Description
The ABB PFEA113-20 (Catalog / Ordering Part Number: 3BSE028144R0020) is an advanced, high-performance Tension Electronics Module manufactured by ABB as part of its web tension measurement and control product line. Designed to interface directly with ABB load cells (such as PFCL, PFTL, and PFRL series), the PFEA113-20 processes high-precision mechanical force signals from moving web materials—such as paper, steel, film, and textiles—converting them into reliable analog, digital, and fieldbus process values for closed-loop industrial control systems.

Primary System Functions
- High-Precision Tension Processing: Excites connected load cells and processes raw microvolt signals proportional to mechanical web tension, delivering high measurement accuracy and stability.
- Multi-Channel & Segmented Roll Support: Capable of driving up to four load cells simultaneously. Multiple PFEA113 units can be combined to manage complex segmented roll arrangements (such as winders with up to 12 load cells).
- Gain Scheduling & Zero-Set: Features digital input or fieldbus-controlled switching (gain scheduling) to adapt dynamically to different web paths, material grades, or zero-setting operations.
- Fieldbus & Analog Integration: Transmits real-time sum, difference, or individual load cell values across 6 configurable analog channels or via the built-in PROFIBUS-DP interface directly to plant PLCs or DCS networks.
Servicing & Installation Guidelines
- DIN-Rail Grounding & Shielding: Ensure the metal base of the module has a solid, low-impedance connection to the metallic DIN-rail and cabinet Protective Earth (PE). Proper grounding is critical to maintain EMI immunity and RF emission compliance.
- Electrostatic Discharge (ESD) Protection: Sensitive internal microprocessors and analog signal conditioners require standard static precautions. Always wear a grounded anti-static wrist strap during handling or replacement.
- Parameter Backup via Keypad / Software: Document custom scaling factors, filter settings, and calibration profiles via the onboard display and keys before swapping or upgrading the module.
- Power Supply Isolation: Isolate 24 V DC auxiliary power supplies before plugging or unplugging rear terminal connectors to prevent electrical arcing or transient spikes on signal lines.
