1 Channel 220V AC Optocoupler Module Optocoupler Isolation Detection 220V Voltage

1 Channel 220V AC Optocoupler Module

1 Channel 220V AC Optocoupler Module has the capability to identify the TTL level of the output. The power supply can operate at either 3-5V or 24V for PLC input. This input connects to the COM terminal board, and its signal is sent to OUT. To power the optical coupling board, the negative end should be connected to GND, while the positive end should be connected to a blue 2P 5.0 terminal with a 220V voltage input.

The input of the microcontroller is connected to the 3P terminal.

Attention: Please note that the power module, located behind the white wire frame on the power strip, must not come into contact with any equipment due to its high voltage. Please prioritize electrical safety.
