5. Electrical Connection Information
This section contains detailed information about the electrical connections of the various F/T system
components.
Aside:
Information in this section is intended for advanced users. Users whose systems
include an ATI-supplied DAQ card may skip this section.
The ATI DAQ F/T software features a modular design to allow you to use our system with any data
acquisition system capable of electrically interfacing to the transducer.
Once you have obtained the digitized transducer data per your data acquisition card instructions, the
data needs to be transformed into force and torque data using the drivers and instructions on the ATI
DAQ F/T software CD.
5.1 Signals and Power
Signal Name Description
SGx Output The non-inverting (positive) half of output of SGx
SGx Reference The inverting (negative) half of output of SGx
+V
ANA
Positive power supply used by transducer
AGnd Power supply return used by transducer
-V
ANA
Negative power supply used by transducer
+5V Positive power used by PS or IFPS box
0V Power supply return used by PS or IFPS box
AIGnd Analog Input Ground used for input current return from data acquisition card
Reserved This connection has an internal or future use. Do not use.
Table 5.1—Signal Descriptions
Systems with an ATI supplied DAQ card have their power derived from the DAQ card. If
you are using your own DAQ card, you will need to provide a +5V power and 0V power to
the PS or IFPS box. Without a PS box you will need to supply +V
ANA
, AGnd , and -V
ANA
power to the transducer. (This applies to 9105-TIF transducers only; 9105-TW transducers
require their IFPS box.)
CAUTION: The analog signals output by the transducer do not map directly into
force and torque vectors. ATI DAQ F/T software must be used to convert these
values into force and torque data.
