PL-SPL DIN4 is a DIN-mountable, multi-input/output DMX splitter designed to handle up to two DMX universe inputs and four independent DMX outputs, increasing the number of devices managed from 32 to a total of 4 × 32 by splitting the signal into four separate output channels.

Two operating modes are configurable via an onboard manual switch: single universe mode distributes one DMX input to all four outputs, while dual universe mode splits two inputs into two independent 2 × 2 configurations.

Output terminals are optically isolated from the inputs to ensure signal integrity and prevent electrical interference — while sharing a common ground reference for compatibility with connected devices.

Features

• Up to 2 DMX universe inputs and 4 independent DMX output channels — expand from 32 to 4 × 32 devices.
• Two operating modes via onboard manual switch — single universe (1 → 4) or dual universe (2 × 2).
• Optically isolated outputs — signal integrity and protection from electrical interference or damage.
• Common ground reference across outputs — maintains compatibility with connected devices.
• DIN-rail mountable compact housing — 3-pin connector blocks for all data input and output.
• Robust design for reliability and performance in demanding environments.
