TC920V Nireco | Tension Controller

Thiết bị điều chỉnh lực căng Nireco

The TC920V Tension Controller can be used with a wide range of web manufacturing and treatment processes to automatically control the tension of a moving web to a constant value. Digital calculation allows a wider range of functions than previous products, but the controller can still be operated in the intuitive style of an analog device. This controller combines stable and precise tension control with excellent cost performance.

Feature TC920V Nireco

• Control knobs for frequently-used operations
  Control knobs are used for tension settings and manual settings to give a familiar feel.
• Clear display
  A four-digit LED display is used for quick and easy checking and an LCD display for more extensive information.
• Simple zero and span adjustment on installation
  Automatic adjustment functions make adjustment a simple process. Tension control is conducted with the start contact only. The system automatically outputs pre-output on startup, and slack-prevention output on stop.
• Excellent responsivity and stability
  Proportional and integral action are augmented by our renowned fixed loop gain calculation.
• Connection with a wide range of tension sensors
  Can be connected to the following wide range of Nireco sensors: MB, MG, MC, CD, MJ, CJ, TSA, and intrinsically safe TSA sensors
• Free choice of actuators
  Electromagnetic brakes and clutches, pneumatic brakes and clutches and torque motors can be used.
• Compatible with automatic paper splicing
  The new/old spindle switching signal produces paper splicing preset output for paper splicing with little variability.
• Diameter measurement function
  An encoder or other suitable sensor can be connected to measure roll diameter.

Function TC920V Nireco

Loop Gain Correction Circuit Provides Excellent Responsiveness and Stability

• Tension Signal Converter
  Digitally display the sum or product of the No. 1 and No. 2 tension sensor tensions.
• Control Calculator
  A control calculator compares the tension signal from the tension display with the target tension, and reduces any variation. Additionally, the ever-popular constant loop-gain control delivers superb control stability and responsiveness, regardless of coil diameter.
• Output Amp
  When the magnetic brake/clutch on the final control element is used, the power of the control signal is increased, and output at 0 to 24 V (4A). When the air brake/clutch is used, 4 to 20 mA is output to the electro-pneumatic converter. When a torque motor is used, a 0 to 10 V (2mA) voltage signal is output to the motor driver.
