The OMB-PDQ30 analog input
expansion module increases
total channel capacity of an
OMB-DAQBOARD-3000
Series PCI bus data acquisition
board or OMB-DAQ-3000 Series
Personal Daq USB data acquisition
module to a total of 32 differential
or 64 single-ended analog inputs.
The OMB-PDQ30 attaches to
an OMB-DAQBOARD-3000
Series board via an optional
OMB-CA-266-3 cable, and to the
OMB-DAQ-3000 Series either by
plugging directly into the Personal
Daq module with included clips,
or via an optional OMB-CA-96
cable if it is necessary to have
some distance between devices.
Voltage measurements via the
OMB-PDQ30 have the same ranges
as the host OMB-DAQBOARD-3000
Series PCI board or OMB-DAQ3000 Series Personal Daq USB
module.
When used with either host,
the OMB-PDQ30 also adds
thermocouple measurement
capability, in which the A/D
operates in a programmable,
over-sample/digital filtering mode
to provide low-noise and stable
temperature measurements.
