Many sensors for measuring temperature, pressure, and solar radiation have analog interfaces. DMA801 and DMA802 provide analog channels and convert the analog data into digital format for DMU801.
The analog inputs support Pt100, Pt1000, NTC thermistor, and voltage‑out sensors such as pyranometers.
Each analog measurement module includes:
- 4 differential analog channels
- 2 additional single‑ended high voltage channels
- 2 counter measurement channels
In addition, DMA802 has 2 frequency channels.
Depending on the size of DMU801, it is possible to add up to 8 analog measurement modules to DMU801.
