2-Port Isolated DMX/RDM Splitter

DS 2

Two-port DMX/RDM splitter for permanent installations. The DSX2 takes one DMX/RDM input and splits it across two optically isolated outputs, so a fault on one line leaves the other running. A passive Thru port carries the input on to further devices, and full RDM support lets you address and monitor fixtures remotely.

  • Outputs 2× isolated DMX / RDM
  • Isolation Optical
  • Power 100–277 V AC, 50/60 Hz
  • Mounting 35 mm DIN rail

Common questions, answered.

It takes a single DMX/RDM input and delivers two independent, optically isolated outputs, so a fault on one line won’t affect the other.
Yes. The control protocol is DMX-512 / RDM, and full RDM support lets fixtures be addressed and monitored remotely.
A dedicated Thru port passes the input signal on to further devices. It is a passive loop-through.
It runs directly from 100–277 V AC mains, 50/60 Hz.
It mounts on 35 mm DIN rail in a black powder-coated sheet-metal housing measuring 165 × 88.5 × 76.5 mm (L × W × H).
It is rated IP20 and carries the CE mark.
It operates from −20°C to +60°C (−4°F to 140°F) and can be stored from −20°C to +70°C (−4°F to 158°F).
