Smoke Factory SF-39143 | PCB Mainboard TC4 / Data II | OEM Control Board Replacement

Main Control PCB for Fog Machine

Smoke Factory SF-39143 is the original mainboard (printed circuit board) used in Smoke Factory's high‑power TC4 and Data II fog machines. This board manages the machine’s digital controls including fluid pumps, heating, DMX/remote control, fan output (if fitted), and safety cut‑offs — ensuring correct operation and reliable output.

Smoke Factory SF-39143 Competitive Differences

• Genuine OEM part — guaranteed by Smoke Factory for full compatibility with TC4 / Data II internal wiring and control systems.
• Replaces the full mainboard unit — ideal for restoring older machines or repairing units with PCB failure, restoring factory‑spec control and safety functions.

Smoke Factory SF-39143 Description

The SF‑39143 PCB is the “brain” of TC4 and Data II fog machines. With its digital control architecture, it enables the versatile feature set of these machines — including pump/fan output regulation, DMX 512 compatibility, timer or stand‑alone operation, fluid output control (from 1% to 99%), and automated temperature management to maintain safe, reliable fog generation.

When a TC4/Data II experiences faults such as erratic fog output, heater/pump failures, or loss of DMX/remote responsiveness, replacing the mainboard with SF‑39143 restores the original control logic — often resolving control‑related issues at once. Because it is a factory original, you get proper fitment, correct firmware/electronics behavior, and compliance with Smoke Factory's design standards.

This makes SF‑39143 an essential spare for rental houses, touring rigs, or any user who needs to maintain uptime and reliability — especially in professional show environments.
