Table 1 shows the signals available if you plug the SCC-FT01 into
AI single-stage SCC sockets J1–J8 or AO SCC sockets J17 and J18.
When you plug the SCC-FT01 into a single-stage AI SCC socket, the
following conditions are true for the labeled screw terminals:
• CH+ connects to the lower AI channel number CH( X ), where
X is 0 to 7.
• CH– connects to the higher AI channel number CH( X +8), where
X is 0 to 7.
• AI GND connects to AI ground.
• AI SENSE connects to AI SENSE.
• EXT REF does not connect—do not use it.
Note
For information on AI modes, refer to the SC-2345 User Manual . For information
on AI configuration modes, refer to the DAQ device documentation.
When you plug the SCC-FT01 into an AO SCC socket, the following
conditions are true for the labeled screw terminals:
• CH+ connects to AO 0 for AO SCC socket J17, AO1 for
AO SCC socket J18.
• CH– connects to AO ground.
• AI GND connects to PFI 5.
• AI SENSE connects to AO 1 for AO SCC socket J17, AO 0 for
AO SCC socket J18.
• EXT REF connects to EXT REF.
