Product Overview

The FMF KTC828A is a full automatic web tension controller for closed-loop tension control systems. It processes feedback from compatible tension sensors and regulates a magnetic powder brake, magnetic powder clutch, inverter, servo, or other compatible actuator to maintain material tension during winding and unwinding.

Key Features

  • 32-bit high-speed CPU with a graphic LCD and Chinese/English display.
  • Adaptive PI control for fast, stable tension regulation.
  • Automatic and manual control modes with dual-station switching.
  • Acceleration and deceleration compensation.
  • Two 24 V / 4 A main outputs and two 0-10 V auxiliary outputs.
  • RS485 communication with Modbus protocol support for compatible PLC or HMI integration.
  • Password protection helps prevent unintended parameter changes.

FAQ

Can the KTC828A directly drive a magnetic powder brake or clutch?

Yes. It provides two 24 V / 4 A main outputs for compatible magnetic powder brakes or clutches.

Does it provide an analog control output?

Yes. Two 0-10 V auxiliary outputs are available for compatible inverters, servos, or electro-pneumatic converters.

What should be confirmed before ordering?

Confirm the tension-sensor signal, required actuator output, brake or clutch current, installation dimensions, and wiring plan.
