The Enterprise episode "Bound" establishes Human contact with the Deltans as early as 2141. "Star Trek: Star Charts" claim the Deltans became warp capable in 2223 and joined the Federation in the same year. 

Following the Deltans becoming full members of the Federation in 2259 Starfleet teams were assigned to Delta IV. The Deltan Ilia worked closely with these teams and formed a strong attachment to the Human Willard Decker. The two later served together briefly on the USS Enterprise before both were reported "missing in action" after the Enterprise encountered the V'Ger when it approached Earth in 2272. (Star Trek: The Motion Picture)

The Project: Genesis research team assigned to Space Station Regula I was made up of two Deltans; Jedda Adzhin-Dall and his mate, Zinaida in 2284. (TOS novelization: Star Trek II: The Wrath of Khan) 

In 2141, the ECS Horizon encountered a group of Deltans. Travis Mayweather, who was fifteen at the time, later described them as very attractive and very open. His method of dealing with the feelings they engendered in him was exhaustive workouts in the gym, a method he returned to (and recommended to Lt. Malcolm Reed) while three Orion slave girls were "guests" aboard Enterprise. (ENT: "Bound")

A Deltan served as an officer aboard the USS Excelsior in 2285. (Star Trek III: The Search for Spock) A male Deltan ambassador served on the Federation Council in the same year. (Star Trek IV: The Voyage Home)
