PDQ30

Analog Input Expansion Module for
Personal Daq/3000 Series & DaqBoard/3000 Series
Features• Adds 24 differential/48 single ended
inputs to DaqBoard/3000 Series PCI
boards and PersonalDaq/3000 Series
USB modules• Any input can be a voltage or thermocouple• Convenient removable screw-terminal
connections
The PDQ30 increases total channel
capacity of a DaqBoard/3000 Series or
Personal Daq/3000 Series to a total of
32 differential or 64 single-ended analog inputs. The PDQ30 attaches to a
DaqBoard via an optional CA-266-x cable,
and to the Personal Daq/3000 either byplugging directly into the Personal Daq
with included clips, or via an optional
CA-96A cable if it is necessary to have somedistance between each device.
Voltage measurements via the PDQ30 havethe same ranges as the host PCI DaqBoard orUSB Personal Daq. When used with either
host, the PDQ30 also adds thermocouple
measurement capability, where the A/D
operates in a programmable, over-sample/
digital filtering mode to provide low-noiseand stable temperature measurements.
