Function and Working Principle
The ASI133-S00/SA3S0 module measures resistance changes from RTD sensors or potentiometers and converts them into digital values for the control system.
For RTDs, resistance changes according to temperature, enabling accurate thermal measurement. For potentiometers, resistance variation represents mechanical position or displacement.
The module performs signal conditioning and analog-to-digital conversion internally, ensuring stable operation even in electrically noisy industrial environments.
This enables:
- Accurate temperature measurement from RTDs
- Position feedback from potentiometers
- Stable resistance-to-digital conversion
- Real-time data acquisition for control systems
- Reliable operation in harsh industrial environments
