1 Channel AC 220V Optocoupler Isolation Module High Voltage Opto Isolator 3-5V Power Supply PLC Photoelectricity Coupler Module. can be used to detect the existence of 220V AC Output at TTL level which can be detected with the help of a microcontroller, the power supply can be 3 to 5V, this module can also access PLC24V level.

Specification:

• Board Size: 73*15mm
• Functuon: Testing whether AC 220V is existed
• Ouput TTL Level: can use SCM to test, voltage is 3-5V
• Adaptive to PLC 24V level

Note: When the power module in the power of the board after the white wire frame can not touch any device because it is high voltage. Note the safety of electricity.

 

Package Included:

• 1 x Optocoupler 1-Channel Isolation Module Voltage Detect Board Compatible with PLC
