Description
Product Description
1 way description: 1. Board size: 73 * 15mm 2. Punctuation: test whether AC 220V exists 3. Output TTL level: SCM can be used for testing, the voltage is 3-5V 4. Suitable for PLC 24V level product description: The microcontroller can detect the output TTL level. The power supply can be 3-5V Can also access PLC24V level Then the PLC input terminal COM COM power supply 24V input terminal board signal output OUT, the optical coupling board GND power supply negative The blue 2P 5.0 terminal is connected to 220V voltage The 3P terminal is connected to the microcontroller input. safety warning: When the power supply module is behind the white wire frame on the power supply board, you cannot touch any equipment because it is high voltage. Pay attention to the safety of electricity.
