4-20mA To 0-5V Signal Isolated Converter Module – Current/Voltage Transmitter

Working on an industrial control system or Arduino project?

This little module converts 4-20mA current loops into a clean 0-5V output with full isolation.

That means less noise, safer connections, and accurate readings for your sensors or PLC inputs.

It’s an unbranded generic board, but the specs are solid—perfect for hobbyists, electricians, or automation techs who need a reliable signal interface.

The board is compact and easy to wire up, with clearly marked terminals.

Made in China and sold as a bare module, so you’ll need to handle mounting and enclosure yourself.

Great for retrofitting old equipment, building custom instrumentation, or integrating sensors with microcontrollers.

Whether you're monitoring pressure, temperature, or flow, this converter bridges the gap between current loops and voltage inputs without breaking the bank.
