Main Features

  • DUAL ETHERCAT: IOLITE uses two EtherCAT buses in parallel. EtherCAT primary bus is used for full speed buffered data acquisition to a computer. EtherCAT secondary bus is mainly used for real-time data to any 3rd party control system.
  • GREAT SIGNAL CONDITIONING: IOLITE features high-quality amplifiers which offer great signal quality and up to 20 kHz sampling rate. 
  • REDUNDANT POWER SUPPLY: Together with dual EtherCAT interface provides maximum system reliability. 
  • MULTIPLE CHASSIS OPTION: IOLITE can be configured in the 19-inch cabinet compatible chassis or in more rugged SIRIUS-like compatible chassis. 
  • GREAT PRICE/PERFORMANCE: IOLITE offers great price/performance ratio and is suitable for test-bed and industrial applications.
  • SOFTWARE INCLUDED WITH FREE LIFETIME UPGRADES: Easy to use, yet very robust in functionality, award-winning DEWESoft X3 software is included. The software comes with lifetime free upgrades and no hidden costs, bringing you intuitive configuration, smart sensors, advanced storage and analysis capabilities.

Redundant Bus Systems

Each IOLITE system has two fully independent Ethercat bus systems that work in parallel. 

Primary Bus

Primary bus is used for perfectly timed and synchronized data acquisition via DEWESoft X software.

Secondary Bus

The secondary bus can be used in two ways:

  • low latency front-end interface for real-time controllers
  • redundant data acquisition bus system for critical applications

Input Slots and Amplifiers

IOLITE chassis can be configured with up to 12 slots, each featuring high-quality input amplifiers. Currently, the following amplifiers are available:

  • 6xSTG: universal analog and strain gage amplifiers. Compatible with Dewesoft smart interface DSI adapters
  • 8xTH: isolated thermocouple amplifier
  • 8xRTD: isolated universal PTx temperature, resistance, and voltage
  • 32xDI: 32 channel digital input
  • 32xDO: 32 channel digital output with watchdog

See tech specs page for full technical specifications.


Six channel universal differential analog with 20 kS/sec per channel sampling rate. This module can acquire:

  • Analog voltage up to 50 V
  • Full, half and quarter bridge strain gage channels
  • Potentiometer
  • IEPE channels (using DSI adapters)

It also features channel independent programmable power supply to power sensors.


Isolated thermocouple module can acquire data from any kind of thermocouple (K, J, T, R, S, N, E, C, U, B).

It offers sensor break detection in software as well as using LED indicator.


8 isolated universal PTx temperature, resistance, and voltage input channels for PT-types

  • PT100,
  • PT200,
  • PT500,
  • PT1000,
  • PT2000

It offers sensor break detection in software as well as using LED indicator.


Digital input module with screw terminal and power supply is perfect for high channel count  data acquisition and control applications.


Digital output module with screw terminal and power supply is great for control application with feedback monitoring. The module also includes watchdog function.

Redundant Power Supply

Each IOLITE system is equipped with a redundant power supply completing the feature set for the ideal and reliable front-end system. 

If the primary power supply fails, the system will be powered by a secondary power supply without any interruption or system shutdown/restart.

Feedback Monitoring

What is really amazing is that IOLITE offers the operator to acquire and monitor the data in daily operation as well as while tuning the control systems.

Apart from monitoring the input channels on the data acquisition bus, the system can also monitor the outputs from the controller. Let's say we regulate the switch-off valve by monitoring the pressure. DEWESoft can show the pressure signal as well as digital output signal coming from the controller, all fully synchronized.

This allows the operator to prove that the control system is operating correctly every time.

Cabinet Mount Chassis

Standard IOLITE chassis is compatible and can be mounted in any 19-inch rack cabinet. This is perfect for the test-bed installations.

IOLITE height is 4U and can host up to 12 IOLITE modules.


Boxed Chassis

In addition to 19-inch rack cabinet compatible chassis, IOLITE is also available in standalone aluminium chassis compatible with SIRIUS data acquisition instruments. 

The chassis provides 8 slots for IOLITE input and output slices to be installed.

Data acquisition software

All Dewesoft data acquisition systems are bundled with award-winning Dewesoft X Professional - world's most advanced and easy-to-use data acquisition and analysis software. With the power of DEWESoft X, you can unleash the DAQ system to its full potentials. It gives you many advantages over other DAQ systems. Functionalities like plug-and-play, hardware auto detection, smart sensors, advanced storing and data analysis features will elevate your measurement and analysis skills to a whole new level.

Plug and Play

Connecting the DAQ system and sensors could not be faster or easier. DEWESoft X will automatically detect the connected DAQ systems and TEDS equipped sensors and will configure the entire channel configuration for you. Features like:

  • hardware auto-detection,
  • smart sensors,
  • sensor database,
  • advanced TEDS support,
  • automatic unit conversion,
  • real-time signal preview,
  • store setup files

will make you ready for measurement in seconds. Spend less time configuring your DAQ systems and be more productive. Time is money!

Measure and Store

Powerful storing capabilities with more than 500 MB/s sustained stream rates means you can always store data at full speed and never again worry about losing data that could compromise your tests. DEWESoft X features:

  • real-time data acquisition,
  • synchronized acquisition of analogue, counter, video, GPS, CAN bus, and many other sources,
  • advanced triggering and alarms,
  • single or multi-file storage,
  • remote and distributed network storing,
  • automated test sequences.

Even if you store gigabytes of data, our innovative data file format will ensure you can load and analyze your data as fast as a blink of an eye.
