Product Name:110V/220V AC Voltage Detection Household Grid Power-on/Power-off Reminder Module for Arduino pi PLC STM32 ESP8266
 

Packing list:
1 PCS 1CH AC 110V/220V to 3.3V 5V 12V 24V Detection module
 
 
 
 
Description:
 
This is a one-channel AC110-220V optocoupler detection module, which can detect whether there is electricity in the household wire network.The 3-24V level signal output by the module can be recognized by the ARM microcontroller PLC.

Product specification
Detected voltage: AC110V/220V
Output level: 3-8V/9-24V two versions
Output signal type: NPN/PNP
Output signal current: 3-8V version 1-3MA; 9-24V version 2-5MA
Isolation voltage: 3000V
Signal frequency: <5KHz
Working temperature: -40-110 degrees Celsius
Size: 72*17*18MM
Weight: 11.6 grams

Function:
Detect whether there is input to AC220V(AC110V), and output high and low levels (NPN output)

USE:
When there is 220V input, the LED light is on, and the OUT port outputs low level
When there is no 220V input, the LED light is off, and the OUT port outputs high level

Note: The L N terminal and the device in the white box are high voltage! Be careful when using it!
