Functional Diagram for the 50-297 High Density
Precision Resistor Card
The 50-297 provides a simple solution for applications
requiring accurate simulation of resistive sensors.
It is available in a variety of resistance ranges and
resolutions to meet the needs of most functional test
systems. It is particularly suited to engine controller
test applications where resistive sensors provide
information such as temperature.
The channels of the 50-297 are able to simulate the
common short circuit and open circuit conditions that
can be experienced in a system due faults in wiring or
sensors.
Software control of the 50-297 is simplified by the use
of resistor value calls. The card works out the channel
setting closest to what has been requested and sets
that value. The user can interrogate the card to find the
actual resistance setting used.
A calibration cable assembly can be attached to the
card to enable an external DMM to be connected to
each channel in turn for verification purposes. This
considerably simplifies the effort required to check the
card’s calibration. Verification is performed with the
UUT disconnected from the card.
The 50-297 is available in 50 standard builds that suit the
most common configurations required:
• A narrow resistance range version, available in 9 or 18
channel variants.
• A medium resistance range version, available in 4 or 9
channel variants.
• A wide resistance range version, available in 3 or 6
channel variants.
