CA8402B（4 Channel DMX signal distributor，DMX512，RS-485 interface）
4 Channel DMX Signal Distributor
Product Overview
This is a DMX512 signal distributor that reshapes and amplifies DMX512 data signals. The power supply for each input and output interface is independent, adopting high-voltage isolation technology. It is suitable for extending the transmission distance of DMX512 signals, enhancing signal strength, increasing the number of fixtures connected to the console, and applications that require electrical isolation between the console and fixtures, as well as between fixtures.
Key Features
-
Full Electrical Isolation: Each input and output channel is equipped with an independent power supply and opto-isolation, achieving complete electrical isolation between channels to avoid signal interference and ensure stable transmission.
-
Comprehensive Protection: All interfaces are provided with over-current, over-voltage and ESD protection circuits, effectively protecting the equipment and connected lighting fixtures from circuit damage, prolonging service life and improving operational safety.
-
Convenient Wiring Design: The power supply interface adopts a one-in one-out design, which is highly user-friendly for on-site wiring, installation and commissioning, saving construction time and reducing operation difficulty.
