DMX Optical Isolator

The DMX512 Inline Optical Isolator is DESIGNED TO PLUG DIRECTLY INTO THE BACK OF MOST DMX LIGHTING CONSOLES. Its primary purpose is to protect the console from hazardous voltages, which may appear on the control cable. Some causes of hazardous voltages include dimmer failures, electrical storms, and cross wiring non-DMX equipment (foggers, intercoms, arc welders) into lighting control outlets. The isolator also eliminates ground loops and provides high drive current for long control runs. 5-PIN ONLY

DMX Isolation Amplifiers
The DMX512 Isolation Amplifier is recommended for the receiving end of long control runs. It contains separate input and output power supplies, allowing the input circuitry to receive signals as low as 0.2 volts.

The model 121D and 121Q contain the same isolation and protection circuitry used in model 121, but have multiple isolators in a single enclosure. They are ideally suited for use with control consoles which have multiple DMX outputs. The Model 121D has two isolators and the 121Q has four isolators. Both models are available with either 3 pin or 5 pin connectors, specify at time of order.

DMX Isolated Splitters
The DMX Isolated Splitter / Amplifier allows you to split a single DMX512 dimmer signal into three, five or eleven optically isolated DMX512 signals. Optical isolation creates a physical break between the DMX512 links to help prevent accidental high voltage from damaging equipment on the DMX512data stream. Available with either 3 pin or 5 pin XLR connectors. 550-100.jpg

DMX Enhanced Isolated Splitter - Wall Mount
This Enhanced Splitter has all of the features of Fleenor's standard splitters plus a universal power supply, input and output protection, and troubleshooting indicators, all packaged in a purpose built housing for permanent installation. DMX512 connections are via plug-in terminal blocks and the AC power connection is via an attached 6' power cord with a standard U-Ground plug. UL Listed and CE marked. 125EE.jpg

DMX Bidirectional Hub
The DMX Hub offers isolation and signal buffering for bidirectional communication. The hub differs from an opto-splitter in that any of the eight ports can receive data, with the seven remaining ports re-transmitting that data. Each of the eight ports offers fully bidirectional optical isolation and transient protection to 15,000 volts. Includes a universal power supply and gold plated connectors. bidi8.jpg

DMX Rotor-Router
The DMX Rotor-Router is an electronic patch bay for DMX512 signals. Consisting of an Input Module with twelve inputs and any number of Output Modules with twelve outputs each, the unit patches any input to any output using front panel rotary switches. The inputs and outputs are all electrically isolated to prevent ground loops and fault propagation.

DMX A/B Switches
This series of selector switches was specifically designed to switch DMX512 signals. Originally designed to switch between primary and backup consoles, these switches are often used to select from two (or more) input locations. Model SW1 switches a single DMX512 universe (one A input, one B input, one output). Model SW4 switches four DMX512 universes (four A inputs, four B inputs, four outputs). swfam.jpg

DMX Combine Units
Want to pile-on two DMX512 sources? You can't just tie the outputs together like you can with 0 to 10 volt analog control signals. Combining two DMX512 sources requires a computer, like the one in these units. The combiner introduces the minimum delay possible with DMX512, less than 0.02 seconds. Combine units are available in up to six input configurations. For more than 6 inputs, multiple units can be linked together. These combiners feature terminated opto-isolated inputs which are also protected from AC line crosses and transients. Each input has an LED signal indicator. These combiners can also be used to convert to or from Colortran's CMX protocol (as used in D-192 series dimmers). Available with 3-pin or 5-pin XLR connectors 221e-621e.jpg

Wall Plates
The DMX512 Wall Plate is a single-gang "switch box" cover milled from solid aluminum. Fitted with either a male or female 5-pin XLR connector, the plate is available in black anodized. Nomenclature is permanently milled into the faceplate. The rear of the wall plate features screw terminals for easy field wiring.

Wall plates can be either passive or active. Passive wall plates would be wired back to a splitter, merger, or rotor-router. Active wall plates include buffer circuitry which allows more advanced distribution methods.

DMX Relay Packs
Doug Fleenor Design makes a series of Relay Packs that are controlled by DMX512.

The single channel unit, designed to switch up to a 20 amp line voltage load, uses a 30 amp relay. The unit is provided with two 18" 12/3 SJ pigtails for line in and switched line out. Supplied with 15 amp parallel blade connectors as standard.

The six channel units, designed to switch up to 15 amp line voltage loads, use 30 amp relays. Line voltage input is on 18" 12/3 SJ pigtail(s) fitted with 15 amp parallel blade plug(s). Model DMX6REL15A has one line in pigtail. Model DMX6REL30A has two line in pigtails (one for channels 1-3, one for channels 4-6). Switched line outputs are on chassis mounted 15 amp parallel blade receptacles.

DMX512 control of low voltage switch closure devices (such as slide projectors and fog machines) is made possible with low voltage DMX Relay Packs.

Available with 3-pin or 5-pin XLR connectors.
