Features & Benefits
- EASY: universal interfaces help simplify setup, commissioning and integration into new or existing process and building automation systems.
- SAFE: the two-component product approach separates the functional module from the junction box, supporting practical maintenance and continuous protection principles.
- SMART: intelligent sensor/control combinations can recognise compatible sensors automatically, reducing product variants and stocking complexity.
- Hazardous-area Ex families and industrial NC families allow the same control philosophy to be applied across classified and non-classified projects.
- German development and manufacture with regional partner support for selection, documentation and after-sales service.
Applications
- Hazardous-area HVAC and ventilation controls
- Damper actuation and volume-flow control
- Temperature, humidity and pressure monitoring
- Pharmaceutical, chemical, offshore, oil and gas facilities
