Tension & Winding Control
TC818
Tension Controller
The TC818 tension controller is used for constant web-tension control on unwinding and winding lines. The main output can drive magnetic powder clutches or brakes directly, with auxiliary analog outputs and communication options.
Technical Detail
Technical Details
The TC818 tension controller is used for roll-diameter and automatic constant-tension control systems. It supports magnetic powder clutch or brake drive outputs, auxiliary analog outputs and optional RS232/RS485 communication.
It is suitable for winding, unwinding, printing, paper converting and other lines that require stable web tension and coordinated speed control.
