More info

4-Channel Optocoupler Isolator Module TLP281 is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or a noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has four LEDs and four photodiodes built-in. This board will isolate the systems, creating a type of electrical noise barrier between devices and this board uses the TLP281 optoisolator and discrete transistors to correct the logic. This board can be used in heavy- noise environments like motor driving application to isolate the signal between the driver and the microcontroller. Maximum voltage is 24V.

Features:

  • Use of low level control high level
  • Such as the use of single chip microcomputer 3V or 5V voltage 9V or 12V voltage control
  • HVCC maximum not more than 24V
  • Outlet OUT1 / OUT2 / OUT3 / OUT4 output current is equal to the largest HVCC / 5.1K
  • Maximum absorption current 500mA
  • Maximum Voltage 24V

How to use:

  • Input: IN1 / IN2 / IN3 / IN4, then the microcontroller or Arduino IO port, GND and the Arduino 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.
