Industrial Current Loop Monitoring
Current loop signals such as 4–20 mA are widely used in industrial automation because they allow reliable long-distance signal transmission and strong immunity to electrical interference. Sensors measuring variables such as pressure, temperature, level and flow typically transmit their measurement values using this standard current signal.
The WAGO 750-454/025-000 converts these analog current signals into digital values that PLCs and automation controllers can process for monitoring, alarms and closed-loop control. This enables accurate process supervision across distributed industrial automation architectures.
Typical Applications
- Monitoring analog signals from industrial transmitters.
- Integration of 4–20 mA process sensors.
- Process automation and instrumentation systems.
- Energy and utility monitoring.
- Industrial manufacturing and machine control.
