Refer to the EXP-16 and EXP-16/A expansion board documentation for
more information about these expansion boards.
Attaching an EXP-GP Expansion Board
Each EXP-GP expansion board provides up to eight analog input
channels (labeled 0 to 7). The EXP-GP provides six screw terminals for
each channel: positive current excitation (+IEXC), positive input
(+SENSE), negative voltage excitation (
−
P), negative current excitation
(
−
IEXC), negative input (
−
SENSE), and positive voltage excitation (+P).
To connect an EXP-GP to a DAS-800 Series board, attach one end of the
S-1800 or C-1800 cable to the main I/O connector on the DAS-800 Series
board and the other end of the cable to the J1 connector on the EXP-GP.
Figure 4-6 illustrates the connection of an EXP-GP to a DAS-800
Series board.
