Product Description
| Product Overview The module can control high voltage levels using low voltage levels, for example, using a 3V or 5V microcontroller voltage to control a 9V or 12V voltage. The HVCC voltage should not exceed 24V. Outputs DOUT1/OUT2/OUT3/OUT4 have an output current equal to HVCC/5.1kΩ and a sink current of 500mA. The module uses the original TLP281 chip. |
| Input/Output Description: Input terminals: IN1/IN2/IN3/IN4, connect to the I0 port of a microcontroller or ForArduino. GND is connected to the GND of the microcontroller or ForArduino development board. IN1/IN2/IN3/IN4 control OUT1/OUT2/OUT3/OUT4 respectively. Output terminals: OUT1/OUT2/OUT3/OUT4 HVCC: Connect to the positive terminal of the controlled high voltage. HGND: Connect to the negative terminal of the controlled high voltage. Usage: When IN1 is high, the corresponding voltage of OUT1 is equal to HVCC. When IN1 is low, the voltage of OUT1 is equal to HGND. |
| Instructions The following example demonstrates how to use a microcontroller's IO to control a 24V motor. In the figure, the motor's operating voltage is 24V. The red "+" indicates the positive terminal of the motor's power supply, and the black "-" indicates the negative terminal. When the microcontroller's IO_0 output is low, the motor rotates. When the IO_0 output is high, the motor stops. |
