DMX512 / MIDI / ASCII -> Demultiplexer for 12 analog channels and extensions
The DAC12A is a DMX512, ASCII and MIDI control able 12 channel analogous 0-10V Demultiplexer. A single output can source or sink up to 50mA. The minimum output voltage is approx. 0.012V (12mV).
Since first issue in the year 1997 as a 4 channel version the circuit grows and got better continuously. Dimensions, mounting, fastening and handling stays nearly the same.
The latest issue - the D-revision – now has beside good old functions some new ones like a higher output current of 200 instead 50mA, a mains supply overvoltage protection, an zero voltage offset compensation of the 0-10V outputs to nearly 0V (12mV), a weight reduction from 280g onto 105g only and as well as a mains supply voltage range from 100 to 240V~.
All electrical circuits (ICs) for receiving DMX512 and for the output voltages are mounted in sockets for easy exchange.
