Doug Fleenor 1211-TB - DMX Isolated Splitter with 1-Input, 11-Outputs and Terminal Blocks with Input Feed-Thru

The DMX512 Isolated Splitter / Amplifier is available in three standard configurations: three, five, or eleven outputs from a single DMX input. Each output is electrically isolated from the input, and from every other output, by 2500 volt optical couplers. Each output has its own line driver and associated power supply.

The DMX splitter allows connection of DMX receivers (dimmers, color changers, moving lights, etc.) in a star configuration as opposed to a daisy chain configuration. In a star configuration, each control cable is run to a central point, in this case the splitter. In a daisy chain configuration all the devices are connected on one control cable, the output of one feeding the input of the next. It is not good practice to simply split a DMX control cable using a "wye" cable as this can cause signal corruption due to reflections. Typical uses of the splitter include splitting the control signal between stage right and stage left dimmers, running an isolated split to a string of color changers, splitting and isolating a feed to a wall outlet for temporary or rented dimmers, isolating a stack of dimmer packs from each other, etc.

Benefits

• Console is protected from failed dimmers, lightning damage, and any other cause of high voltage on the control cable.
• Color changers, moving lights, other dimmers are protected from each other.
• Reflections, short circuits, etc. on one output cannot affect another output.
• Easy "fool proof" installation.
• Assists in proper control wiring.
• Rugged and attractive for years of service.
• Assures reliable connections.
• Eases field service.
• Easily isolates line voltage failures. Usually withstands electrical storm damage.
• Reliable, high speed data throughput. Units can be cascaded.
• Prevents arcing across circuit board.
• Reliably drives long control cables.
• Simplifies system trouble shooting.
