This card is useful for connecting digital systems (such as a 5V microcontroller) to a high-voltage system or "noisy system". This board electrically isolates a controller from the high power system using an opto-isolating integrated circuit.

This integrated circuit has four LEDs and four integrated photodiodes.
This allows the low voltage side to control a high voltage side
We often use this card to allow a microcontroller to control the servos
or other motors that use a higher voltage than the TTL logic on the microphone (3.3 V or 5 V),
and may cause electromagnetic interference with our system when the engines turn on and off.
This board will isolate systems, creating a type of electrical noise barrier between devices
This opto-isolated card uses the TLP281 optoisolant and discrete transistors to correct the logic.
Comes with four channels.
Ideal for noisy circuits where signal lines require electrical isolation
A normal LED opto-isolator will reverse the logic of a signal.
We used transistors on this compact card to correct the inversion.
What you put in the IN pins will be reproduced on the OUT pins, but at the highest voltage (HV)

Characteristics:

Use of high level low level control.
Such as single-chip microcomputer use 3V or 5V voltage 9V or 12V voltage control
HVCC maximum not more than 24V.
The output current of the OUT1 / OUT2 / OUT3 / OUT4 outputs is equal to the largest HVDC / 5.1K,
maximum absorption current 500mA
Input: IN1 / IN2 / IN3 / IN4, SCM or for Arduino IO port,
GND with a single-chip microcomputer or for a GND connection to an Arduino board.
IN1 / IN2 / IN3 / IN4 controls OUT1 / OUT2 / OUT3 / OUT4 outputs respectively
Output: OUT1 / OUT2 / OUT3 / OUT4
Output: HVCC: The connection is the control of the high voltage anode,
HGND connection is the control of the high voltage anode

Card size: 25 * 24mm / 0.98 * 0.94
