ABB 3BSE002488R1 PFSA103C is a
Tension Control Module designed for industrial automation systems, specifically optimized for
closed-loop tension regulation in materials processing applications. It belongs to ABB’s
PFSA series of tension electronics, which integrates signal conditioning, control algorithms, and communication interfaces to ensure precise tension management in demanding environments. The
-S50 suffix denotes a
Standard Configuration with IP65 protection, making it suitable for harsh industrial settings with dust and water exposure
The PFSA103C serves as a critical component in tension control systems, converting signals from load cells or tension sensors into actionable outputs for actuators. Its primary role is to maintain consistent tension in materials like films, wires, textiles, and paper during manufacturing processes. Key functionalities include:
- Dual Load Cell Inputs: Supports two independent strain gauge-based load cells (e.g., ABB’s PFCL201C series) for measuring tension forces up to 50 kN with ±0.2% accuracy .
- Signal Conditioning: Features adjustable filtering (15–1500 ms) to reduce noise and stabilize measurements, ensuring reliable data even in high-vibration environments
- Analog & Digital Outputs:
- 0–10V/4–20mA analog outputs for controlling drives, brakes, or clutches.
- 1x RS-485 Modbus RTU interface for communication with PLCs, HMIs, or SCADA systems
- PID Control: Built-in proportional-integral-derivative (PID) algorithms optimize tension regulation, with configurable parameters for different material properties .
- User Interface: A 2×16 character LCD screen displays real-time tension values (sum, difference, or individual load cell signals) in units like N, kN, kg, or lbs .
