IOLITE® Rack (R8, R8R, R12) highlights

Dual EtherCAT Bus

IOLITE is equipped with two EtherCAT buses in parallel. The primary bus is used for full-speed buffered data acquisition to a PC computer hard drive. The secondary bus is mainly used for the real-time low-latency data feed to any 3rd party EtherCAT-based control system.

High-End Signal Conditioning

IOLITE data acquisition systems feature high-quality analog and digital amplifiers that offer excellent signal quality. The amplifiers use 24-bit ADCs with up to 20 kHz sampling rate, freely software selectable.

Multiple Chassis Option

IOLITE R12 aluminum chassis is compatible with 19'' rack cabinets. It can fit up to 12 I/O amplifier modules. IOLITE R8 and R8R are rugged aluminum-compatible chassis for field use and can fit up to 8 amplifier module cards.

Redundant Power Supply

IOLITE main frame chassis feature an integrated redundant power supply. This provides maximum system reliability for mission-critical applications.

Wide Operating Temperature Range

While IOLITE DAQ systems are labeled to run at -10°C ... 50°C, certain configurations can operate in the -40°C ... +85°C temperature range.

Great Price/Performance

IOLITE offers a great price/performance ratio and is suitable for testbed integration and various industrial applications.

Redundant EtherCAT Bus Systems

IOLITE data acquisition system is equipped with two fully independent EtherCAT bus systems that work in parallel. 

The Primary EtherCAT Bus

The primary bus is used for perfectly timed and synchronized data acquisition via DewesoftX data acquisition software. It connects via EtherCAT RJ45 cable to any PC running DewesoftX DAQ software and is able to stream any number of input and output channels at high-speed to the PC's hard drive. 

The Secondary EtherCAT Bus

The  secondary IOLITE EtherCAT bus can be used in two ways:

  1. Low latency front-end interface for any 3rd party EtherCAT compatible real-time controllers.

  2. Additional bus for redundant 3rd party data acquisition system in critical DAQ applications.

Merging data acquisition and real-time control

Historically, data acquisition and real-time control existed in different worlds, and there was no overlap. Controllers, including PLC systems, prioritized rapid response to events, and data recording was a secondary function. At the same time, data acquisition systems focused on recording speed, neglecting real-time control completely.

However, many applications require both functionalities. For example, test benches require precise signal conditioning and signal processing, along with real-time control. Integrating DAQ instruments and PLCs required redundant cabling, each dedicated to a specific signal.

The introduction of the Dewesoft EtherCat-based systems like OBSIDIAN, IOLITE, and SIRIUS RT changed the landscape by offering dual independent EtherCAT data buses. With this innovation, one bus could be used for high-speed, buffered data acquisition and the bus could send low-latency data to third-party controllers. 

With today’s Dewesoft instruments, only one data bus is needed between the PLC and the DAQ, drastically reducing cable complexity. This not only simplifies installation but also avoids unnecessary analog-to-digital hardware on the controller side. Dewesoft systems elegantly merge control and data acquisition, solving the integration of DAQ and real-time control once and for all.

This feature is available to any third-party controller software with EtherCAT master enabled. Dewesoft systems can easily command and control actuators, for example.

The days of requiring two independent systems are gone - Dewesoft does it all.

19-inch Rack Cabinet Mount Chassis

IOLITE R12 aluminum chassis is compatible and can be mounted in any standard 19-inch rack cabinet. This is perfect for test-bed installations and high-channel-count data acquisition applications.

The IOLITE R12 chassis height is 3U and can host up to 12 IOLITE I/O modules.

The chassis offers IP30 environmental protection and can operate at -10 to 50 °C temperature. Some configuration variations allow operating from -40°C to 85°C. Please contact our local representative for the wide temperature option.

Rugged Boxed Chassis

In addition to a 19-inch rack cabinet compatible chassis, the IOLITE DAQ system is also available in standalone closed aluminum chassis compatible with SIRIUS data acquisition instruments. IOLITE R8 offers IP40 environmental protection.

The IOLITE R8 chassis provides 8 slots for IOLITE input and output modules.

The IOLITE R8 chassis offers IP40 environmental protection and can operate at -10°C to 50 temperature. Some configuration variations allow operating from -40°C to 85°C. Please contact our local representative for the wide temperature option.

Rugged Fanless Boxed Chassis

IOLITE R8r chassis is even more ruggedized with passive cooling (fanless). It offers 8 slots for IOLITE rack DAQ modules. IOLITE R8r is designed for use in harsh, dusty environments. It can withstand high shock and vibration conditions.

The IOLITE R8r chassis is rated with IP50 environmental protection and can operate at -10°C to 50 temperature. Some configuration variations allow operating from -40°C to 85°C. Please contact our local representative for the wide temperature option.

Perfect Signal Conditioning

IOLITE offers high-end signal conditioning. With its range of input and output slots, you can measure voltage, current, strain, stress, vibration, sound, temperature, digital, counters, and more.

Proven high-quality data acquisition hardware combined with award-winning DewesoftX data acquisition software performs data collection without losing even a single sample. It also provides great data visualization and processing capabilities.

High-Channel-Count Applications

IOLITE data acquisition and control systems offer perfect and cost-efficient installation for high-channel-count applications. Systems can be daisy-chained together and can reach hundreds or even thousands of I/O channels. The channel count is only limited by the bandwidth limit. 

With Dewesoft NET configuration, systems can even be dislocated and distributed into several locations and act as one DAQ system controlled from the central control room.

With 19'' cabinet compatibility, IOLITE R12 systems can easily be installed in your existing cabinet infrastructure. 

Redundant Power Supply

IOLITE R8 and IOLITE R12 data acquisition systems are 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 the IOLITE DAQ system gives the operator the capability 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 easily show the pressure signal as well as the 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.

Real-Life Application Example - Durability Testing

Automotive durability test benches require hundreds of input channels for very precise data acquisition. They need to record force, torque, linear or angular motion, and more. Everything must be acquired with high precision and fast sample rates

Typically, the data acquisition devices are connected to PLCs which control the tests via analog outputs. Each analog output from signal conditioning is connected to the PLC inputs. Hundreds of signals … hundreds of cables … long set-up times and lots of work to connect everything.

With the IOLITE DAQ and control system, only a single EtherCAT digital interface is required to capture all of this data in real-time and then perform actions via its analog, digital, or CAN outputs.

As a final touch, DewesoftX DAQ software monitors the performance of the real-time controller, making sure that the controller and actuators are working flawlessly.

IOLITE is perfect for Industry 4.0 automation, automotive test benches, aerospace component testing, structural monitoring, and alarming - just to name a few applications.

The dual bus technology is already recognized and used in the testing of the most advanced systems in the world, including testing a new rocket propulsion engine for the most powerful European rocket ever built.
