One DMX console, many relay packs. This 4-channel DMX512 relay controller runs on AC110-220V and gives 4 independent NO relays (5A/ch), switching AC lamps, smoke machines, pumps, fans, and 24V/48V DC loads. The “1 master + N slaves” design lets one master unit broadcast DMX settings while slave packs follow the same show—perfect for multi-zone stages, building façades, KTV rooms, and industrial panels. DMX 0–127 = OFF, 128–255 = ON; DIP switches set start address 1–511. No dimming, no flicker—just safe, isolated on/off power control for non-dimmable equipment. Daisy-chain DMX IN/OUT and scale from 4 channels to 40 with ten packs.
4 Independent Relay Channels – CH1–CH4 = 4 loads; occupy 4 DMX addresses.
Master + Slave / Split Control – One master configures show logic; slave packs sync or take offset DMX addresses for zone control.
AC110-220V Self-Powered – Mains feeds the logic board; no extra 12V/24V control PSU required.
AC + DC Load – AC 5–250V 5A/ch, DC 5–48V 5A/ch (24V pumps/fans/valves OK).
Daisy-Chain DMX – XLR/RJ45 IN-OUT, DIP address, FUN/test mode, relay-isolated output.
