Interactive Technologies offers a family of ultra-compact 8 Port DMX512 splitters. The portable IT-SP8R is designed for use in installations wired with RJ45 terminated Category 5 (CAT5) cabling. The DIN Rail mounted IT-SP8D is designed for use in permanent installations.

The DMX Splitter is designed to create multiple independent branches of a DMX signal and/or to extend the usable distance of each branch. Each of the splitter’s 8 output ports generates an independently protected DMX signal that can travel up to 1,800 feet (550 meters).

Both the IT-SP8R and IT-SP8D include a DMX Pass-Thru port for cascading DMX to multiple splitters and provide a built-in DMX Termination switch. The IT-SP8R features a Polarity Inversion switch which allows for easy conversion between DMX512 standard wiring and the reversed wiring used by Color Kinetics® devices.

We proudly design, engineer and manufacture our DMX Splitters in the USA.
