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 SKU: N/A Categories: Electronic Componets, Sensor
