Product Introduction
The ABB PFEA112-20 3BSE030369R0020 is a Profibus-enabled tension electronics unit from the PFEA11x v2.1 family. It connects to two ABB Pressductor load cells, processes the sensor signals, and provides analog and fieldbus outputs for monitoring and closed-loop tension control.
Compared with PFEA111-20, the PFEA112-20 adds a Profibus-DP interface, making it easier to integrate tension values directly into Siemens, ABB, or other PLC/DCS systems without relying solely on analog signals. It is suitable for rolling mills, processing lines, and web handling systems where stable tension measurement and digital communication are both required.
The “-20” suffix indicates the sensor input range class. If the application requires a different input range, PFEA112-65 or another variant may be needed. For systems requiring more analog I/O or additional digital inputs, PFEA113 should be considered.
QA & Testing SOP
- Order code verification: Confirm PFEA112-20 and 3BSE030369R0020 on the nameplate. Verify it is the IP20 DIN-rail version required by the cabinet.
- Visual inspection: Check housing, terminal blocks, Profibus port, display, and DIN-rail clip for damage or corrosion.
- Power-up test: Apply DC 24 V and verify normal display start-up and absence of fault indications.
- Load cell input check: Confirm correct connection of two Pressductor sensors, cable shielding, and grounding.
- Profibus and output check: Verify Profibus-DP station address, GSD file mapping, and analog voltage/current outputs. Full validation requires connected load cells and correct mechanical arrangement.
Installation Pitfalls & Guide
❗ Confirm the correct revision. The order code 3BSE030369R0020 should match the existing unit. Earlier market listings may show 3BSE030369R20 or 3BSE050091R20; always verify against the nameplate before replacement.
❗ Do not substitute PFEA111 for PFEA112 without checking communication. PFEA111 does not include Profibus-DP, while PFEA112 does. Replacing one with the other may break PLC/DCS integration.
❗ Match the sensor input range. The “-20” suffix must correspond to the installed Pressductor sensors. Using a different range version may cause scaling errors.
❗ Verify Profibus configuration. Confirm station address, baud rate, GSD file, and PLC/DCS I/O mapping before commissioning.
❗ Keep it in an IP20 cabinet. This DIN-rail version is not suitable for direct washdown or outdoor installation.
Replacement steps:
- Pre-install: Record existing parameters, load cell wiring, analog output scaling, Profibus address, and display settings.
- Removal: Isolate 24 VDC supply, disconnect load cell and output wiring, then release the unit from the DIN rail.
- Install: Mount the replacement, reconnect sensor cables with correct polarity and shielding, and verify Profibus and analog wiring.
- Commissioning: Energize, confirm display readings, verify A/B channel balance, check Profibus communication, and validate tension values before returning to closed-loop control.
Technical FAQ
Is 3BSE030369R0020 the correct order code for PFEA112-20? Yes, PFEA112-20 is commonly associated with the 3BSE030369R20 series, and 3BSE030369R0020 appears as a full revision format. Still confirm the exact revision on the existing nameplate before replacement.
an replace PFEA111-20? Functionally it can measure tension from two Pressductor load cells, but PFEA112-20 adds Profibus-DP. If the system does not use Profibus, it may still work, but wiring and configuration should be verified.
an replace PFEA113? Not directly. PFEA113 supports more load cell inputs and more analog I/O. Substitution requires checking cabinet wiring, PLC/DCS mapping, and system configuration.
Do you offer price flexibility? Yes. Pricing depends on condition, revision visibility, quantity, and urgency. New original stock and tested surplus units are quoted separately.
What warranty is included? Typical coverage is 12 months from delivery for functional defects, excluding incorrect wiring, parameter mismatch, or damage from improper installation. Final terms are confirmed on the quotation.
If you can share a photo of the existing nameplate or the connected load cell model, I can confirm whether this is a direct drop-in replacement for your tension system.
