Embedded Data Acquisition System

The OBSIDIAN® Instruments are Dewesoft’s high end data loggers and embedded data acquisition systems centred around a low power ARM processor and Linux based open architecture operating system.

This makes it a truly flexible device with a range of potential uses.  Such as a stand-alone data logging system, real-time control system or a signal conditioning system with cloud or Industry 4.0 connectivity.

OBSIDIAN® offers great signal conditioning. With its range of multi-channel signal amplifier cards available for voltage, current, IEPE, thermocouple, RTD and strain gauge sensors.

Like all other Dewesoft Hardware, the industry leading DewesoftX Data Acquisition Software for the OBSIDIAN® is included for free (including maintenance and upgrades).

An Embedded data acquisition system for the future is the Dewesoft OBSIDIAN®.

Based on an open architecture, low power LINUX based ARM Processor.  The OBSIDIAN® is a data logger, stand alone data acquisition, real time system and signal conditioning frontend, all at the same time.

In addition, Dewesoft RT is a new embedded data acquisition software that runs on the Linux operating system platform.  It features lightweight core components for data acquisition, channel configuration, data storage and standard interface support.  For items such as XCP, CAN, USB, Ethernet and EtherCAT. It is capable of fast data transfer and real time operation in control or watchdog functionality.

Features of OBSIDIAN® Embedded Data Acquisition and Data Logger System include:

EMBEDDED PROCESSING: Built-in dual-core 1.5 GHz ARM processor with Linux OS and DewesoftRT.  Therefore, perfect for embedded applications.  Such as data logging, cloud data collection, real-time control and Linux DAQ.

DATA STORAGE: 32GB of Internal storage.  Expandable up to 1TB with SD Card or a USB Type C External HDD or SSD for large amounts of data.

LOW POWER CONSUMPTION: Extremely powerful.  Designed to operate with very low power consumption.  Therefore, making it the perfect choice where power consumption is important.

HIGH-END SIGNAL CONDITIONING: OBSIDIAN® Core Amplifiers offers the same high-end signal conditioning modules as IOLITE DAQ and control system. Amplifiers are available for Voltage, Current, Resistance, Strain gauge, Bridge, Digital Counters, RTDs, and Thermocouples.

WIDE TEMPERATURE RANGE: Labelled to run at -10 to 50°C.  However, certain configurations can operate in the -40° to 85°C temperature range.

EXTERNAL MASTER MODE: The primary EtherCAT® bus can be switch to external mode.  Allowing OBSIDIAN to be used like a regular IOLITE system for full speed buffered DAQ to a computer running DewesoftX Data Acquisition Software.

SECONDARY ETHERCAT BUS: A secondary EtherCAT® bus can be used in parallel to provide real time data to any 3rd party control system.  Such as Labview, Beckhoff, Clemessy Syclone, MTS Flex Test, Acontis and similar EtherCAT masters.

GREAT CONNECTIVITY: Standard data interfaces are available to transfer the data to real-time controllers, cloud servers, Industry 4.0 clients, using a wide variety of standard data interfaces, such as EtherCAT®, OPC UA, XCP, and CAN.

DAQ SOFTWARE INCLUDED WITH FREE LIFETIME UPGRADES: The easy-to-use but rich in functionality, award-winning Dewesoft X data acquisition software is included. All upgrades to the software are free forever with no hidden licensing costs.
