SIRIUS® R2 and R4 are compact data acquisition systems with a maximum of 64 analog inputs, 32 counter inputs, and 32 analog outputs. The DAQ systems feature a built-in high-performance, highly reliable data processing computer and SSD data logger which can optionally be replaced by a USB hub for a connection to an external PC.
 
SIRIUS® R2 and SIRIUS® R4
SIRIUS® R2 and R4 are compact medium to high-channel-count data acquisition systems. All channels are fitted inside a compact and rugged chassis design. Multiple SIRIUS® R2 and R4 data acquisition systems can furtherly be connected and synchronized together to extend the channel count, even to thousands of channels.
 
SIRIUS® R2
32 analog input channels
16 counter/encoder input channels
48 digital input channels
18 CAN bus input channels
16 analog output channels
 
SIRIUS® R4
64 analog input channels
32 counter/encoder input channels
92 digital input channels
36 CAN bus input channels
32 analog output channels
 
Powerful SBOX computer built-in
At the heart of the SIRIUS® R2 and R4 data acquisition systems is a powerful SBOXse computer. The computers are powered by an Intel® Core CPU, powerful enough even for the most demanding signal processing tasks:
 
SIRIUS® R2: Intel Core i7 CPU.
SIRIUS® R4: Intel Core i7 CPU.
 
SBOX computer is equipped with 8 GB of memory and is optionally upgradeable to 32 GB. A fast internal SSD drive provides reliable storage for long-term and high-speed data recording.
 
EtherCAT® expansion port
SBOX is also equipped with an EtherCAT® slave port which can be used to expand and distribute additional analog channels by connecting any of our EtherCAT®-based data acquisition modules such as KRYPTON or SIRIUSe.
 
SIRIUS® R2-HUB and SIRIUS® R4-HUB
If you prefer to connect the SIRIUS® R2/R4 to an external PC then we offer SIRIUS® R2-HUB and R4-HUB data acquisition systems. They feature an integrated USB hub instead of an SBOX computer and stream data directly to an external PC via the USB 2.0 connection.
 
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.
 
DualCoreADC technology prevents these problems. Each channel amplifier has two A/D converters that measure the high and the low gain of the input signal in parallel. This results in the full possible measuring range of the sensor and prevents the signal from being clipped. 
 
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.
 
SuperCounters®: precise speed and angle measurement with counter and encoder sensors
Dewesoft data acquisition systems utilize a patented and registered trademark technology called SuperCounter®.
 
Analog outputs
SIRIUS® R2 and R4 data acquisition systems can optionally be configured with analog output channels:
 
SIRIUS R2 up to 16 analog outputs
SIRIUS R4 up to 32 analog outputs
 
Analog output channels can function in any of the following modes:
 
Standalone digital signal amplifier
Multi-channel function generator for modal/shaker control - software upgrade option required
Control channels
A replay of the analog data
 
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
SIRIUS® R8
 
Integrated GNSS positioning with RTK correction
SBOX computers can optionally be equipped with a 10 Hz or 100 Hz GNSS receiver for precise position measurement applications. GNSS receivers can optionally also be configured to support RTK correction (Real-Time Kinematics).
 
SBOX with GNSS receiver will transform the data acquisition system into a powerful automotive data logger for advanced position-based test and measurement applications such as:
 
Brake testing
ADAS testing
Pass-by-noise
Vehicle dynamics
Road load data
and others.
