The DS2002 and DS2003 Multi-Channel A/D Boards provide various resolutions, channel numbers and speeds for A/D conversion. The boards can be used to convert the analog voltages or currents from sensors (pressure, temperature, etc.), or from electronic control units (ECUs).
A/D conversion is an element of most applications in rapid control prototyping and hardware-in-the-loop (HIL) simulation. In rapid control prototyping, sensors for pressure, temperature, or other signals provide analog voltages or currents. In HIL simulations, the electronic control unit provides analog voltages or currents that control the simulated actuators.
The A/D boards provide various channel numbers, resolutions, and speeds for you to choose from. The table below gives you an initial overview. The boards can be configured from Simulink® by using Real-Time Interface. You can select the voltage range and the resolution separately for each channel or A/D converter.
Board | Channels | Resolution | Sample Time1) (2 Channels) | Sample Time1) (All Channels) |
---|---|---|---|---|
DS2002 Multi-Channel A/D Board | 32 in | 4, 8, 12, 16 bit, shortcycling | 3.9 μs (16 bit) | 66.9 μs (16 bit) |
DS2003 Multi-Channel A/D Board | 32 in | 4, 8, 10, 12, 13, 14, 15, 16 bit, shortcycling | 5.6 μs (16 bit) | 56.6 μs (16 bit) |
