Function: Use the low level to control the high level. Such as the use of single-chip 3V or 5V voltage control 9V or 12v voltage.         2. HVCC should not exceed 24V. Output OUT1 \/ OUT2 \/ OUT3 \/ OUT4 output current equal to HVCC \/ 5.1K, absorption current 500ma.         3. This module uses TLP281 chip (for?Toshiba).         4.

Input: IN1 \/ IN2 \/ IN3 \/ IN4, then the microcontroller or IO port, GND and the development board connected to the GND.   \u003cbr\u003e IN1 \/ IN2 \/ IN3 \/ IN4 controls OUT1 \/ OUT2 \/ OUT3 \/ OUT4, respectively.         Output: OUT1 \/ OUT2 \/ OUT3 \/ OUT4         Output: HVCC: Connect the controlled high voltage positive, HGND connected to the controlled high voltage negative         Use: When IN1 is high, the corresponding OUT1 voltage is equal to HVCC, when IN1 is low, the OUT1 voltage is equal to HGND     \u003cbr\u003e   \u003cbr\u003e   \u003cbr\u003e   \u003cbr\u003e       \u003cstrong\u003eUse examples\u003c\/strong\u003e         ?
