GENERAL

The VersaVU Paperless Recorder is a
freely configurable microprocessor-based
device for measurement, storage, visual­ization, monitoring, and documentation.
Available with 4, 8, or 12 universal inputs
VersaVU is expandable to an additional 12
inputs via Modbus communications.

Measured data is buffered in internal flash
memory and can be exported to a USB
stick via the front USB port. Data can also
be viewed via a standard web-browser for
quick evaluation and analysis of historical
data trends.

VersaVU has been designed for industrial
use incorporating the latest means for
communications. Complete configuration
can be accomplished using the standard
Ethernet interface and on-board webserver
which also permits easy to access data
monitoring. E-mail messaging and FTP
functions add the finishing touches for
complete user convenience . . all as stan­dard features!

Measurement values can be displayed
either as trend curves in horizontal or verti­cal direction or bargraphs; a numeric dis­play is also possible.

IP 65/NEMA 4x Front Panel Protection

VersaVU allows up to 8 visualization groups
with up to 12 input channels per group.

Bargraph display

Different display views can be activated
within each visualization group.

A Modbus serial interface is also standard
allowing the unit to function in slave or
master operation.

All of our product features are brought
together on our 6.4" TFT color display. We
incorporated full VGA resolution (640 x 480
pixels) with wide viewing angles making
full use of the screen size. This type of
resolution makes it easy to use complex
display strategies without sacrifice to visi
bility.

Digital display

VersaVU features a group manager allowing
the user to assign input signals to visualiza
tion groups.

Input signals can be assigned to multiple
groups improving transparency. Different

-

parameters can be used for every input
within a specified group.

A historical display of the data stored in
memory can be viewed via the Horizontal

Accuracy and display

The errors specified in the table are
referred to the following conditions:
Humidity: 55% ± 10%
Temperature: 23 °C ± 2°C

Supply voltage: 100 to 240 V at 50/60 Hz ±
1%

VersaVU requires a 30 minute warm-up
period.

Standard performance

- Measuring accuracy (in %)

DC: +/- 0.1% of Span +/- 1 LSD
RTD: +/- 0.1% of Span +/- 0.3 deg C
TC: +/- 0.1% of Span, + 1 deg C
Cold Junction Compensation Error:
+0.3 deg C for 0.1 deg C resolution ranges
or 1 deg C for 1 degree resolution ranges

Recording accuracy (in resolution of the
digital display)

Fastest recording & displaying rates are 1
second. (1 data point per sec in file&1pix
per sec on display).
