DMX Optical Input Splitter PCB is 1 input 4 output DMX 512 splitter (distributor, buffer, amplifier, or booster) with OPTICAL ISOLATION on the input offering potentially higher voltage protection. Field serviceable: socketed IC's for easy replacement, standard IC's available from many electronic parts suppliers, replaceable power supply, standard 5 x 20mm internal fuse.

NOTE - In order to optically isolate the input and offer protection, the DSI-4 requires a 25mA input line load which is ½ of a DMX 512 daisy chain load. It is recommended this unit be used directly out of the lighting board or DMX generating device. Because of this load the input does not conform to the DMX 512 specifications but should work with most systems. For more information about DMX 512 visit DMX512 Standards.

Also note that the 4 outputs are separately driven and electronically isolated, not optically isolated from each other.
