Product Features
- TLP281: This board is suitable for connecting digital systems (e.g. a 5V microcontroller) to high voltage or interference systems. It electrically separates the controller from the high-performance system using an optocoupler IC.
- Compact design: this IC has four built-in LEDs and four photo diodes. This allows the low voltage side to control a high voltage side. With this board, a microcontroller can drive servos or other motors that require a higher voltage than the TTL logic of the microcontroller (3.3V or 5V) and can cause electromagnetic interference in our system when the motors are turned on and off.
- High performance: this board isolates the systems and creates a kind of electrical noise barrier between the devices. The breakout board uses the TLP281 optocoupler and discrete transistors for logic correction. It has four channels and is ideal for use in interference-prone circuits where signal lines require electrical isolation.
- Easy to use: a normal LED optocoupler reverses the logic of a signal. What you attach to the IN pins is played on the OUT pins with the higher voltage (HV).
