ABB PFEA112-20 Tension Measurement Controller

Description

ABB PFEA112-20 Tension Measurement Controller

Product Overview

The ABB PFEA112-20 is a versatile, high-precision web tension electronics unit from ABB’s Tension Electronics PFEA112 series. It processes signals from up to two Pressductor® load cells to calculate real-time web tension (total tension, difference, or individual load cell signals) in continuous web processing applications.

The PFEA112-20 model represents the IP65-rated enclosed version, designed specifically for harsh industrial field environments outside electrical cabinets. It features an integrated display, operator control keys, configurable analog/digital I/O, and optional fieldbus connectivity (such as Profibus-DP).

Technical Specifications

Key Advantages

• High Precision & Fast Response: Provides real-time processing of force transducer signals to ensure precise tension measurement at high web speeds.
• IP65 Field Installation: Enclosed housing enables direct installation on machine frames near load cells, reducing long transducer cable runs and signal noise.
• Versatile Signal Processing: Calculates total web tension, left/right individual tensions, or tension difference across the roll.
• User-Friendly Setup: Easy commissioning via the local LCD display and keypad without requiring external software tools.
• Seamless Automation Integration: Standard analog outputs and optional Profibus-DP allow straightforward connection to PLCs, drives, or DCS platforms.

Important Usage & Installation Precautions

• Load Cell Compatibility: Use strictly with supported ABB Pressductor® load cell sensors to maintain calibration accuracy and signal integrity.
• Grounding & Shielding: Connect load cell cable shielding directly to designated earth points to prevent electromagnetic interference (EMI) from high-power variable frequency drives (VFDs).
• Power Supply Quality: Supply the unit with a stable, filtered +24 V DC source within the specified voltage range (18–36 V DC).
• Cable Entrance Glands: Maintain the IP65 rating by properly tightening all cable entry glands on the bottom of the field enclosure.
• Zeroing and Calibration: Perform zero setting and weight/force calibration during installation with no web tension present to establish an accurate reference baseline.

Applications

• Paper & Pulp Converting: Monitoring and controlling web tension in papermaking, slitting, rewinding, and coating machines.
• Printing Presses: Continuous tension control across paper, film, or foil webs in offset, flexographic, and rotogravure printing lines.
• Plastics & Film Extrusion: Web tension regulation during film blowing, casting, laminating, and slitting operations.
• Metals & Foil Processing: Precision measurement in light metal foil rolling, slitting, and coil handling processing lines.
