## Description

3Pcs 1Channel AC Optocoupler Module 220V Voltage Detect Optocoupler Isolation Microcontroller TTL Level 3V-5V

## Features

- 1 Channel 220V AC optocoupler module can be used to detect the presence or absence of 220V AC power
- The output TTL level can be detected by a microcontroller, stabilizing the output of high and low levels (NPN output)
- When detecting 220V input, the LED light is on, and the optocoupler is conducting and outputting a low level
- When there is no 220V input, the LED light does not light up, the optocoupler is not connected, and the output is pulled high by a resistor
- The output power supply can be DC: 3V~24V, or it can be connected to a PLC 24V level
