PFEA112-20 ABB | Pressductor Tension Controller, New Original

Description

Product Introduction

The ABB PFEA112-20 is a tension controller from the Pressductor family, designed for web tension measurement and control in converting, printing, paper, foil, and textile applications. This unit interfaces directly with ABB Pressductor tension sensors, providing signal conditioning, calibration, and output signals for PLCs, drives, and operator interfaces. The PFEA112-20 processes raw sensor signals into accurate tension readings, delivering analog outputs for tension display and closed-loop control.

The Pressductor technology is based on the magnetoelastic principle, offering non-contacting, high-accuracy tension measurement with exceptional overload protection and long-term stability. The PFEA112-20 is the two-channel version of the PFEA110 series, suitable for applications requiring independent tension measurement on two separate zones or for dual-sided sensing on a single web. For process engineers and maintenance professionals, this controller provides the reliability and precision required for consistent product quality in high-speed web processes.

Key Technical Specifications

Key Selling Points & Differentiators

• Pressductor Sensor Integration: Designed specifically for ABB Pressductor tension sensors. Provides excitation, signal conditioning, and calibration in a single unit. No external signal conditioners required.
• Two Independent Channels: Measure and control tension on two separate web zones or provide redundant sensing on a single zone. Ideal for split-roll applications, unwind/rewind sections, and multi-zone converting lines.
• Automatic Calibration: Pushbutton calibration eliminates manual adjustments and scaling calculations. The unit automatically compensates for sensor mounting variations and mechanical tolerances.
• Versatile Outputs: Programmable 0 to 10 V or 4 to 20 mA outputs for direct connection to PLC analog inputs, drive speed references, or panel meters. Relay outputs for alarm or limit notification.
• Modbus Communication: RS-485 port with Modbus RTU protocol allows integration with PLCs, HMIs, and SCADA systems for remote monitoring, trending, and parameter adjustment.

Frequently Asked Questions (FAQ)

Q: Which Pressductor sensors are compatible with the PFEA112-20?
The PFEA112-20 is compatible with all ABB Pressductor tension sensors, including:

• PFCL series: Pillow block sensors for roll mounting
• PFTL series: Horizontal and vertical load cells for web tension
• PFEA series: Used with existing Pressductor sensor installations

If you have older Pressductor sensors (such as PFRL or PFVL series), they are also compatible. The calibration procedure accounts for sensor type and capacity.

Q: What is the difference between the PFEA112-20 and the PFEA111-20?
The PFEA111-20 is a single-channel tension controller, while the PFEA112-20 provides two independent channels in the same housing. The -20 suffix indicates the standard version with analog outputs and relay outputs. Both units share the same physical dimensions, power requirements, and user interface.

Q: Can I use this controller with non-ABB tension sensors?
No. The PFEA112-20 is specifically designed to interface with ABB Pressductor sensors, which operate on a unique magnetoelastic principle. Standard strain gauge load cells require different excitation and signal conditioning and are not compatible with this unit.

Q: What output options are available for connecting to a PLC?
The PFEA112-20 provides:

• Two analog outputs (0 to 10 V or 4 to 20 mA) per channel (total of four configurable outputs)
• RS-485 Modbus RTU communication for digital integration
• Two relay outputs for alarm or limit status

For most PLC integrations, we recommend using the analog outputs for simplicity. For applications requiring more detailed diagnostics or parameter access, Modbus communication is the preferred method.

Q: How do I calibrate the PFEA112-20?
Calibration is performed using the front panel buttons or through Modbus communication. The procedure is:

1. Install the unit and connect sensors
2. Perform a zero calibration with no web load
3. Perform a span calibration with a known weight or applied force
4. The unit automatically calculates the scaling factor and outputs

Detailed calibration instructions are provided in the ABB user manual (3BSE050091). We can also provide calibration support if needed.

Q: Can I mount this unit in a control cabinet with drives and other high-power equipment?
Yes, but with precautions. The PFEA112-20 is rated IP20 and is intended for installation in a clean, dry enclosure. We recommend maintaining separation from high-voltage power wiring and VFD output cables to avoid electrical noise interference. Use shielded cable for sensor wiring and analog outputs, and ground the shield at one end only per ABB installation guidelines.

Q: What testing do you perform before shipping?
For new factory-sealed units, we do not break the seal to maintain OEM warranty eligibility. Our QC process includes visual inspection of packaging integrity, verification of the PFEA112-20 part number and 3BSE050091R20 suffix, and anti-counterfeit checks. For units where testing is requested, we perform a full functional test including sensor simulation, analog output verification, relay operation, and Modbus communication. A test report is available upon request.
