skip introduction and move to features, modifications and ordering information...

The ROPEX Resistron 400 Series of controllers utilize microprocessor technology for sensorless, closed-loop control of impulse heating elements. ROPEX controllers offer a range of configurations and protocols for simple plug-in system integration.

The use of ROPEX Resistron controls goes beyond impulse heat sealers, form fill machines, and converting equipment. ROPEX Resistron controllers also provide a solution for an extensive range of heating applications:

• Heat-seal-bands and cutting-wires ... for hermetic sealing, and trimming of flexible films

• Zebra and intermittent heat-seal-bands ... for skip seals and packaging ventilation

• Impulse heating tools ... for activation of adhesives used in the bonding of non-thermoplastic materials

• Flexible or rigid impulse blades ... for scoring, cutting, and bending of thermoplastics

• Impulse heater coils ... for hot air bonding, and scoring of thermoplastics

• 2D and 3D contour heat-seal-elements ... for custom shaped heat-sealing, and heat-seal plus cuttings

ROPEX Resistron RES-445 controller is at home in a diverse array of industries:

• Aerospace
• Automotive
• Cosmetics
• Chemical
• Dental
• Defense and Military
• Electronics
• Energy and Renewable Energy
• Food and Beverage
• General Industrial
• Healthcare and Hygiene
• Laboratory and Research
• Medical
• Pharmaceutical

The microprocessor technology endows the Ropex Resistron RES445 RES Heat Seal Temperature Controller with previously unattainable capabilities:

• Very simple operation thanks to AUTOCAL, the automatic zero calibration function.

• Good dynamic response of the control system thanks to AUTOTUNE, which adapts automatically to the controlled system.

• High precision thanks to further improved control accuracy and linearization of the heatsealing band characteristic.

• High flexibility: The AUTORANGE function (as of software revision 100) covers a secondary voltage range from 0.4 V to 120V and a current range from 30A to 500A.

• Automatic adjustment to the line frequency in the range from 47Hz to 63Hz.

• Increased protection against dangerous conditions, such as overheating of the heatsealing band.

A time control (timer) function integrated in the controller enables the complete heatsealing process to be controlled on simple machines, such as table heatsealing tools. A Configurable relay output can be used to drive motors, energize magnets, etc.

The process data is represented on an LC display with 4 lines and 20 characters. Devices with a VF display are available as an option. Various display languages can be selected.

In addition to the digital and bar indications on the display, the ACTUAL temperature of the heatsealing band is supplied to an electrically isolated, analog 0 ... 10VDC output. The real heatsealing band temperature can thus be displayed on an external temperature meter (e.g. ATR-x).

The Ropex RES-445 Resistron Temperature Controller also features an integrated fault diagnosis function, which tests both the external system (heatsealing band, wiring etc.) and the internal electronics and outputs a selective error message in case of a fault

To increase operational safety and interference immunity, all 24 VDC logic signals are electrically isolated from the controller and the heating circuit.

The menu in the temperature controller itself can be used to adapt to different heatsealing band alloys (Alloy-20, Low-Ex etc.) and set the required temperature range (0 ... 300°C, 0 ... 500°C, etc.).

The Ropex RES-445 Resistron Temperature Controller is designed for installation in a front panel cutout. The compact design and the plug-in connections make this controller an ease to install.
