In ETAP, you can connect multiple CTs to each relay, if that particular relay has multiple inputs/functions.
Model the relay by manufacturer and type. Model the two CTs (make sure you click 'Ground' under 'Type' on each CT editor), then attached each CT to the relay as you would any other device. Go to the 'Input' page of the relay editor and designate which CT is for which input.

Many ways to do it.
