A/D D/A conversion boards

A/D and D/A boards allow the communication of the PCs with analogous devices. A/D boards in particular serve the digitalization, measurement and visualization of tensions and courses of events. D/A boards in turn move digital signals into analogous ones.

Description:

A signal connected to the analogous entry of the card is moved into a 8, 10, 12 or digital signal board more bit by means of analogue-to-digital converters. The data outputs are read out and manufactured by the arithmetician in a routine.
Recording of changing signals hangs before all things of maximal that sampling rate of the transformer off. The more often a signal is sampled within a period, it is the more precisely reproducible. In order to avoid mistake the sampling rate should twice at least be so high as the maximum frequency of the analog signal. (Example: CD-Player 44,1kHz). Important is, always with that least possible measuring range to work (see also Aufloesung). A D/A board goes away for the turned around ones: She reads data of the data bus of the arithmetician and moves this into analog values. Within a specific field, a tension can become like this or spend a river. (Example: Sound card).
Our A/D and D/A boards can unipolar both and bipolar switched will can, that is, they either a field of zero up to a defaulted value register and/or spend or else in the bipolar company, measure or make both positive and negative tensions and rivers. In addition, we also provide with multi-purpose boards, that both one at/through- and a D/A part have.


Usage:

A/D and D/A boards above all find their effort in process control, process control of measured values therefore time-critical during the recording and evaluation from long-term measurements but too during recording, in the case of measurements in the lab and in the case of measurements with special temporal handicaps, those must be read in especially fast and which must be read in in the case of the simultaneous recording of measured values and date of the measurement. In combination, the cards are suitable for the arrangement of task executions and process automation everywhere where one must react flexibly to external conditions in the process. We offer the MFB51 board as a Allround board, the 16 at/through- and four D/A channels at each twelve bits of solution, 24 TTL-I/Os and a programmable input amplifier with up to 100-fold strengthening united. By the booster, measurements too in the millivolt field and the connection of a temperature sensor are possible.
