Switch three real loads from one DMX address block. This 3-channel DMX512 relay board runs on AC110-220V and gives 3 independent normally-open relays, each 5A—handling AC lamps, fog machines, signage, water pumps, 24V fans, and solenoid valves. DMX value 0–127 = OFF, 128–255 = ON, so any DMX console, tester, or pixel controller with DMX out can hard-switch non-dimmable equipment. DIP1–DIP9 set start address 1–511; DIP10(FUN)=OFF for DMX mode, FUN=ON for built-in self-run chase/test modes. Relay isolation keeps DMX logic safe from load side. No dimming, no flicker—just isolated on/off power control.
3 Independent Relay Channels – Occupy 3 DMX addresses (CH / CH+1 / CH+2); map to 3 separate loads.
AC110-220V Self-Powered – Mains feeds the board; no extra 12V/24V control PSU needed.
AC + DC Load – AC5-250V 5A/ch, DC5-48V 5A/ch (24V industrial/smart-home loads OK).
DIP Address + FUN Mode – DIP1–9 = DMX start address; DIP10 = DMX / self-test chase mode.
Isolated ON/OFF – Normally-open contacts, silver alloy; perfect for non-dimmable 220V/24V gear.
