PLC Connection: To set up, connect the COM terminal to a 24V power supply. Link the input terminal to outputs S1 through S8 on the board, with the optocoupler GND linked to the negative power.
Volt Detection: This feature checks for the of AC 220V. For testing, an MCU can be used, operating within a voltage of 3 to 5 volts.
Level Output: A low is output when the 220V voltage is stable. If the 220V power is disrupted, it triggers a high output.
Working Tips: Ensure the blue 5.0 terminal connects to the 220V voltage, and the yellow pin acts as the output for efficiency.
Good Material: Constructed with PCB for durability, this component is designed to malfunction during long-term use.
