Tension Controller

This tension controller provides precision control over both unwinding and rewinding in web and strand processing applications. Its unique control system eliminates common application problems, such as feathering, breaking, wrinkling or blocking. While the standard tension controller is provided with a dual 4–20-mA output and Ethernet TCP/IP interface, optional network interfaces are also available, including Allen Bradley Remote I/O, DeviceNet, Profibus, ControlNet, and Modbus TCP. Other features incorporated in the device include: WAVERSAVER‚ which ignores machine vibration to provide an accurate signal; C2 electronic calibration, which calibrates without the use of test weights; and Secure Memory Module (SMM), which automatically backs up configuration data.
