HL-DMA-RDM — 12–48 V 4-way DMX512 / RDM signal splitter

Use this when one DMX or RDM line must feed four isolated spurs. One optically isolated input, a DMX thru, and four optically isolated outputs (isolated from each other). RDM stays bidirectional. 12–48 V DC, 0.17 A class. Screw terminals and 3-pin XLR on every port. It does not decode DMX into LED output.

Why installers buy it

  • Four independent isolated outs plus thru. Up to 32 devices per out, with a terminator on the last fixture of each spur.
  • Six LEDs: power, signal in, signal out.
  • IP20, about 260 × 112 × 43 mm, 750 g. Rack / surface lugs.

What you are wiring

  • Power in 12–48 V DC (screw or DC socket)
  • DMX/RDM in and thru (terminate thru if unused)
  • DMX/RDM out 1–4, screw or XLR

Terminator 90–120 Ω at the end of each used spur. Unused outs do not need a terminator. The user manual PDF is on the Attachments tab.
