The 40-295 is a programmable resistor module with up to 18
resistor chains with 8-bit resolution in a single PXI module. The
module to can also be supplied in 12, 16 or 24-bit resolution
versions for applications requiring ner resolution, greater
resistance range or higher channel count. The module is ideal
for simulating sensors for control and management systems, or
verifying system response in design verication or manufacturing
test.
The 40-296 version is wired as a potentiometer with two end
connections and a wiper.
The model is available with a variety of channel counts to allow
the user to choose the lowest cost solution for their application.
Versions with other resistance values can be provided to meet
specic requirements. This includes the tting of an offset
resistor to set the minimum resistance. If versions are required
with different resistance ranges, please contact the Pickering
Interfaces’ Sales Ofce for assistance.
All switches are instrument grade reed relays with low thermal offset
voltage to ensure operation under all conditions and a long service life.
The module is supplied with VISA drivers and a soft front panel.
