Product Introduction
ABB PFEA113-20 (3BSE028144R0020) is an IP20 DIN-rail tension electronics unit built for continuous web processing lines. It reads force signals from up to four tension load cells and converts raw force readings into usable analog or bus data for drive controllers.
This unit includes local display and configurable I/O for multi-zone web lines. The Profibus-DP interface lets control systems pull individual cell readings, total tension, and diagnostic status without extra signal conditioning hardware.

Application Scenarios & Field Experience
Part 1 (Narrative Paragraph)
Multi-zone web lines often use 3 or 4 load cells across wide rolls. Older 2-channel tension units cannot capture all sensor points, forcing engineers to sum signals externally. External summing adds noise and calibration drift. PFEA113-20 handles four load cells natively and outputs total or differential tension directly to the drive loop.
Part 2 (Numbered List)
- Paper manufacturing: Wide web paper machines with multi-point tension monitoring for sheet stability
- Plastic film extrusion: Cast film lines with four load cells across the web width
- Metal foil processing: Thin metal foil slitting lines to prevent wrinkling or web breakage
- Textile finishing: Fabric coating lines with separate tension zones across wide material paths
Part 3 (Short Field Story)
A film producer’s 3-meter cast line used two separate 2-channel tension modules. The two units drifted apart after several months, creating uneven web tension and edge tearing. The team replaced both units with one PFEA113-20. Calibration became a single setup, and cross-web tension readings stayed consistent. Web break incidents dropped sharply within the first week of operation.
Standard Operating Procedure (SOP) for Quality Control
- Visual & Origin Inspection: Verify ABB OEM labeling, serial number, PCB condition, terminal block integrity and original factory seals for new original inventory.
- Live Rig Testing: Power at 24VDC, simulate load cell input signals, validate LCD readings, analog output scaling and Profibus-DP handshake.
- Firmware Verification: Read and record installed firmware revision; confirm I/O channel count matches OEM datasheet specifications.
- ESD-Safe Packaging: Secure terminal connectors, place unit in anti-static bag, seal and pack inside rigid carton for transit protection.
Frequently Asked Questions (FAQ)
Q1: Can PFEA113-20 replace older PFEA112 tension units? A: Partial replacement works, but PFEA113 has extra I/O and four load cell channels. Re-map Profibus data objects and re-tune tension loop parameters before commissioning.
Q2: What warranty do you provide for this unit? A: We offer a 12-month warranty. Warranty covers hardware defects under rated operating conditions. Overvoltage, reversed excitation wiring, or ESD damage void coverage.
Q3: What is the current stock and shipping timeline? A: We carry limited new surplus stock. Units ship within 3 business days after order confirmation. Larger project quantities require lead time; confirm stock before locking project schedules.
Q4: Can I adjust load cell calibration and zero offset on the local display? A: Yes, zero and gain adjustments can be done locally. Always save parameter backups before changes. Incorrect excitation or zero settings will produce false tension values.
Q5: Can I swap load cell wiring while the PFEA113-20 remains powered? A: Do not hot-disconnect load cell cables. Live disconnection creates signal spikes, triggers fault alarms, and can damage the internal excitation circuit. Cut power before modifying sensor wiring.
