and wire tension control in metal drawing processes (ensuring consistent diameter and mechanical properties).
Built on ABB’s proprietary tension control architecture, the module integrates a high-performance microprocessor, real-time tension feedback processing circuits, multi-protocol communication interfaces, and adaptive control algorithms. It delivers three key capabilities:
- Precision Tension Regulation: Equipped with a 24-bit high-resolution analog-to-digital converter (ADC) and adaptive PID control algorithm, it achieves tension control accuracy of ≤±0.1% of full scale (FS). The controller supports both “open-loop” (torque-based) and “closed-loop” (load cell feedback-based) control modes, adapting to diverse material types (e.g., elastic films, rigid metals) and production speeds (0-1000m/min). It automatically compensates for speed-dependent tension variations (e.g., centrifugal force during rewinding) and material elasticity changes, ensuring stable tension across the entire production process.
- Flexible System Integration: Features comprehensive input/output interfaces, including 2 × analog inputs (4-20mA, for load cell tension feedback), 4 × analog outputs (4-20mA, for driving frequency inverters or servo drives), 8 × digital inputs (dry contact/NPN, for limit switches or start/stop signals), and 4 × digital outputs (relay/transistor, for alarm or interlock control). It communicates via Modbus RTU, Profibus-DP, and ABB’s proprietary MasterBus 300 protocol, enabling seamless connection with ABB ACS series drives, third-party inverters (e.g., Siemens SINAMICS), load cells (e.g., ABB PFTL series), and upper-level DCS/PLC systems (e.g., ABB 800xA, Siemens S7-1500).
