A87 4 Channel Optocoupler Isolation Module High And Low Level Expansion Board

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 orIO port GND and thedevelopment board connected to the GND IN1 IN2 IN3 IN4 controls OUT1 OUT2 OUT3 OUT4 respectively Output OUT1 OUT2 OUT3 OUT4Output HVCC Connect the controlled high voltage positive HGND connected to the controlled high voltage negativeUse When IN1 is high the corresponding OUT1 voltage is equal to HVCC when IN1 is low the OUT1 voltage is equal to HGNDUse examples The following example shows how to use the microcontrollers 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 Package included 1 x A87 4 Channel Optocoupler Isolation Module
