Industrial Current Signal Measurement
Analog current signals are widely used in industrial automation systems to transmit measurement data from sensors and transmitters. Standard 4–20 mA or 0–20 mA signals are particularly common in process control because they provide strong immunity to electrical noise and allow reliable long-distance signal transmission.
The WAGO 750-452 module converts these signals into digital values that PLCs and controllers can process in real time. This enables precise monitoring and control of variables such as pressure, flow, level and temperature within distributed automation systems. :contentReference
