RA2800A Data Acquisition System


The RA2800A, formerly known as the SOLTEC TA220-2800, from A&D is a 32-channel capable version of the RA2300A data acquisition system. 16 physical slots capable of monitoring up 32 channels enable use of any of 12 A&D plug-in amplifiers to interface to a range transducers and event triggers.


  • Multi-channel Measurement

Direct sensor inputs up to 32 channels (16 slots). 16 digital inputs for measuring various timing signals.

  • Unique and easy "Pen-Recorder" Mode

Easy operation like a pen recorder by the touch panel and virtual amp controls. High-speed and high-quality printout at max 50mm/sec.

  • Large 12.1" Display

12.1" TFT color LCD display for better visibility of measured data.

  • Long-term continuous recording on HDD Built-in 40GB HDD provides 60 days recording

At 10ms sampling on 32 channels

  • User selectable measurement modes

With Omniace III RA2800A, users can easily select from five (5) measurement modes: Pen Recorder mode for real time strip chart recording, HD Recorder mode for long term recording of data to an HDD, X-Y Recorder mode for displaying/recording X-Y correlation of two signals, Multi Recorder mode captures transients while recording steady-state signals, and a Memory Recorder mode for recording fast events.

Measuring Modes

  • Simple Operation

A "virtual" Amplifier Control Panel with "Auto Function" automatic adjustment mode combined with our proven reliable touch panel guarantee accurate data recording and simple operation.

  • Upright Type (easy setup on a bench top or rack)

Parts configuration for measurement on a bench top or rackcontrol, display and printer units on the front; amplifiers and interfaces on the back.

  • High-speed & High-quality Printing

Real time selectable chart speeds from 50mm/sec to 1mm/min (resolution: 20 dots/mm).

  • 32 channels analog and 16 channels digital recording

Input up to 32 channels of analog data via isolated, dual channel, plug-in amplifier modules for a wide variety of signals and sensors.Its 16 digital input channels measure diverse signal timing and contact status.

  • Outstanding Search Function

Max/Min, time and other search functions are available for finding required data points automatically after long term measurement.

  • Standard LAN and USB I/F

LAN (100BASE-T) for data communication and USB for connecting to external storage devices are equipped as standard interfaces.

Model Continuity

The Soltec data recorder product line was acquired by A&D in 2015, and since that time, we have continuously supplied products to governments and commercial firms. The list of data recorders includes the following models:

Omniace Falcon II TA220-2300
Omniace Falcon II TA220-2300A
Soltec Falcon II TA220-2300A
Omniace Falcon II TA220-2800
Omniace Falcon II TA220-2800A
