Look under BASIC>RELAY There are a bunch there. The last four numbers indicate the amperage, form and voltage i.e EDR2H1A05. is Form A (N.O.) 5VDC relay. I think the number before the "A" in the example mean that it is a 1 amp relay.
I hope this helps some. I believe my fact to be correct, but I have been known to make mistakes. One thing that I am sure of is the last 2 digits do represent the voltage value.
