IOLITE LX - Embedded Data Acquisition System

Embedded DAQ With Low-power ARM Processor and Linux OS

For the first time in history, the Dewesoft device is hosting an embedded low-power ARM processor. And what a processor it is...

Borrowed from cutting edge technology of mobile devices, the integrated ARM CPU can do powerful things, and all this with very low power consumption.

The ARM processor is running brand new Dewesoft RT data acquisition software on Linux OS. The combination of Linux OS, ARM CPU technology, and Dewesoft RT gives IOLITE LX completely flexible usage from stand-alone data logging applications, real-time control system, or just a signal conditioning system with cloud or Industry 4.0 connectivity. Possibilities are limited, and we have just begun!

IOLITE LX will get constant free software and firmware updates enabling new features. As always we will be listening to customer needs and we will steer our R&D roadmap to integrate these needs into the IOLITE LX system. IOLITE LX is more than just a standard data acquisition system. It is a platform that will evolve and grow!

Integrated Data Storage For Stand-alone Data Logging Applications

IOLITE LX has an internal data storage with up to 1 TB of memory. In addition to that, we have included a storage expansion slot for standard SD cards. This allows for easy storage expansion and also an easy way of transferring the data.

It is able to store any number of channels with a maximum sampling rate speed making it perfect for embedded data acquisition.

The acquired data is available in parallel to monitoring systems, such as the Dewesoft Historian time-series database, SCADA systems, or cloud data services.

Stored files can be reviewed and analyzed by anyone using included powerful and award-winning Dewesoft X data acquisition and analysis software.

Great Connectivity With Standard Data Interfaces

The acquired data is available to other data systems or controllers using standard data protocols included with IOLITE LX:

• EtherCAT is an industry-standard for real-time control applications. IOLITE LX uses two EtherCAT buses in parallel. The Primary EtherCAT bus is used for full speed buffered data acquisition to a PC computer while the secondary bus is mainly used to serve data in real-time to any 3rd party control system.
• OPC UA is a leading standard for Industry 4.0 applications. The data can be served to SCADA, ERPs, and MES systems as well as mobile clients in real-time.
• Dewesoft Historian cloud services and timed-series databases using OPC UA as a backbone provide historical data to all clients using a powerful and fast Influx DB database.
• CAN and XCP on Ethernet provide the data to ECU calibration software such as ETAS INCA or Vector CANape in real-time with minimum latency.

IOLITE LX Analog and Digital Input and Output DAQ Modules

IOLITE LX chassis can be configured with 8 IOLITE DAQ I/O modules each featuring high-quality input and output amplifiers. Currently, the following amplifiers are available:

• 6xSTG: Universal analog and strain gage amplifiers. Compatible with Dewesoft smart interface DSI adapters for expansion to Thermocouple, RTD, LVDT, current, and IEPE measurements.
• 8xLV: Isolated 8-channel low voltage module. This module is a perfect choice for a general-purpose voltage input data acquisition module due to high accuracy and high channel-to-channel and channel-to-ground isolation.
• 8xTH: Isolated universal thermocouple amplifier. Supports any thermocouple type sensors.
• 8xRTD: Isolated universal PTx temperature, resistance, and voltage.
• 32xDI: 32 channel digital input module.
• 32xDO: 32 channel digital output module with the watchdog functionality.
• 8xDI 4xDO: 8 digital input and 4 digital output channels.
• 4xCNT: 4 channel digital counter input with SuperCounter® technology.

All IOLITE DAQ modules are equipped with two independent EtherCAT buses in parallel for both DAQ and real-time control.
