PC817 4-Channel Optocoupler Module

PC817 4 Channel Optocoupler Module is composed of 4 PC817 chips, which have 24V maximum trigger input and 30V maximum output.

Optocouplers consist of a LED and an optical transistor, and when the input of the optocoupler is triggered, the internal LED of the optocoupler turns on and activates the optical transistor, and as a result, the two output pins of the optocoupler (which are the emitter and collector pins of the optical transistor) are connected.

PC817 4 Channel Optocoupler Board is used in noisy circuits for electrical separation.
