Description: 1. 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. Schematic:
Input and output instructions: ? Input: IN1 / IN2 / IN3 / IN4, then the microcontroller or IO port, GND and the development board connected to the GND.
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
Use examples ? The following example shows how to use the microcontroller's IO port to control the 24V motor rotation. Figure motor operating voltage of 24V,
red + that the motor power positive, black - that the motor power supply negative. When the microcontroller IO_0 output high, the motor rotate,
when the IO_0 port output low, the motor stops rotating.
