Expansion modules Stationary KiDAU Advanced / K3880AS

The Stationary KiDAU Advanced has eight analog inputs. The application of different connectors, as well as pin assignments for the 8 analog inputs, will be mapped using different SD panels. Each analog channel comprises a programmable input amplifier, bridge excitation circuit, low pass filter, and a 16-bit A/D converter. The amplifier precision is better than 0.1% and the input impedance is above 10 MΩ. The gain values can be programmed from 0.5 to 10000. An internal reference voltage is used for precise control of the amplifier setting, which is achieved via software. The bridge excitation voltage is programmable separately for each channel. Bridge completion for half bridges can be switched internally. All current sensors may be supplied, a short circuit limitation is provided. In contrast to former designs, the input low-pass filter is designed only as an adaptive antialiasing filter. All necessary filtering according to SAE filter classes has to be done in the evaluation and analysis software or the CrashDesigner. Each channel of the Stationary KiDAU Advanced has its A/D converter with a 16-bit resolution. All channels are sampled simultaneously, ensuring that no time lack occurs between different channels. The maximum sampling rate is 100 kHz. Each channel has a dedicated D/A converter of its own for compensation of the offset voltage. All adjustments are implemented by software, automatically, or by command.
