GDU1-C51 series DC voltage transducer is a measurement module that converts the measured DC voltage into a DC current or DC voltage signal with a proportional output of the primary voltage using the principle of optical isolation. The primary and secondary sides are highly isolated, with high accuracy, high linearity, high integration, small volume, simple structure, long-term stable operation and suitable for various working environments. It is widely used in electrical equipment system control and detection in industries such as power, oil, coal, chemical, railway, communication, building automation.
The GDU1-C51 series DC voltage transmitter from Passion Technology converts measured DC voltage into proportional DC current (4‑20 mA, 0‑20 mA) or voltage (0‑5 V, 0‑10 V) signals using optical isolation. It offers high accuracy, linearity, compact size, and robust insulation, making it suitable for power, petrochemical, mining, chemical, railway, communications, and building‑automation applications.
