DMXOPTO DMX512 In-line Optical Isolator technical data sheet

PublishTime：2024-11-30

●The DMX512 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. The isolator was designed to be economical while providing thousands of volts of protection. The isolator consists of two integrated circuits (a 2500 volt optical coupler and a 60 mA line driver) mounted on two circuit boards (not even the circuit board connects the input to the output). The circuit is enclosed in a metal Switchcraft barrel connector with 5 pin connectors for input and output (a three pin version is also available). The isolated driver is powered by a UL listed wall mount power supply. A signal present indicator is visible through a hole in the barrel to assist in troubleshooting.
●The input circuit of the In-line Optical Isolator does not meet the DMX512 specification with regard to sensitivity or loading of the line. It requires a strong signal (3 volts) and places a heavy load on the line. A true DMX512 circuit requires only 0.5 volts to receive a reliable signal and up to 32 receivers can be placed on one DMX512 output. The In-line Optical Isolator should be the only device the console drives and it should be used within a few feet of the console. The In-line Optical Isolator's input circuit will not work at all if driven by a "slew-rate-limited" output circuit. These newer circuits are not currently used by many manufacturers but may become more common in the future.
