4. Product Introduction (Anti-Template)
When web tension fluctuates and material starts to wrinkle or break, the PFEA111-20 sits between the load cells and the control system to keep the signal clean and usable. It accepts two Pressductor-type load cells, calculates the total (SUM) and differential (DIFF) tension in real time, and delivers filtered analog outputs that a PLC or drive can act on immediately.
The compact IP20 housing mounts on standard DIN rail inside a control cabinet. Operators see individual channel, sum, and difference values on the multi-language display and can adjust filtering to match process dynamics. This basic but reliable unit is widely used on paper machines, film lines, metal strip processing, and textile winders where two-sided tension measurement is required without fieldbus complexity.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Origin is confirmed against ABB manufacturing data. Ordering code (3BSE028140R0020 / PFEA111-20), terminal condition, display function, and housing integrity are photographed and logged.
- Live Rig Testing – Module is powered at 24 V DC, connected to calibrated load-cell simulators, and verified for correct SUM/DIFF calculation, analog output scaling, filter response, and status LED behavior.
- QA & Anti-Static Packaging – After functional pass, terminals are inspected, the unit is cleaned, and it is sealed in anti-static shielding with desiccant and humidity indicator.
- Global Logistics & Export Compliance – Classified under the correct HS code for industrial measurement electronics. Packaging is rated for air and sea freight vibration; export documentation is prepared to minimize customs delays.

6. Technical Pitfalls & Integration Warnings
Load-Cell Wiring Errors – Incorrect polarity, shield grounding, or excessive cable resistance (beyond the 5 Ω allowance) produces offset or noisy readings. Always follow the ABB wiring diagram for the specific load-cell type.
Filter Setting Mismatch – Leaving the filter too slow hides real tension spikes; setting it too fast passes electrical noise into the control loop. Match the step-response time to the mechanical dynamics of the web section.
Power Supply Quality – The module expects a clean 18–36 V DC supply. Undervoltage or high ripple can cause intermittent status faults or output drift.
Cabinet Environment – The IP20 version must be installed inside a suitable enclosure. Exposure to dust, moisture, or conductive debris will eventually cause failures.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified PFEA111-20?
Stock units normally ship within 1–3 business days after payment clearance. Air freight to major industrial regions typically adds 3–8 days once customs processing is complete.
How many load cells does it support?
Exactly two. The higher-channel PFEA113 is required for four load cells.
What analog outputs are available?
One voltage output (–5 to +11 V) and one current output (0–21 mA), both scalable and filterable.
Is fieldbus communication included?
No. The basic PFEA111-20 is analog-only. PROFIBUS or Ethernet versions are the PFEA112 / PFEA122 models.
What is the difference between the –20 and –65 versions?
The –20 is the IP20 DIN-rail (unsealed) version for cabinet mounting. The –65 is the IP65 sealed version for harsher environments.
Can the display show individual load-cell values?
Yes. The multi-language display can show channel A, channel B, SUM (A+B), and DIFF (A–B).
Is the module still current?
Yes, the PFEA111 remains part of ABB’s active web-tension electronics portfolio, although newer ordering codes (e.g., 3BSE050090R20) may supersede older ones such as 3BSE028140R0020.
