ABB PFEA111-IP65 is a
Compact Tension Measurement and Control Unit designed for industrial automation applications requiring precise tension monitoring and regulation. It belongs to ABB’s
PFEA series of tension electronics, specialized in handling dynamic tension control for materials such as films, wires, textiles, and paper. The
IP65 rating ensures robust protection against dust and water ingress, making it suitable for harsh industrial environments.
The PFEA111-IP65 serves as a critical component in closed-loop tension control systems, converting signals from load cells into actionable outputs for actuators. Its primary role is to maintain consistent tension in materials during manufacturing processes, preventing defects like stretching, tearing, or misalignment. Key functionalities include:
- Dual Load Cell Inputs: Supports two independent load cells (e.g., strain gauge-based sensors) 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 Outputs: Provides 0–10V or 4–20mA signals for controlling drives, brakes, or clutches, enabling real-time tension adjustments
- Digital Display: A 2×16 character LCD screen shows real-time tension values (sum, difference, or individual load cell signals) in units like N, kN, kg, or lbs
- Communication: Integrates with PLCs and SCADA systems via Profibus DP (GSD file included) or RS-485 Modbus RTU, facilitating seamless integration into automation networks.
