ABB PFXA401S 3BSE024388R2 strip measurement and control unit
PFXA401S 3BSE024388R2 belongs to ABB Millmate400 series strip measurement and control unit. Mainly used in metallurgical steel rolling, papermaking, film, and foil production lines, it receives signals from position sensors and tension weighing sensors, completes strip deviation correction and tension measurement calculations, and outputs control signals to drive correction actuators.
ABB PFXA401S 3BSE024388R2 strip measurement and control unit
Product function
- Sensor signal acquisition and processing: Connect photoelectric, ultrasonic position sensors, and weighing tension sensors to complete signal conditioning, filtering, and calculation, and obtain strip offset and tension values.
- Strip correction closed-loop control: Based on the position deviation output control signal, the servo actuator is driven to achieve strip edge centering and center positioning correction, ensuring stable strip feeding.
- Tension measurement and calculation: Supports angle compensation of weighing sensors, calculates actual strip tension, completes tension monitoring, and can output tension values to the control system.
- On site debugging and simulation testing: Equipped with a simulation testing mode, it can simulate signals offline, making it convenient to debug and verify circuits without running the production line.
- Data communication interaction: through serial port, Ethernet and other Millmate series units ABB AC800M PLC、 Communication with the upper computer, uploading location, tension, and fault alarm information, and receiving remote parameter settings.
- Fault diagnosis alarm: detect sensor disconnection, signal overload, and internal module faults, output alarms, and facilitate maintenance personnel to quickly locate on-site problems.
