Feature
Function:Test whether AC220V exists
Output TTL Level:can use MCU to test, voltage is 3-5V
Output can connect PLC 24V
Wiring
When connecting the PLC input, the PLC’s COM terminal is connected to the 24V power supply, the input is connected to signal outputs S1-S8 of the board, optocoupler GND is connected to the power supply negative.
Blue 5.0 terminal is connected to 220V voltage, yellow pin signal output.
When the 220V voltage is normal, it output low level; when 220V is powered off, it output a high level.
Note
Do not touch any part of the white wireframe on the board after the module is powered on, because it is high voltage. Pay attention to electricity safety.
Package includes
1 x Optocoupler Isolation Voltage Test Board
Weight | 0.054 kg |
