โมดูลตรวจสอบไฟ AC 220V AC optocoupler module 220V optocoupler isolation detection 220V voltage can be connected to PLC [ 1Way /3Way ]


ใช้สำหรับตรวจสอบไฟ AC220V ว่าเปิดอยู่หรือไม่ ด้วยระบบ Optocoupler ทำให้ปลอดภัยไม่เกิดไฟย้อนเข้าระบบควบคุมแน่นอน 

Output เป็น Low เมื่อไฟฝั่ง AC มีแรงดัน
Output เป็น High เมื่อไฟฝั่ง AC ไม่มีแรงดัน(วงจรเปิด)

ตัวอย่างวิดิโอการใช้งาน



1 way 220V AC optocoupler detection module

Function: It can be used to detect the existence of 220V alternating current

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

Can also be connected to PLC24V level

When connecting the PLC input terminal, the PLC COM terminal is connected to the power supply 24V input terminal is connected to the signal output OUT of this board, and 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

The 3P terminal is connected to the MCU input.

Board size 73mm X15mm 

safety warning:

In practical use, do not touch any components in the white wire frame of the board after the module is powered on.. Because it is high voltage. Pay attention to the safety of electricity.

 

--------------------------------------------

 

3-way description:

1. Function: Test whether the AC 220V exists; when there is 220V, the optocoupler can be grounded; otherwise, it will not conduct
2. Output high/low level: It can be directly connected to the SCM IO interface for testing, and the voltage is 3-5V
3. Adapt to PLC connection, compatible with almost all PLC inputs
