ABB 3BSE028144R65 (corresponding model PFEA113-65) is an industrial-grade high-precision tension controller, belonging to the core component series of ABB tension control. It is positioned as a key equipment for precise detection and closed-loop control of tension of strip and linear materials in industrial production. Integrating four core functions: tension detection, signal conditioning, PID closed-loop control, and multi-channel expansion, it has advantages such as high precision, high stability, flexible adaptation, and convenient operation and maintenance. As a core component in ABB automation systems to achieve precise control of material tension, it is widely applicable to harsh industrial scenarios in wire and cable, optical fiber cable, papermaking, printing, textile and other industries that require precise tension control. It can effectively avoid problems such as wrinkling of materials due to insufficient tension and breakage due to excessive tension, ensuring production quality and efficiency.

This module mainly undertakes five core tasks: tension signal acquisition, precise tension control, signal conditioning, fault monitoring, and data interaction. It focuses on tension control of various strip and linear materials in industrial production, and can directly connect to 4 weighing sensors to collect tension feedback signals (millivolt level). Through the built-in PID controller for deviation processing, it outputs control signals to drive peripheral actuators (such as magnetic powder brakes and clutches) to realize full-automatic closed-loop control of tension. Relying on engineering-grade high-precision circuit design and signal isolation technology, the measurement accuracy reaches ±0.1% full scale, and the response time is <10ms, which effectively suppresses electromagnetic interference in industrial sites and avoids signal drift and measurement errors. It supports multi-unit display (N, kg, lbs, etc.), adapts to tension measurement needs of different industries, and can realize signal integration and multi-module cascading through Profibus-DP, Modbus TCP and other protocols. Up to 3 controllers can be connected in series to realize collaborative control of 12 sensors without additional conversion modules, effectively solving problems such as low on-site tension control precision, slow response, and difficulty in multi-equipment collaboration. It is widely used in production links such as material slitting, rewinding, and traction, providing reliable tension control support for the continuous, stable and high-quality operation of industrial production.

It adopts an industrial-grade modular design, providing two versions (DIN rail mounting version / IP65 sealed protection version). The surface is coated with a corrosion-resistant high-strength resin coating. The DIN rail version is suitable for 35mm DIN rail installation, and the IP65 sealed version can be directly installed in harsh on-site environments, dust-proof and splash-proof, facilitating dense deployment in control cabinets and flexible on-site installation, adapting to different installation scenario needs. Equipped with high-density pluggable terminals and dedicated module connectors, it can quickly complete the wiring of power, sensor signals, control signals and module replacement, greatly improving installation, commissioning and maintenance efficiency. The enclosure and circuit design comply with relevant industrial electromagnetic compatibility standards, with excellent anti-electromagnetic interference performance, which can withstand high-frequency noise from inverters in industrial sites, electromagnetic fields from high-power equipment, and harsh environments such as humidity and dust. It supports hot-swappable function, allowing module replacement without shutdown during maintenance, and supports online configuration, parameter setting and fault diagnosis through ABB special configuration software. The tension control logic can be customized according to different production process needs, making operation and maintenance convenient and efficient.
