t's not possible to convert the Dark Energy's into a module or to install the device into the Eurorack. The distances between the knobs and switches are different and the Dark Energy's pcb boards do not fit into the Eurorack. For the Dark Energy's the vertical distances between the knobs is 25 mm, for the A-111-5 these distances were 20 mm. A-111-5 was the modular version of the Dark Energy 1 and was equipped with smaller knobs. It's out of production because of the obsolete CEM3394 since many years.
