The manual provides specifications, wiring, installation and safety instructions for the Passion Technology 3G‑GDI1‑C52 three‑terminal isolated DC current…
The 3G‑GDI1‑C52 series is a three‑terminal isolated DC current signal transmitter that converts small measured DC currents into proportional DC current or voltage outputs while providing high isolation between primary and secondary sides. It is designed for high accuracy, linearity, compact size and stable long‑term operation, suitable for power, petrochemical, mining, railway, communication and building‑automation applications.
The document includes product introduction, selection information, electrical and general parameters, mechanical and wiring diagrams, output characteristic curves and safety guidelines. It details the available supply voltages, output options, accuracy, response time and environmental limits, and provides step‑by‑step wiring instructions and precautions for safe installation. This manual is written in Chinese.
