3.4. Differential Analog Inputs (TB304)
To interface to a single-ended (non-differential) voltage source, connect the signal common of the source to
the negative input and the analog source signal to the positive input. A floating signal source should be
referenced to the analog common as shown in
.

N O T E :
Analog Input 0 on the I/O board is tied to Analog Input 0 on J205 (see
). TB304 lets
you connect to all of the analog inputs in one place (do not connect to AIN0 at both TB304 and J205).
