TLP281 4-way optocoupler isolation module high-low level expansion board electronic building block module
TLP281 4-way optocoupler isolation module high-low level expansion board electronic building block module
1. Function: Use low level to control high level. For example, the use of single-chip computer 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 5. Input/Output Description:
Input end: IN1/IN2/IN3/IN4, connected to the single chip microcomputer or the I/O port of Arduino, GND connected to the single chip microcomputer or the development board of Arduino. IN1/IN2/IN3/IN4 Control OUT1/OUT2/OUT3/OUT4 respectively.
Output: OUT1/OUT2/OUT3/OUT4
Output: HVCC: connects to the controlled high voltage positive terminal, HGND connects to the controlled high voltage negative terminal
Usage: When IN1 is high, the corresponding OUT1 voltage is equal to HVCC, when IN1 is low, the voltage of OUT1 is equal to HGND
