Mk139, replacing the relay

What are the dimensions of the relay of this kit and how its pins are arranged? I’m going to change the relay to one which can deal with 230VAC.

Thanks a lot. For you who are searching for a new relay for this kit, RWSH-12V seems to fit, and it’s rated for 230VAC.

You don’t need to change the relay on the kit, it can handle 230 V AC. I connected a 60 W 230V AC light bulb to the relay and it is working just fine.
On the manual it is allowed only 24 V because of the safety reasons but the relay can handle 230 V AC just fine.
