Working Principle:
- The input voltage is sensed by a high-impedance input stage to prevent loading effects.
- The internal signal conditioning circuit scales and linearizes the voltage signal.
- The conditioned signal drives a precision current output stage that generates a corresponding 4–20 mA signal.
- The output current can be transmitted over long distances with minimal signal degradation, as current loops are less susceptible to electrical noise and voltage drops.
Use Cases and Applications:
- Process Control Systems: Converting sensor or controller voltage outputs to current signals for PLC or DCS inputs.
- Industrial Automation: Interfacing analog sensors (e.g., pressure, temperature, level, or flow sensors) with current loop instrumentation.
