ABB PFEA111-65 3BSE050091R65

Product introduction

The ABB PFEA111-65 3BSE050091R65 is a compact, high-precision tension measurement and control unit, designed to monitor and regulate material tension in industrial processes. As part of ABB’s portfolio of process control solutions, it bridges load cells (sensors) and actuators (such as motors or brakes), ensuring consistent tension in applications like web processing, winding, or material handling.

This unit processes signals from two load cells, providing real-time tension data via its LED display and analog outputs. The PFEA111-65 3BSE050091R65 operates on 24 V DC, aligning with standard industrial control systems, and its IP65 rating makes it suitable for harsh environments with dust or water exposure. Its DIN rail mounting and compact size enable easy integration into control cabinets, making it a versatile choice for industries ranging from printing to metal processing.

Core advantages and technical highlights

Precision measurement: The PFEA111-65 3BSE050091R65 delivers ±0.1% accuracy across load cell inputs, critical for thin materials like plastic films or metal foils. A packaging plant using this unit reduced material waste by 18% by maintaining consistent tension during film winding, eliminating stretching or tearing.

Dual-channel flexibility: With two load cell inputs, it can measure differential tension—ideal for detecting misalignment in web processes. A paper mill used the PFEA111-65 3BSE050091R65 to identify uneven tension across a paper web, triggering adjustments to guide rollers and reducing edge trim by 22%.

Robust environmental resistance: IP65 protection ensures reliable operation in dusty or wet conditions. A textile factory installed the unit near water-based dyeing machines, where it continued to function accurately despite occasional splashes—unlike previous non-sealed units that required frequent replacement.

Simplified integration: The 0-3 A current output directly interfaces with variable speed drives (VSDs) like ABB’s ACS800, forming a closed-loop tension control system. A cable manufacturer reported that this plug-and-play compatibility cut commissioning time by 30% compared to third-party tension controllers.

Typical application scenarios

Plastic processing: In a blown film extrusion line, the PFEA111-65 3BSE050091R65 monitors tension in the film web as it exits the extruder. By adjusting the take-up roller speed via a connected VSD, it maintains tension within ±2% of setpoint, ensuring uniform film thickness and reducing roll defects by 25%.

Metal processing: A steel mill uses the PFEA111-65 3BSE050091R65 to control tension in a cold-rolling process. It measures tension in the steel strip via load cells, sending signals to hydraulic brakes to adjust pressure, preventing strip breakage during high-speed rolling and increasing production uptime by 15%.

Printing industry: In a flexographic printing press, the unit regulates tension in the substrate (paper or plastic) between unwind and print stations. Its fast response (10 ms) compensates for speed changes during splices, avoiding registration errors and reducing scrapped material by 20% compared to manual tension control.

Installation, commissioning and maintenance instructions

Installation preparation: Mount the PFEA111-65 3BSE050091R65 on a 35 mm DIN rail in a control cabinet, ensuring 50 mm clearance for ventilation. Use shielded twisted-pair cables (24 AWG) for load cell connections, grounding shields at both ends. Connect 24 V DC power with reverse polarity protection; verify voltage before final connection. For outdoor or wet areas, use IP65-rated cable glands to maintain enclosure integrity.

Maintenance suggestions: Inspect quarterly for loose connections or corrosion, especially in humid environments. Clean the display and vents with a dry cloth; avoid water contact despite IP65 rating. Calibrate annually using a certified tension calibrator, verifying 0-5 V output matches load cell input (e.g., 2.5 V = 50% of full scale). Replace load cell cables every 5 years to prevent signal degradation. The unit is hot-swappable; store spares in anti-static bags at 10°C to 30°C.
