dry contact k868 a8m

hi,
i'm trying to connect some solenoid valve to the board .
the solenoid use 24vac, when i connect the cable of the solenoid valve to the output 1, it goes on.
i don't undestand why

take a photo, how you wire. A8M output DC voltage, but you are using AC solenid, how it works?

i connect the 24 dc to the power of the board,
then i connect one wire from the 24ac to the first pin and the second to the solenoid valve.
like i connect the other board with standard relay

No, it's wrong. you should connect a extend relay to control AC load (solenoid valve)

then i have to move to k868 a8?.
but i don't understand why if it is a dry contact it can't use the vac

A8 is relay , it's dry contact. A8M is MOSFET output, it work with DC voltage, not work for AC.
