Smoke Factory SF-39004 is the dedicated remote-control printed circuit board for select Smoke Factory fog machines. This board provides the interface for external control methods such as DMX 512, analog 0-10 V remote control (cable or fader), and ensures proper signal processing and control feed-through for the mainboard.
The SF-39004 PCB handles all external control wiring for Smoke Factory fog machines — converting incoming DMX or analog remote signals into commands the mainboard understands (pump activation, fog output percentage, timer, etc.). According to the official service manual for models like Enterprise TC4, the 39004 board is labeled “PCB Remote (DMX and analogue)” and is separate from the main power/control board.
If a fog machine loses remote or DMX control responsiveness — for example, no reaction to DMX commands, analog fader not affecting output, or erratic control — replacing the SF-39004 often restores proper remote control functionality. Because this is a genuine OEM part, compatibility with factory wiring harnesses and firmware logic is guaranteed, reducing risk compared to generic or aftermarket remote-controller boards.
This PCB is valuable for rental houses, touring rigs, stage installations, or any setup where remote/DMX control is critical and reliability under repeated use matters.
