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
