Photo Transistor Coupler is a photoelectric coupler composed of a light-emitting diode and a phototransistor. It uses the photoelectric effect and transistor amplification characteristics to achieve optical isolation and transmission of electrical signals, ensuring stable and reliable signals. Photo Transistor Coupler include two categories: Photo Transistor Coupler (AC) and Photo Transistor Coupler (DC).
