A87 4 roads opto-isolation module high-low level expansion board
A87 4 roads opto-isolation module high-low level expansion board
- This board is useful for connecting digital systems to noisy or high-voltage equipment, such as a 5V microcontroller.
- Using an opto-isolator integrated circuit (IC), this board electrically isolates a controller from the high-power system.
- This integrated circuit contains four LEDs and four photodiodes. As a result, a high voltage side can be controlled by the low voltage side.
Features and Specifications:
- Use of low level control high level. Such as the use of single chip microcomputer 3V or 5V voltage 9V or 12V voltage control.
- HVCC maximum not more than 24V.
- Outlet OUT1 / OUT2 / OUT3 / OUT4 output current is equal to the largest HVCC / 5.1K.
- Maximum absorption current 500mA.
- Input: IN1 / IN2 / IN3 / IN4, SCM or for Ard uino IO port, GND with single-chip microcomputer or for Ard uino board GND connection.
- IN1 / IN2 / IN3 / IN4 respectively control the OUT1 / OUT2 / OUT3 / OUT4.
- Output: OUT1 / OUT2 / OUT3 / OUT4
- Output: HVCC: Connection is control of high voltage anode,
- HGND connection is control of high voltage anode
- PCB Size: 25*24mm/0.98*0.94
