LX200V20 vs LX200V30 Zero-crossing

Hello community!

I was doing some research on the LX200V20 and LX200V30 Power Line Communication (PLC) modules.
One major difference I found was the lack of a Zero Crossing input on the LX200V30. Is it still possible to use this module if I have to work with AC signals or should I use the LX200V20 module instead?

Hi,

Sorry,Both LX200V20 and LX200V30 don’t have a Zero Crossing input.

Then why does the datasheet of the LX200V20 says there is a ZC input?
