ماژول اپتوکوپلر 4 کانالTLP281 ، بر پایه تراشه TLP281 طراحی شده است و این تراشه شامل 4 اپتوکوپلر داخلیست.
این اپتوکوپلر 4 کانال در مدارات پرنویز برای جدایی الکتریکی به کار میرود.
Description: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.
