A-3-1-3 T4 Signal Range [T-Series Datasheet]

T4 AIN Signal Range

Analog inputs on the T4 are single-ended only.  That means the voltage of a given input terminal is acquired versus GND, and thus the signal range is simply the same as the analog input ranges of ±10V or 0-2.5V discussed in various places.  See Appendix A-3 for further analog input specs.
