Tension Controller TC680A/D

Tension Controller TC680A/D


This analog tension controller was designed for easy-to-use, safe control and ease of operation. This intuitive controller, with its simple functionality, is easy for anyone to use.


Tension Controller TC680A/D
  • Excellent Responsiveness via Constant Loop Gain Circuit

    The control circuit uses Proportional + Integral calculation, providing fast response and high accuracy. Additionally indexed calculation is used to maintain a constant loop gain, regardless of changes in diameter. This maintains high responsiveness without hunting, maintaining appropriate loop gain at all times.

  • Easy to Use and Operate

    The unit can be controlled automatically as long as you have an automatic machine contact. Consequently, the controller is easy for anyone to use, as long as a tension value is set. When stopped, a sequence allows the stopped output value corresponding to the diameter to be obtained.

  • Tension Display

    It is possible to find the total tension, as well as the tension on just one side. Select an analog or digital display to suit your preferences.

  • Wide Range of Applications

    Fits the final control elements of a large number of applications, including air brakes/clutches, air motors, electro-magnetic brakes/clutches, torque motors, and magnetic coupling motors. Select the installation method to suit the location, from panel-mounted, stand-alone, or mounted.

  • 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
