What describes the signal distortion produced by current outputs over long distances?

The signal distortion produced by current outputs over long distances is considered low. This is primarily due to the nature of current loop signals, such as the 4-20 mA standard commonly used in industrial settings.

When transmitting signals over long distances, current outputs maintain a constant current level, which is less susceptible to voltage drops and interference from electromagnetic noise compared to voltage outputs. This results in a more stable signal, enabling accurate measurements and control even at extended distances.

The low distortion characteristic of current signals means they can reliably transmit data without significant degradation, making them ideal for applications requiring high accuracy in measurements across long runs of wiring. In contrast, other signal types may experience higher levels of degradation due to resistance in the wiring or external interference, impacting overall system performance and data fidelity.
