Safety note: The mains (L/N) and relay output (NO/COM) connections are safety-critical; only authorized technical personnel connect them, according to the wiring diagram. The relay rating is resistive; compatibility with inductive pump models is verified with the technical team. Price, MOQ, lead time and certification details are shared at the quotation stage.
If my phone isn't with me, does the machine keep running?
Yes. The schedule and clock are on the board (RTC + non-volatile memory); the app is only for setup and monitoring. The weekly schedule runs uninterrupted even when no phone is connected.
Which platforms does the app run on?
Android, iOS and Web (Chrome/Edge, Web Bluetooth). Download and details: marg.com.tr/scent.
Is this product a complete scent machine?
No. MARG SCENT is an electronic control board (PCBA + firmware + mobile app) for scent machine manufacturers and integrators. We do not sell scent cartridges, fragrance oil or finished devices.
Does the board run on 220 V, is an adapter needed?
Yes, the mains input (220–240 V AC) is fed by the board’s built-in, EMI-filtered AC-DC module; no external adapter is needed. The mains connection must be made only by authorized technical personnel, according to the wiring diagram.
What is the output, how many pumps does it drive?
A single 10 A relay output (TIANBO HJR-3FF-S-Z; 10 A/120 VAC, 7 A/240 VAC resistive) drives one pump/motor from the screw MOTOR terminal. There is no second output, SSR or triac. Compatibility with inductive pump models is verified with the technical team.
How does the weekly schedule work?
The days of the week are selected active/inactive one by one; the start/stop time is common to all active days (e.g. Monday–Friday active, 08:00–18:00). Within the window, the spray/wait cycle is set in 5-second steps (e.g. spray 45 s, wait 15 min).
What happens if the power goes out?
Thanks to the RTC and CR2025 backup battery, the clock and calendar are preserved; settings are held in non-volatile memory. When power returns, the schedule resumes where it left off. A hardware watchdog (~4 s) automatically restarts the board on any lockup.
Is there a phone app, is internet required?
On V2 and V3, the ‘Scent Program’ app runs on Android, iOS and Web (marg.com.tr/scent). The connection is short-range Bluetooth LE, PIN-protected; no internet or Wi-Fi is required. Every change is written to the board instantly — there is no separate ‘write to board’ step.
What are the price, minimum order and lead time?
Price, MOQ and lead time are shared in a quote based on version, quantity and OEM scope. For a sample, reach us via the contact page with your pump model, annual quantity and preferred version.
Do you offer OEM / brand-specific customization?
Yes. The splash-screen brand text, panel layout (faceplate fit), app branding/PIN policy, connector and cable set can be customized. Scope, quantity and NRE are quoted after a technical assessment.
