Tips: What are the benefits of using a DC current output for voltage sensor?

The voltage sensor’s DC current output (either 4-20mA or 0-20mA) is highly compatible with industrial control systems, PLCs (programmable logic controllers), and SCADA (supervisory control and data acquisition) systems. These systems often rely on current loop signals for monitoring and control, and the DC current output from this sensor provides a linear and scalable method of transmitting voltage information. This output type is immune to long-distance signal degradation, which is a common issue with voltage signals, ensuring that accurate data is transmitted over extended distances.
