The ABB PFEA111-65 (3BSE050090R65) is a highly specialized Tension Electronics Unit, primarily used in web tension control applications within various industrial processes. It's a key component in systems that require precise measurement and control of tension in continuous materials like paper, film, foil, or textiles.

Product Description

The ABB PFEA111-65 is a single-channel or dual-channel tension control unit (depending on configuration) that interfaces with load cells (often called tension transducers or pillow blocks) to accurately measure the tension in a moving web. It processes the analog signals from these load cells, provides a digital display of the tension, and offers outputs (voltage and/or current) that can be used by a drive or PLC to maintain precise tension control.

The "-65" in the model name specifically indicates an IP65-rated (NEMA 4) enclosed version. This means it's designed to withstand harsher industrial environments, offering protection against dust ingress and low-pressure water jets, making it suitable for installations where it might be exposed to moisture or particulates. It typically features a multi-language digital display and function keys for easy parameter setting and status checking.

Product Specifications

• Model Name: PFEA111-65
• ABB Part Number: 3BSE050090R65 (often seen as 3BSE050090 with "R65" suffix indicating the IP65 variant)
• Product Type: Tension Electronics / Tension Control Unit
• Channels: Often designed for 2 load cell inputs (A and B), which can be displayed individually (A, B), summed (A+B), or differenced (A-B).
• Input: Designed for signals from ABB's range of web tension load cells (e.g., PFTL 101, PFTL 201, PFTL 301, PFTL 100, PFTL 200, PFTL 300).
• Output: Adjustable analog voltage and/or current outputs for control signals.
• Display: 2x16 bit digital display, multi-language.
• Filtering: Adjustable filtering for stable tension measurement.
• Enclosure Rating: IP65 (NEMA 4), providing protection against dust and water jets. This distinguishes it from IP20 (unsealed) versions like PFEA111-20.
• Mounting: Designed for standard rail mounting or enclosed wall mounting due to its IP65 rating.
• Origin: Sweden.
• Weight (Net): Approximately 0.2 kg (for the PFEA111-20, the PFEA111-65 might be slightly heavier due to the enclosure).

Product Application Cases

The ABB PFEA111-65 is critical in industries that process continuous web materials, where maintaining consistent tension is vital for product quality, machine efficiency, and preventing material breakage.

• Paper and Pulp Industry: Used in paper machines, winders, rewinders, and coating lines to precisely control the tension of the paper web, ensuring uniform thickness, preventing wrinkles, and minimizing breaks.
• Printing Industry: Essential in printing presses (e.g., gravure, flexo, offset) for controlling the tension of paper or film during multi-color printing processes, which is crucial for registration accuracy and print quality.
• Film and Foil Production: Employed in extruders, laminators, slitters, and winders for plastic films, aluminum foils, and other flexible packaging materials to maintain consistent web tension, preventing stretching, breaking, and improving winding quality.
• Textile Industry: Applied in textile machinery, such as weaving, knitting, coating, and winding processes, to manage yarn and fabric tension, which impacts product uniformity and machine performance.

• Converting Industries: Any process that involves converting large rolls of material into smaller rolls or sheets, such as in the production of labels, tapes, or specialized papers, relies on precise tension control.
