Mechanical Design and Installation
The module features a compact 45 mm wide housing suitable for crowded control cabinets. Its DIN-rail mounting simplifies installation and reduces panel space requirements. The lightweight construction weighs only 0.45 kilograms, which minimizes mechanical stress on the mounting rail. All connectors use pluggable terminal blocks for quick wiring and maintenance.
Electrical Performance and Connectivity
This tension controller operates from a 24 V DC supply with a wide tolerance of ±20%. It consumes 15 watts under normal load conditions. The device includes two isolated analog inputs for load cell signals and two analog outputs for actuator control. Four digital inputs accept 24 V DC signals from sensors or pushbuttons. Four digital outputs provide 0.5 A each for driving indicators or contactors. The system supports PROFIBUS DP communication for seamless integration with higher-level PLCs.
Functional Features and Energy Storage
This control module maintains setpoint stability through its internal PID algorithm. It stores configuration parameters in non-volatile EEPROM memory. The built-in energy storage capacitor sustains operation during brief power interruptions. This feature prevents data loss and ensures smooth recovery after voltage dips. The module also offers automatic zero-point calibration for improved measurement accuracy.
Operational Benefits
This tension controller reduces material waste by maintaining consistent web tension across varying line speeds. Its fast response time minimizes web breaks and enhances production efficiency. The diagnostic LED indicators provide real-time status updates for troubleshooting. Users can adjust all parameters via the front panel potentiometers or remote fieldbus.
Application Versatility
This device suits a wide range of web processing machinery. It works effectively in printing presses, laminators, and slitter-rewinders. The module also performs well in coating lines and textile processing equipment. Its robust design ensures reliable operation in harsh industrial environments.
