3-Channel AC 220V Optocoupler Isolation Module - AC Detection & Testing Module
Special Features
- 3 Channel 220V optocoupler isolation module, using NPN transistor to output saturated conduction current up to 100-300MA
- The module can be used to detect the presence of 220V AC power
- When there is 220V, the coupling conduction output is low level
- When there is no 220V, Output is a stable high and low level
- It can be directly connected to the IO port of the microcontroller for detection, or it can be connected to a PLC compatible with all PLC inputs
Description
Product parameter
The output power supply can be DC: 3V~24V
Note:
Do not touch any devices inside the white wire frame on the board after this module is powered on Pay attention to electricity safety
