Product Overview

The ABB PFEA113-20 is a high-precision tension electronics unit designed to interface with Load Cells to provide accurate web tension measurement in demanding industrial environments. As part of the Tension Electronics PFEA series, this specific model (3BSE050092R20) offers a sophisticated solution for processing signals from up to two load cells. It serves as the critical link between mechanical force sensing and the automated control system, ensuring stable material processing and preventing breakage or deformation in continuous production lines.

Hardware Parameters and Physical Specifications

• Display: Integrated 4-digit LED for real-time tension monitoring and local diagnostics.

• Connectivity: Profibus-DP interface for seamless integration into higher-level PLC and DCS architectures.

• Supply Voltage: 24 V DC nominal input requirements.

• Signal Output: High-resolution analog outputs for local control loops.

Industrial Deployment Scenarios

The PFEA113-20 is engineered for sectors where material web consistency is paramount to product quality. Its robust processing capabilities make it ideal for the following environments:

• Paper and Pulp Mills: Managing high-speed winding and slitting operations where constant tension prevents paper breaks.

• Converting and Printing: Ensuring precise registration and overlay by maintaining uniform tension across film or foil substrates.

• Steel and Metal Processing: Monitoring force on pickling lines or cold rolling mills to protect rollers and material integrity.

• Textile Manufacturing: Controlling the let-off and take-up tension in weaving or dyeing machines to avoid fiber stretching.

FAQ

Q: Does the PFEA113-20 support digital communication protocols?

A: Yes, this model is equipped with a Profibus-DP interface, allowing for high-speed digital data exchange with industrial control systems.

Q: Can this unit handle inputs from more than one load cell?

A: The PFEA113-20 is designed to process signals from two separate load cells, typically used on either side of a roller to calculate total tension.

Q: What is the primary difference between the PFEA113 and the PFEA111 models?

A: While the PFEA111 is a cost-effective basic version, the PFEA113 series adds advanced features such as the Profibus-DP fieldbus connection and enhanced diagnostic capabilities.

Q: Is the unit shipped pre-calibrated for specific load cell types?

A: While it is compatible with a wide range of ABB load cells, final calibration must be performed on-site using the unit’s menu system to match the mechanical geometry of your specific machine.

Q: What power source is required for the 3BSE050092R20?

A: The device operates on a standard 24 V DC power supply, making it compatible with most industrial control cabinets.
