Description: The new enhanced version of the 3-way 220V optocoupler isolation module has greatly improved the drive capability of the previous generation module. The NPN transistor output has a saturation conduction current of up to 100-300MA, which can be connected to any single-chip microcomputer or PLC. Function: Can be used to detect the presence of 220V AC. When the 220V is used, the optocoupler is turned to the ground. No 220V is not conducting. Output high and low level can be directly connected to the microcontroller IO port detection. Power supply can be 3-5V It is also possible to connect all PLC inputs to the PLC. The card guide can be used with the PLC bracket to guide the rail. Package include: 5 * 3 Channel AC 220V Optocoupler Isolation Board
