8 Channel 220V AC Optocoupler Isolation Module for PLC

8 Channel AC 220V Optocoupler Isolation Module High Voltage Opto Isolator 3-5V Power Supply PLC Photoelectricity Coupler Module. can be used to detect the existence of 220V AC Output at TTL level which can be detected with the help of a microcontroller. The power supply can be 3 to 5V. This module can also access PLC24V level.

Connections :
When connecting the PLC input, the COM terminal of the PLC is connected to the 24V power supply, the input end is connected to the signal output S1-S8 of the board, and the optocoupler GND is connected to the negative pole of the power supply. The blue 5.0 terminal is connected to 220V voltage, and the yellow pin is signal output. When the 220V voltage is normal, the output is low level; when the 220V power is off, the output is high level.

Notice:

After the module is powered on, do not touch any part of the white wire frame on the board, because it is high voltage. Pay attention to electrical safety.
