VMB4RY Door bell

I would like to use a relay channel to drive my doorbeel a 4.5v based one solenoid plus a beel.
The relay module is attached to mains on three channe and the 4.5 volt system on the 4’th channel.
Is it OK to do so.
In other words are the isolation internally in the VMB4TY sufficient.

Yes, that is not a problem
