1-Bit AC 220V Optocoupler Isolation Module Voltage Detect Board Adaptive 3-5V For PLC Isolamento Fotoaccoppiatore Module

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 Features: - Output TTL level can be detected with the microcontroller. The power supply can be 3-5V - Can also access PLC24V level - Then the PLC input terminal of the PLC COM power supply 24V input termination of the board signal output OUT, optocoupler board GND power negative - Blue 2P 5.0 terminal connected to 220V voltage - 3P terminal connected to the microcontroller input. Safety Warning: 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 1-Bit AC 220V Optocoupler Isolation Module
