GERUI Pack of 5 1 channel 220 V AC optocoupler module/220 V optocoupler isolation microcontroller/detection of 220 V voltage presence/can be connected to PLCs, TTL level output

Product Features

• Basic: 1 channel optocoupler insulation module, which is mainly used to detect the presence of 220V AC, which is efficient and practical, designed for testing or detection.
• Input and Negative (OUT and GND): The input port is connected to the signal output OUT of this card and the GND on the optocoupler board is connected to the negative electrode of the power supply.
• Suggestions for use: when output to PIC, it is recommended to require up to 5 mA current for external logical circuits. The green 2P 5.0 port is connected to 220 V voltage and the 3P connector is connected to the input of a single chip computer.
• Output: the TTL output level can be detected by a chip computer, 3-5 V power supply, can also be connected to the PLC24V level.
• Easy to use: small and compact, easy to install and replace, has a wide range of applications.
• Attention Do not touch any part of the white wire frame on the board after turning on the module as it is high voltage. Pay attention to power safety.
