TECNOIOT 5pcs TLP281 4 CH Channel Opto isolator IC Module Board Optocoupler Isolation

【TLP281】This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. 【Design compact】 This IC has four LEDs and four photodiodes built-in. This allows the low-voltage side to control a high voltage side. This board allows a microcontroller control servos or other motors that use a higher voltage than the TTL logic on the (3.3V or 5V) micro, and may cause electromagnetic interferance with our system as the motors turn on and off. 【High performance】This board will isolate the systems, creating a type of electrical noise barrier between devices. This breakout board uses the TLP281 optoisolator and discrete transistors to correct the logic.Comes with four channels. Great for use in noisy circuits where signal lines require electrical isolation. 【Easy Operation】A normal LED opto-isolator will invert the logic of a signal. What you put into the IN pins, will be replicated on the the OUT pins, but at the higher voltage (HV) 【Entrega rápida】Envío desde España con llegada rápida a toda la UE
