Current to Voltage Module 4-20mA/0-20mA to 0-3.3V/0-5V/0-10V Signal Conversion Module محول تيار الى جهد

This Current to Voltage Module converts industrial current loop signals into corresponding voltage outputs for direct use with microcontrollers, data acquisition systems, and analog inputs. It is designed to be placed at the receiving end of a current transmission line so the robust current signal—less affected by voltage drop over long distances—can be translated into a stable voltage signal for testing and measurement.

• Current input ranges supported: 0–20 mA and 4–20 mA.
• Voltage output options: 0–3.3 V, 0–5 V, and 0–10 V.
• High-precision current sampling resistor: color-ring resistors with low drift and high power rating for reliable, repeatable conversion.
• Purpose-built for end-of-line current-to-voltage conversion to facilitate single-chip testing and interfacing with standard ADC inputs.

By converting current loop signals to voltage, this module allows long-distance sensor or transmitter signals to be transmitted as current to minimize attenuation and electromagnetic interference, then converted back to voltage where needed for measurement or control. The device is appropriate for applications where isolation from transmission losses and accurate analog representation are required, and where a clean, proportional voltage output is needed for further processing.

Installation and wiring should follow standard current-loop and analog input practices to ensure correct polarity and range selection. The module offers a practical solution for integrating 4–20 mA or 0–20 mA sensors with 3.3 V, 5 V, or 10 V analog systems using a robust, precision sampling resistor design.
