TLP281 4-Channel Optocoupler Module

TLP281 4 Channel Optocoupler Module is designed based on the TLP281 chip, which includes 4 internal optocouplers.

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.

TLP281 4-channel optocoupler board is used in noisy circuits for electrical separation.
