Sinewave dimmer racks and relay modules

We have a SineWave rack that provides power to dimmers in our lobby.  It is the only source of power in a number of places, and it would be useful to have it provide clean power so that we could plug in sensitive electronics like projectors, computers, moving lights and electronic ballast equipment to it.  Is there a way to swap Sine-Wave modules for non-dim modules given the size difference?
