Ok, each one needs 15-20mA Driver Current. still too much for the pi to handle.
It looks like it drives opto's,

I did a lookup what the pi can handle: the maximum you can source from all the GPIO outputs simultaneously is less than 50 mA.
4 times 15 mA for four relays means 60 mA, and we didn't considder the pi itself that also uses gpio for several stuff.
