Product Description
The SER8CH-HLF-1in is an 8 channel, 24 bit realtime continuous data acquisition
system with a low power consumption of 10 milliamps. At only 1" wide x 3"
long, it is well suited to many restricted space applications such as borehole
monitoring.
The system is the ultimate in ease of use. Simply connect it to a RS232 port,
provide power, and it is ready to communicate at 9600 baud. No device drivers
or complicated software setup is required.
A full featured DVM acquisition and display program is included for GUI
multimeter displays when desired. The software provided is supported under
Windows 7/8/10 and Linux 64 bit operating systems.
Buffered full and half copies of the A/D reference voltage are available on
the analog input header for
ratiometric sensor
applications and excitation. Samples at 1/2 Hz ( 2 second period ) from each
channel with a full scale input voltage range of 0 to 5 volts.
The bundled "in the box" system comes with all the accessories you need to
start acquiring data immediately. These include software, PDF User Manual, 9
VDC power supply, 6' RS232 serial cable, and header cables for analog input and
power/RS232.
