Product Introduction:




1 way 220V AC optocoupler detection module
Function: can be used to detect the presence of 220V AC
The output TTL level can be detected by a single chip microcomputer. The power supply can be 3-5V
Can also be connected to PLC24V level
When connecting to the PLC input terminal, the PLC's COM terminal is connected to the power supply 24V input terminal is connected to the signal output OUT of this board, and the GND on the optocoupler board is connected to the negative electrode of the power supply.
Blue 2P 5.0 terminal connected to 220V voltage
The 3P terminal is connected to the MCU input.
safety warning:
In practical use, after the module is powered on, do not touch any components in the white wire frame on the board.. Because it is high voltage. Pay attention to the safety of electricity.
