Amp draw on the Prop-1 for the Crydom D2W203F?

First off, let me say that reading this forum (Especially all the time Jon spends answering questions) has given me a good headstart before my Prop-1 and relays arrive next week. If I didn't do a good enough search, just give me a hint on the proper search wording....

I noticed some of the threads on the amp draw on the DC relays that they could easily exceed the 500ma range, but on the DC controlled AC relays, the avg. draw is stated at 3ma for the control. Is this about were the load stays as far as the ULN is concerned since the DC is just the "switch"?

If this is the case, then running 6 or so relays shouldn't be an issue as far as load on the Prop-1? (all AC)

I'm looking to do some light sequencing for the logo of our cover band and then eventually pick up an FC-4 and try some fades, etc.

Thanks,
Ron

You are correct -- the input side of the Crydom relay is an LED circuit that doesn't draw a lot of current; the output side is never seen by the Prop-1 so it doesn't care.
