Taco SR504-EXP-4 Need Help Hooking Nest E To C Wire.

Hello, I had the Argo AR861 Switching Relay and I noticed it did not have a c wire so I couldn't connect the nest thermostat for the c wire. So I purchased the Taco SR504-EXP-4 to get the c wire to work for 2 thermostats. I am confused on what I need now to power the thermostats. Do I need external transformer or do I need a rib-u1c relay to power it? Is the internal transformer enough to power 2 or just 1 thermostat? I have the 3 zones.
