4-20 mA Converter

The 4-20 mA signal converter is used to integrate the unit with a 4-20 mA transmitter. The 4-20 mA technology is used to communicate analog signals over long distances where electrical interference is a problem. This solution is often used in the process control industry to collect the analog values from a wide array of remote sensors. Current signals are much less susceptible to noise than voltage signals. A voltage signal can be converted to current and broadcast over a long distance before it is converted back to voltage and read by the unit.

4-20 mA transmitters are common in the industry and used with high-quality sensors. The 4-20 mA converters can now be integrated into the unit and can be enhanced by adding graphing, web interface, email interface, thresholds and limits.
