KTC628A / KTC628AV
Product Image
Product Introduction
KTC628A is a torque tension controller, while KTC628AV is a speed-synchronized tension controller. Both use tension-sensor feedback and PI control for roll-to-roll equipment, with an LCD-and-dial operating interface. Select the model according to whether the machine requires torque-based tension regulation or speed synchronization with tension correction.
Key Features
- Graphic LCD with Chinese/English display, adjustment dial and automatic/manual switching
- PI control with configurable proportional and integral settings
- Left, right or combined tension-sensor input with selectable ±30mV / ±300mV range
- Zero and span calibration, with kg or N display units
- Parameter password protection, backup and restore
- 110–240VAC supply range. Specify the actual supply voltage when ordering so the power configuration can be customized accordingly.
- RS485 Modbus RTU communication; confirm the fitted communication option when ordering
KTC628A or KTC628AV?
KTC628A — Torque tension controller
KTC628A regulates material tension through torque control using tension-sensor feedback. It is intended for torque-based unwind/rewind applications, with settings for A/B shaft changeover, starting and stopping compensation, and rewind taper tension. Confirm the matched actuator and output configuration when ordering.
KTC628AV — Speed-synchronized tension controller
The KTC628AV parameter set emphasizes following a master speed reference while applying tension correction. Settings include an electronic gear ratio, speed-dependent start threshold, correction-gain limits and low-tension compensation. Review this version for inverter or servo speed-synchronization applications.
Confirm the exact hardware/firmware revision, sensor excitation, analog-output range, communication option and any external power amplifier before ordering or replacement. A shared enclosure does not establish electrical interchangeability.
