4 Channel Optocoupler Isolation Module 4-Channel Opto-isolator IC Expansion Board High And Low Level For Arduino | Электронные

1. function: use low level control high level. Such as the use single-chip microcomputer 3V or 5V voltage control 9V or 12V voltage.

2. HVCC maximum not more than 24V. Output port OUT1/OUT2/OUT3/OUT4 maximum output current is equal to HVCC/5.1K, the maximum absorption current is 500ma.

3. this module uses TLP281 chip

4. Schematic diagram:

Input: IN1/IN2/IN3/IN4,connect single chip or for Arduino's  IO port,GND connect with GND of for  Arduino development board.IN1/IN2/IN3/IN4 control OUT1/OUT2/OUT3/OUT4.

Output: OUT1/OUT2/OUT3/OUT4

Output terminal: HVCC: connect high voltage positive electrode be controlled,HGND connect  high voltage negative be controlled

Use: when IN1 is high, the voltage of the corresponding OUT1 is equal to HVCC, and when IN1 is low, the voltage of OUT1 is equal to HGND
