The
unique modular system design provides
plug-and-play functionality for
adding or
replacing sensors. The T9M260278 Data
Acquisition Module
includes the following
features larger nonvolatile memory, selectable
averaging intervals, 12 bit analog conversion,
0.1% F.S. accuracy, two
alarm outputs, and
ptional modem communications. o
The T9M260278 is
supplied with an attractive
desktop data acquisition module with a memory
capacity of 128KB RAM (approximately
45 days at 15 minute intervals with 6
sensors). The standard system includes a 120Vac
power adapter and RS232
serial port for connection to a personal computer. For outdoor
or remote
applications, two enclosure options are available. One is for sites with AC
power and the other utilizes a solar panel. Both options include a NEMA-4X
enclosure
and rechargeable battery to allow continued operation in the event
of power failure.
Data can be viewed using Windows HyperTerminal or
other terminal programs such as
Procomm. A one page real-time text display
or an ASCII row and column format may be
selected. A menu is provided for
setting the date and time, alarms, logging interval etc.
Optional graphical
displays software is available for viewing real-time and historical data
charts and graphs.
