Isolated Analog Control with Potentiometer

This is an Isolated Potentiometer Module that integrades an LOC110 linear optocoupler, isolated DC-DC converter, an onboard 10K linear potentiometer, and supporting circuitry. This module is designed for reliable operation in VFD drives, process control, PLCs, automation, and other industrial applications where safe analog signal isolation is required.

Thanks to the onboard isolated DC-DC converter, the module operates from a single 5V DC supply, simplifying integration. With full rotation of the potentiometer, the output provides a 0–3.3V DC isolated analog signal, completely isolated from the potentiometer input.
