Hi,
SC-2050 is just a cable adapter board for routing the DAQ device lines to various signal conditioning accessories. So whether you can measure strain gauge measurements or not depends on the signal conditioning accessory you have. For example if you have SC-2043-SG, you should be able to make strain gauge measurements.
You can take a look at the following links.
SC-2050 SC-2043-SG Please do let me know if you have any questions.
Sincerely,
Sastry V.
