PCF type automatic equipment

Micro deviation automatic tension controller PCF-120A This controller detects the material tension using load detectors arranged at the both ends of the roll, controlling the powder clutch/brake and AC motor's torque by making the set tension and the detected tension equal. This technique yields the highest precision compared to our other tension control methods, maintaining exactly the tension you specified. It also features microcomputer control, with a ten key input method and an intuitive interface, making for a truly multi- function tension control system. |

Features
| High precision microcomputer control
This equipment uses a 16bit microcomputer to calculate the exact torque requirements with minimal operational error. Additionally, the load detector uses a load cell to reduce the detection error to a minimum.
| Simple operation
Troublesome dial adjustments are abandoned in favor of a numerical keypad, providing exact input.
• Operating values such as initial zero, span setting, tension setting and response gain can be digitally input, allowing consistency across similar machines.
• The set tension and detected tension are separately displayed and the tension can be changed even during a line stop.
| Small and lightweight
By adopting microcomputer control and by using a switching power supply, the equipment is smaller and lighter, eliminating the need for reinforcing angles when mounting on the wall or on a panel.
| Sophisticated Controls
• The output voltage is automatically stored when the power is shut off, and is immediately set when power is restored, allowing a quick, effortless recovery from power failure.
• A DC value of 0-10V can be input to specify the external tension.
• A DC value of 0-10V is output to indicate external tension.
• In addition to a DC 24V signal, an analog 10V output is provided, allowing for a wide range of control.
• An overcurrent protection circuit is provided to protect the controller in case of a power failure.
• Internal failures can be detected automatically with integrated diagnostics.
