PC817 4 Channel Optocoupler Isolation Module
An Optocoupler, is an electronic component that interconnects two separate electrical circuits by means of a light sensitive optical interface.
There is a is a light emitting diode with a phototransistor inside the optocouplers, both of them are isolated from the external environment of the optocoupler; This means that the internal phototransistor can only receive light emitted by the internal light emitting diode.The phototransistor base is stimulated by light received from a light emitting diode and can pass current according to it. Onboard with 4-Channel 817 are independent, so they can achieve different voltage control at the same time.
Technical Specification:
- No. of Channels: 4
- Input Voltage: 3.6-24V
- Output Voltage: 3.6-30V
- Size: 47.3mm*37.7mm*1mm (L*W*H)
Features:
- Jumper switches output from high to low
- All four channels are independent and can be used with different voltages at the same time
Applications:
- Can be used when we want the control circuit (for example, processors) to be separate from the power circuit (for example, relays, motors, etc.) we use optocoupler to remove the power circuit noise on control circuit
