DNF-4-1G – I/O FlatRACK DAQ Platform

FLATRACK™ Ethernet I/O DAQ Platform

The DNF-4-1G is a compact, rugged and highly integrated Ethernet I/ O data acquisition platform. The platform is ideal for applications in which point-to-point signal conditioning and patch panel connections can be avoided.

  • Complete DAQ interface to any input/output/sensor type
  • Standard rack-mountable 1U chassis: 6.0″ x 1.75″ x 17.5″
  • Accommodates up to four I/O front-loading I/O boards
  • Compatible with >50 interchangeable I/O boards
  • Two independent Gigabit (1000/100/10Base-T) Ethernet Interfaces
  • Inter-RACK and multiple RACK sync Interface
  • AC & DC powered versions available
  • Rugged: 3 g Vibration, 50 g Shock, -40 to +70°C
  • Real-time: 1,000 I/O scans in <1 millisecond
  • Complete Windows, Linux and RTOS support
  • LabVIEW,™ MATLAB®, and Simulink support and more

A variety of Ethernet-based communications modes have been optimized for common application types to provide a reliable interface between the host PC and the FLATRACK. These include:
  • Single-Point Programmed I/O
  • ACB: Advanced Circular Buffer
  • DMAP: Digital Media Access Protocol

No system is complete without software. The DNF-4-1G FLATRACK is supported by all popular Windows, Linux, Vista, and real-time operating systems (RTOS). The UEIDAQ Framework (included with the rack) provides a simple and universal API layer to support all common programming languages.
There are AC and DC powered versions of the DNF-4-1G. The DC version requires a DC power source between 9 and 36 Volts. The AC unit operates from 100 to 240 VAC, from 50 to 60 Hz.
