Country of Origin
This precision adapter is engineered and manufactured by ABB in Sweden, the global center for ABB’s force measurement and web tension technologies.
Application Fields
The PXAH401 is essential for maintaining accuracy in high-speed web processing:
- Paper & Board Mills: Managing the transition of tension signals from wet-end to dry-end processing.
- Metal Strip Processing: Adapting load cell signals in heavy-duty steel or aluminum rolling mills.
- Converting & Printing: Ensuring precise tension feedback for thin-film laminating and high-speed printing presses.
- System Upgrades: Acting as a bridge when replacing legacy tension units with newer PFEA series controllers.
- Textile Manufacturing: Standardizing signal inputs for large-scale fiber processing machines.
Product Usage Instructions
- Placement: Mount the PXAH401 on a standard 35mm DIN rail. Position it close to the main tension electronics unit to minimize signal cable lengths.
- Wiring: Connect the load cell excitation and signal leads to the designated terminals. Ensure that shielding is continuous and grounded at the specified point to prevent signal drift.
- Signal Matching: Verify the jumper settings (if applicable) on the board to match the impedance and signal range of the specific load cells being used.
- Testing: Use a calibrated millivolt source or the “Manual Calibration” mode on the tension controller to verify that the PXAH401 is passing the signal correctly without attenuation.
- Grounding: Ensure the board’s ground terminal is bonded to the common system ground to protect against electromagnetic interference (EMI).
Product Technical Description
The PXAH401 acts as a rugged interface for the Pressductor® principle. Because Pressductor load cells generate a signal based on changes in a magnetic field (rather than traditional resistive strain gauges), the wiring and signal conditioning requirements are unique. The PXAH401 provides the necessary electrical environment to ensure these low-frequency AC signals are handled with minimal loss. It often functions as a “distribution point,” taking the raw inputs from two load cells (one for each side of the roll) and combining or conditioning them for a single input channel on a PFEA controller. Its heavy-duty terminal blocks are designed to withstand the vibration and mechanical stress common in heavy industrial machinery.
Q&A (Common Questions)
- Q: Is the PXAH401 a stand-alone controller?
- A: No. It is a passive or semi-active adapter board. It must be used in conjunction with a tension electronics unit like the PFEA111 or PFEA113.
- Q: Can this board be used with non-ABB load cells?
- A: It is specifically optimized for the electrical characteristics of ABB Pressductor technology. Using it with standard strain gauge load cells is not recommended.
- Q: What is the main cause of failure for this board?
- A: Mechanical damage to terminals due to over-tightening or moisture ingress causing corrosion on the signal paths.
- Q: How does this differ from the PXAH401 relative to earlier revisions?
- A: The 3BSE017235R1 is the standardized modern revision, featuring improved terminal accessibility and updated component materials for better longevity.
