24ch DMX to 0-10v Controller Theatrelight

Theatrelight’s updated 24 channel optically isolated DMX to Analogue receiverallows control of analogue devices such as 10 volt dimming fluorescent ballasts, LED luminares, or older analoguedimmers from any DMX controller. The receiver may also be used for controlling via optocouplers motors and otherdevices from DMX. The receiver is built in the same housing as Theatrelight’s popular SP4 DMX splitter, allowing easyfixing to lighting bars and walls, while being small enough to house inside other equipment.DMX InputThe DMX-512 input is optically isolated to 250 vac and presents only 1/10th normal RS485 load to the DMX line. Theinput and through DMX connectors are XLR 5 pin Neutrix as standard. Other connectors including 3 pin can also besupplied.DMX Address selectionThe DMX start address can be set by the front panel thumbwheel switch, allowing the receiver to output any 24 DMXchannels from 1 to 512. The address range is limited so DMX channel 512 appears on analogue output 24.DMX controlled outputsA four way dipswitch on the front panel selects preset output voltages of +5, 6, 7.5, or 10 volts. Access to a calibrationpotentiometer on the front panel allows changes of –1% to +20% to the standard output levels. The maximum outputcurrent for any single channel is 10 milliamps; the total current for all channels should be limited to 50 milliamps. Outputimpedance is 500 ohms, short-circuit proof. Out of range DMX start addresses set all outputs at zero.Output response timeOutputs respond to a change in the DMX signal within one DMX packet time (~25 msecs). Output rise and fall timesafter receipt of a DMX packet are 100usec (10-90%).Output connectionsA 25D male connector provides convenient connection such as ribbon cable to the analogue outputs. The outputs withtheir zero reference may float at up to 50 vac above mains earth to prevent earth loops with older analogue dimmers. Themetal shell of the 25D connector is connected to mains earth.LED indicatorsTwo front panel LEDs are provided to indicate power and DMX status. Both LEDs green shows correct operation.Power LED Green Control power OKDMX LED Green DMX connected OKGreen flash DMX connected but thumbwheel setting out of rangeGreen/Flash Red DMX connected, DMX errorsRed DMX not presentDMX Fail behaviourOn DMX controller switch-off or other failure of the DMX signal, the Receiver holds its outputs at the last receivedDMX levels for 5 minutes, then fades all outputs to zero over 5 minutes.ElectronicsFlash microprocessor. The circuitry uses long-life 105 degree rated capacitors.Power supply and connector110- 120 or 220-240 VAC, 50/60 Hz, set at time of order. Power consumption is less than 10 watts. The mains cable is 1metre long, fitted with 3 pin Australia/NZ plug. Other connectors available at time of order.ConstructionBlack epoxy powder coat over zinc plated steel case.
