Stephen Swaffer:
I am a licensed electrician-but my church contracted a building (I didn't bid as I have a different day job right now.)  Unfortunately, the master that designed the building installed 8 amp rated 0-10 volt dimmers on 13 amp zones in the gym-obviously they didn't last long.  Ultimately our goal was to convert and allow the dimming to be incorporated into a DMX system for events.  Given I need to replace a dimmer and really hate how much garbage they stuffed into the box  the time to make it like we want is now.  I know Northlight made interfaces-they are no longer around so what is the best way?  I will likely convert the existing box to switches, there is a path to get dimmer lines to a utility room just need the DMX interface.

I don't think there is anything compatible between an analog (dimmers) and digital (DMX).  They make DMX dimmer packs that will control incandescents, but not the  other way around. You'll need power at the fixtures, and a DMX cable to daisy chain control.

Brian Jojade:
Are you looking for JUST DMX control, or local control PLUS the ability for DMX control?  The latter is a more complex scenario.

The Doug Fleenor stuff is the best for this.  A little pricier than what you see kicking around on Ebay/amazon but much more enterprise-grade and well supported.

Although check with the manufacturer of your architectural dimming panel, they may have a DMX add-on module available as well as some have capability already on the control board but with headers just labelled to whatever proprietary name they call it.

Erik Jerde:
If Iím understanding you right it sounds like you need to replace dimmers and thatís also an opportunity to replace the user controls.

In that case use whatever dimmer will fit your form factor and interface with DMX.  If you have to stick with a 0-10v control then the fleenor stuff is the way to go.

I admittedly have very little experience with 0-10v architectural products.  The one project I was on where this was used the dimmer was actually part of each fixture.  The wall control was powered by mains but the control to fixture run was a special MC cable that had mains conductors and a pair of LV conductors for the dimming control.
