as noted by above posters, the PI input/output (I/O) is 3.3V
if it were me, i'd look for a 3.3V version of the relay board.
(i have seen some before, just not sure if they were 8 relays)
--- just re-read your post. you were gifted the board. in that case, the above post about using a transistor , etc. would be the way to go.
