The circuit board has Relays installed, and the power connections and DMX connections are all screw terminals.</div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif">The reason I am not simply using a dimmer pack set to serve as on/off only mode, is that I have both 120v and 12vDC voltages. The 12vDC will be to trigger sprinkler valves that are part of two air-cannons. The 120v will be to power a miniature xenon strobe. Though, perhaps I can use a standard dimmer pack, and just plug 12vDC power supplies for the two channels I need the DC control. I am a little concerned that the inductive relays on the water valves may not play well with my 12v wall warts. I suppose some diodes at the solenoid may solve that.</div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif"><br></div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif">Note that the DMX, 3-channel Relay module I have, has screw terminals for all in/outputs.</div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif"><br></div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif">When I have made a similar custom pack in the past. I obtained some XLR Panel connectors. But, drilling the holes in the box was both frustrating and not really good enough, even if I got it to function. I looked for, but didn't find any generic pre-punched panels to attach the two XLR connectors. Though, I did find ones with 4 or 8 locations.</div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif">Also, the box has to provide for the 120vAC, and 12vDC in/out. In the past, I just used cut extension cords, with a strain relief. The 12v was easy, just a circular panel mount outlet.</div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif"><br></div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif">I feel I am somehow not finding the right stuff to do this easily, and professional looking.</div><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif"><br></div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif">As I wright this, I think I am convincing myself to just use a standard DMX dimmer pack.

Perhaps in the form factor of a power strip? I know heavy-weight often means rugged. But there is also a kind of ruggedness that comes with things that are small and light weight.</div><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif"><br></div><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif"><div style="font-family:Helvetica,Arial,sans-serif;font-size:16px"><div dir="ltr" style="font-family:Helvetica,Arial,sans-serif;font-size:16px">-Joe</div></div></div></div></div></div>____________________________________________________________<br>
