Re: [LCtalk] Is this a viable set up

[Carl Byrne]

This looks more logical to me. I agree that there are numerous ways to get 
to the end result. Regarding the choice between a solids state relay (as in 
the Chavaute box I suggested) and an actual relay box such as Jon suggested 
there are several factors to consider. Money is usually at the top of the 
list, what the budget can afford. In your particular application, I think 
the relays will be switched fairly frequently.  Depending upon how long this 
display is intended to last before a repair is required, a solid state relay 
may serve you better in the long run.

Have you worked out the electronic interface between the DMX signal and the 
variable speed pump? That should be interesting..
