SIRIUS® R8 is a high-channel-count data acquisition system with up to 128 analog input channels. It is equipped with high-end signal conditioning amplifiers for almost every sensor and signal. The system features a built-in powerful processing computer with reliable SSD storage and a myriad of modern connection interfaces.
 
SIRIUS® R8 high-channel-count data acquisition system
SIRIUS® R8 is a high-channel-count analog data acquisition system for the most demanding test and measurement applications. It features high-end signal conditioning amplifiers with the latest ADC technologies.
 
SIRIUS® R8 systems can be configured with up to:
128 analog input channels
192 digital input channels
64 counter/encoder channels
72 CAN bus input channels
64 analog output channels
 
All channels can be configured in one compact and rugged main frame chassis. SIRIUS® R8 is one of the most compact data acquisition systems on the market with a high number of input channels. 
 
SIRIUS® R8R for extreme ruggedness
SIRIUS® R8 data acquisition system is built inside an extremely rugged aluminum chassis. It is tested to work in all sorts of testing scenarios. 
 
Powerful SBOX computer built-in
SIRIUS® R8 and R8R data acquisition systems are equipped with a powerful SBOXre computer. The computers are powered by the 11th gen. Intel® Core i5 CPU. The CPU is powerful enough even for the most demanding signal-processing tasks.
 
SBOX computer is equipped with 32 GB of memory and is optionally upgradeable to 48 GB. A fast internal SSD drive and removable SSD drive provide reliable storage for long-term and high-speed data recording.
 
SIRIUS® signal conditioning technology
Data acquisition systems are built around our world-class SIRIUS® signal conditioning technology and offer the same top-performing technologies:
 
DualCoreADC® technology: high-dynamic range and signal-to-noise ratio (SNR).
SuperCounter® technology: high-speed synchronized angle and speed measurement.
Galvanic isolation: channel-to-channel and channel-to-ground isolation for best signal quality and safety.
 
Note: galvanic isolation does not apply to SIRIUS mini and MINITAURs instruments.
 
Available signal amplifiers
SIRIUS® data acquisition systems offer different signal conditioning amplifiers grouped into three main amplifier families.
 
DualCoreADC® amplifiers
High-density (HD) amplifiers
High-speed (HS) amplifiers
 
DualCoreADC® signal conditioning technology
 
The DualCoreADC® technology solves often-faced problems with signal measurement:
signal input overload,
noise, and
artificial frequencies in the signal caused by aliasing.
 
The input signal can be higher than expected by the signal conditioner (out-of-range) and therefore clipped by the ADC. This will result in an incorrect measurement and will require you to repeat the test all over again.
 
Channel-to-channel galvanic isolation
SIRIUS DAQ devices offer high galvanic channel-to-channel and channel-to-ground isolation (±1000 V). The DAQ systems even offer isolated sensor excitation.
 
With such isolation, we have no problem measuring high voltage potentials and no problem with common-mode voltages. We are also safe with measurements like vibrations, temperatures, or any other measurement where non-isolated sensors are placed next to the high voltage potential against the DAQ system ground. In such cases, a non-isolated DAQ system would burn or at least give faulty wrong results. With SIRIUS it is just one thing less to worry about.
 
SuperCounters®: precise speed and angle measurement with counter and encoder sensors
Dewesoft data acquisition systems utilize a patented and registered trademark technology called SuperCounter®.
 
Counter inputs can measure the RPM and angle of rotating machines. In comparison to standard counters, which only output integer numbers one sample later (e.g. 1, 1, 2, 2, 3, 4), the Dewesoft SuperCounter inputs are able to extract accurate values like 1.37, 1.87, 2.37, etc. fully synchronized for time and amplitude.
 
External calibration reference
SIRIUS® R8 systems feature optional calibration reference input. External calibration reference can be connected via a single BNC connector on the rear side of the system. It can be switched in the software to all input channels at once to check the amplifier performance and accuracy.
 
Analog Out
SIRIUS® R8 system can be configured with up to 64 analog output channels. These output channels can function in any of the following modes:
 
stand-alone digital signal amplifier,
multi-channel function generator for modal/shaker control,
control channels or
a replay of the analog data.
 
Analog Output Modes
The analog outputs on SIRIUS can be configured and used with one of the following modes of operation.
 
Function Generator
Standalone Signal Conditioning
Control Channels
File Replay to Analog
 
Real-time, low-latency data output
We offer an "RT" (real-time) version of SIRIUS® data acquisition systems. These systems include a secondary EtherCAT® data bus on the back side of the instrument. This data bus can be used to output reduced rate data in parallel in real-time to any 3rd party EtherCAT® masters.
 
The real-time EtherCAT® bus is available on the following SIRIUS systems:
 
SIRIUS® modular EtherCAT®
SIRIUS® R2, R2-HUB
SIRIUS® R4, R4-HUB
