Figure motor operating voltage of 24V, red ' ' that the motor power positive, black '-' that the motor power supply negative

Function Use the low level to control the high level

HVCC should not exceed 24V

IN1 / IN2 / IN3 / IN4 controls OUT1 / OUT2 / OUT3 / OUT4, respectively

Output OUT1 / OUT2 / OUT3 / OUT4 output current equal to HVCC / 5.1K, absorption current 500ma

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

Package included 10 x A87 4 Channel Optocoupler Isolation Module

Schematic Input and output instructions Input IN1 / IN2 / IN3 / IN4, then the microcontroller or Arduino IO port, GND and the Arduino development board connected to the GND

Such as the use of single-chip 3V or 5V voltage control 9V or 12v voltage

This module uses TLP281 chip for Toshiba

When the microcontroller IO 0 output high, the motor rotate, when the IO 0 port output low, the motor stops rotating
