Product Introduction:
Output TTL level can be detected with the microcontroller. The power supply can be 3-5V
Can also access PLC24V level
Then the PLC input terminal of the PLC COM power supply 24V input termination of the board signal output OUT, optocoupler board GND power negative
Blue 2P 5.0 terminal connected to 220V voltage
3P terminal connected to the microcontroller input.
Safety warning:
When the power module in the power of the board after the white wire frame can not touch any device .. because it is high voltage. Note the safety of electricity.


Feature:
Functuon: Test whether AC 220V is existed
Ouput TTL Level: can use MCU to test,voltage is 3-5V
Output can connect PLC 24V
Wiring:
When connecting the PLC input, the PLC's COM terminal is connected to the 24V power supply, the input is connected to signal outputs S1-S8 of the board, optocoupler GND is connected to the power supply negative.
Blue 5.0 terminal is connected to 220V voltage, yellow pin signal output.
When the 220V voltage is normal, it output low level; when 220V is powered off, it output high level.
Note:
Do not touch any part of the white wire frame on the board after the module is powered on, because it is high voltage. Pay attention to electricity safety.
