Parkinson Technologies has introduced Model 81, a digital tension control unit, which is offered as a replacement for original units on Dusenbery slitter/rewinders.
The Model 81 replaces older Dusenbery tension control units (TCUís), including the Model 61 and Model 71 unwind controls and DEL Slowdown rewind controls. These older controls were custom-designed and featured technology that is now obsolete, according to Parkinson.
In addition to PLC control, the Model 81 TCU features an operator interface screen and recipe storage capabilities, making it easier for operators to store and recall optimal settings. Several of the Model 81 features were based on field-proven control components used by Key Filters, another Parkinson Technologies brand.
Some of the key technology features of the new Model 81 TCU include: graphic-friendly HMI display with recipe storage; simplified calibration and machine-set ups; compatibility with all Dusenbery machines for fast, easy replacement.
