Product Exclusive: Dataforth 8B isoLynx SLX300 DAQ system

A new data acquisition system from Dataforth, with application software and isolated signal conditioning modules are said to offer superior reliability and isolation. Dataforth ReDAQ Shape DAQ software allows users to easily create, save, and open graphical user interface projects, as well as to test, process, and analyze acquired data, the company says. This is an October 2010 Control Engineering Product Exclusive.


Dataforth 8B isoLynx SLX300, a new data acquisition system, builds on the proven reliability and performance of the Dataforth SCM5B isoLynx SLX200 and miniature SensorLex 8B isolated signal conditioning modules to provide a compact, low cost solution for wide ranging rugged industrial applications.

Dataforth ReDAQ Shape, out-of-the-box DAQ software for the SLX300, provides the easiest and most efficient development tool to create, save, and open graphical user interface projects as well as to test, process, and analyze acquired data. The software provides the most effective way to set up and configure SLX300 functions.

The data acquisition system features:

  • Modbus RTU and TCP support;
  • 1500 V rms input-to-output and channel-to-channel Isolation;
  • 240 V rms field-side protection;
  • Wide I/O selection;
  • Mix and match analog and digital I/O;
  • Advanced features including alarms, counters, timers and PWMs; and
  • CE and RoHS compliant, C-UL-US (Class 1, Div 2, Groups A,B,C,D) pending.

Modular design provides the system with flexibility: users can choose from 70 analog and 14 digital I/O modules and configure the system with up to 12 channels of isolated analog input, 4 channels of isolated analog output, and 8 channels of isolated digital I/O.

Ensuring broad functionality, the 8 digital I/O channels can be configured to perform seven advanced special functions: pulse/frequency counter, pulse/frequency counter with de-bounce, waveform measurement, time between events, frequency generator, PWM generator, and one-shot pulse generator. The SLX300 also enables four alarm states – high, high-high, low, and low-low – to be set on the analog input and digital I/O special function channels.

High-speed microcontrollers and high performance data converters enable simultaneous analog and digital I/O at sustained rates of up to 3.0 kS/s, as well as high-speed acquisition to 100 kS/s burst on analog input channels. Use of industry standard Modbus RTU or TCP protocols allows communication with third-party software tools and HMI/SCADA packages. Other SLX300 system features include panel or DIN rail mounting and rack-mounted or bench top 1U enclosure. A free configuration tool ensures easy system setup.
