A linear optical coupler is an optoelectronic device that couples an input voltage signal to an output while maintaining electrical isolation. It typically consists of an infrared LED optically coupled to two photodiodes: a feedback photodiode and an output photodiode. The feedback photodiode forms a servo loop that adjusts the LED drive current to compensate for nonlinearities and temperature variations, ensuring the output signal is linearly proportional to the input voltage .
A Linear Optical Coupler Voltage Acquisition Module provides a reliable method to measure low-level AC or DC voltages in environments with high common-mode noise or hazardous voltages. By combining servo-controlled linear optocouplers with appropriate amplifier circuits, these modules achieve high linearity, wide bandwidth, and robust galvanic isolation, making them ideal for industrial, medical, and power electronics applications.
