PLC 4 Channel Amplifier Board Positive Control Negative Control Optocoupler Isolation
Electrical isolation requirements. Between the A and B circuits, signal transmission is required, but the power level between the two circuits is too great, with hundreds of volts on one path and only a few volts on the other.
Two kinds of huge difference power supply systems, can't share the power, A circuit has connection with strong electricity, human body contact has electric shock danger, need to be isolated.
An optocoupler is an electro-optical-electrical conversion device that transmits electrical signals using light as a medium. It consists of a light source and a light receiver. The light source and the light receiver are assembled in the same sealed housing, separated from each other by a transparent insulator.
The pin of the light source is the input end, and the pin of the light receiver is the output end. The common light source is the light emitting diode, the light receiver is the photodiode, the phototransistor and the like.
