ROPEX® RESISTRON® RES-420

Impulse Sealing Controller – Panel Mounted

This ROPEX Resistron temperature controller is an integral part of the "Series 400", the outstanding feature of which is its microprocessor technology. All Resistron temperature controllers are used to control the temperature of heating elements (heatsealing bands, beaded bands, cutting wires, heatsealing blades, solder elements etc.), as required in a variety of heatsealing processes. The controller is most commonly used for impulse heatsealing PE films in:

Resistron RES-420
Vertical and horizontal f/f/s machines
Pouch, filling and sealing machines
Film wrapping machines
Pouch-making machines
Group packaging machines
L-sealers

The use of Resistron temperature controllers results in:

Repeatable quality of the impulse heat seals under any conditions
Increased machine capacity
Extended life of the heatsealing bands and PTFE coatings
Simple operation and control of the sealing process

Description of the Controller

The microprocessor technology endows the Resistron temperature controller RES-420 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 0.4V 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.

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.

The real heatsealing band temperature is visualized on the display both as a digital number in °C and in the form of a dynamic bar.

The Resistron temperature controller RES-420 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 24VDC 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 (TOSS Alloy-20®, NOREX etc.) and set the required temperature range (0…300°C, 0…500°C etc.).

The Resistron temperature controller RES-420 is designed for installation in a front panel cutout. The compact design and the plug-in connections make this controller easy to install.
