1/3/8 Circuit 220V AC Optocoupler Module

1-way description:

Function: Can be used to detect the presence of 220V AC power

The output TTL level can be detected by a microcontroller. The power supply can be 3-5 V

It can also be connected to PLC24V level

When connecting to the PLC input terminal, the COM terminal of the PLC is connected to the 24V power supply input terminal and the signal output OUT of this board is connected. The GND on the optocoupler board is connected to the negative pole of the power supply

Green 2P 5.0 terminal connected to 220V voltage

Connect the 3P terminal to the microcontroller input

Board size 73mm X15mm

Safety warning: When practical, do not touch any components inside the white wire frame on the board after this module is powered on Because it is high voltage. Pay attention to electrical safety

3-way description:

1. Function: Test whether AC 220V exists; When there is 220V, the optocoupler can be grounded; Otherwise, there will be no conduction

2. Output high/low levels: can be directly connected to the SCM IO interface for testing, with a voltage of 3-5 V

3. Adapt to connect with PLC, compatible with almost all PLC inputs

4. Board size 72mm X45mm

8-way description:

Function: Test if AC 220V exists

Output TTL level: can be tested using MCU, with a voltage of 3-5 V

Output can be connected to PLC 24V

Wiring:

When connecting the PLC input, the COM terminal of the PLC is connected to a 24V power supply, the input terminal 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 a 220V voltage, and the yellow pin signal output.

When the 220V voltage is normal, output low level; When 220V is powered off, it outputs a high level.

Board size 138mm X56mm

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