Many control applications require D/A conversion to provide the control signals for the actuators. The DS210x D/A boards provide various channel numbers, resolutions, and speeds for you to choose from.
D/A conversion is required by many rapid control prototyping applications to provide the control signal for actuators. In the other direction, in hardware-in-the-loop applications, sensors that provide analog signals have to be simulated.
The D/A boards provide various channel numbers, resolutions, and speeds for you to choose from. The following table gives you an initial overview. All three boards can be configured from Simulink® with Real-Time Interface. You can select the voltage range for each channel individually.
Board | Channels | Resolution | Sample Time 2) |
---|---|---|---|
DS2101 D/A Board | 5 out | 12 bit | 3.0 μs |
DS2102 High-Resolution D/A Board | 6 out | 16 bit | 1.6 μs |
DS2103 Multi-Channel D/A Board | 32 out | 14 bit | 10.0 μs |

1) Speed and timing specifications describe the capabilities of the hardware components and circuits of dSPACE products. Depending on the software complexity, the attainable overall performance can deviate significantly from the hardware specification.
2) Typical values at 25 °C and ±10 V output voltage range (FSR = full-scale range).
