Photo and product description
1.功能：使用低电平控制高电平。比如使用单片机的3V或5V电压控制9V或者12v电压。
2.HVCC不要超过24V。输出口OUT1/OUT2/OUT3/OUT4输出电流等于HVCC/5.1K，吸收电流500ma。
3.本模块采用东芝TLP281芯片5.输入输出说明：
输入端：IN1/IN2/IN3/IN4，接单片机或者Arduino的IO口，GND与单片机或者Arduino开发板的GND连接。IN1/IN2/IN3/IN4分别控制OUT1/OUT2/OUT3/OUT4。
输出端：OUT1/OUT2/OUT3/OUT4
输出端: HVCC：连接被控制的高电压正极，HGND连接被控制的高电压负极
使用：当IN1为高电平时，相应的OUT1的电压等于HVCC，当IN1为低电平，时，OUT1的电压等于HGND
