4. Functionality
The SCBoxT functions as an input expansion module for the SC24 data acquisition system. It collects analog signals from up to 16 temperature sensors—thermocouples or Pt100 RTDs—and transmits the conditioned, compensated data to the SC24 main unit for processing, logging, and control.

Working Principle:
- Each input channel receives a low-level signal from a connected sensor.
- For thermocouples, the SCBoxT measures the voltage difference generated by the thermoelectric effect and applies cold junction compensation to correct for ambient terminal temperature.
- For Pt100 sensors, the module measures resistance changes corresponding to temperature variations.
- The module’s internal electronics convert these analog signals into digital data, which is then communicated to the SC24 system via a dedicated interface.
- The SC24 system interprets, displays, and records the temperature data, enabling real-time monitoring and control.

Use Cases and Applications:
- Industrial process monitoring and control
- Laboratory temperature measurement setups
- Environmental testing chambers
- Manufacturing quality assurance systems
- Research and development instrumentation
- Multi-point temperature profiling in furnaces, kilns, or reactors
- HVAC and building automation systems requiring distributed temperature sensing

Compatibility:
- Fully compatible with the SC24 system architecture
