Air carrier First Officer reported on climb out receiving multiple ECAM messages resulting in the flight crew returning to the departure airport.

Narrative

On the climb out from ZZZ we experienced multiple ECAM messages. The Captain (PF) continued flying as I (PM) worked on the ECAM. As soon as I cleared the first ECAM message; all the other ECAMs went away and everything was back to normal. A few seconds later more ECAM messages popped up and which included a CB (Circuit Breaker) in the avionics bay; a fuel feed; (and 2 other fuel related ECAMs) which cleared in about 5-10 seconds before I could go through them. About 30 seconds later; we got other ECAM failures SDAC2 (System Data Acquisition Concentrator) fault and another avionics CB related ECAM. We worked on the ECAMs and at this point knew there might be a bigger problem with the aircraft than what we are seeing. The Captain and I were not concerned about the aircraft status and we decided to contact Maintenance Control and explain what we were experiencing. At this time the Captain handed the aircraft and got in touch with Dispatch and Maintenance Control and collectively deemed it necessary to return to ZZZ. We briefed ourselves on the plan to return information ATC; FAs (Flight Attendants) and passengers of the situation. ATC vectored us back to ZZZ and we returned to ZZZ. We arrived at the gate and were met with multiple maintenance personnel. Dispatch and crew scheduling called us and check on us then later released us from duty.
