Current Loop to Voltage Converter (4-20mA to 0-3.3V/ 0-5V/ 0-10V)

This module converts an industrial 4-20mA current-loop signal into a voltage signal, bridging current-based industrial transducers with voltage-input data acquisition systems, microcontrollers, or PLCs. Current-loop transmission is preferred in many industrial settings because the signal is far less susceptible to noise and voltage drop over long cable runs than a direct voltage signal from sensors like thermocouples or resistive strain gauges.

The module takes the standard 4-20mA input and produces a selectable voltage output — 0-3.3V, 0-5V, or 0-10V — so it can be matched to whatever input range the downstream device (microcontroller ADC, DAQ card, PLC analog input) expects, without needing a custom signal-conditioning circuit.

Features:
1. Converts 4-20mA current loop to selectable voltage output
2. Selectable output ranges: 0-3.3V, 0-5V, or 0-10V
3. Bridges industrial current-loop transducers with voltage-input devices
4. Improves compatibility with microcontroller ADCs and PLC analog inputs
5. Current-loop input resists noise and voltage drop over long cable runs
