If remote sensing is required, connect the RS+ terminal to one end of the strain
gauge (R
B1
) by an independent wire, and connect the RS- terminal to the other end
(R
B2
) by another independent wire, as shown in Figure 2.7 Do not share the same
wire for RS and EX terminals.

2.3.3 Full-Bridge Input Signal Connection
For full-bridge input, all four bridge arms are external sensing elements, hence the
name. This configuration is also called full-bridge completion.
Figure 2.8 shows full-bridge input without remote sensing signal connection. Connect
middle node of the two left arms (junction of R
B1
and R
B2
) to both AI+ and QTR/SC+
terminals using different wires, and middle node of the two right arms (junction of R
B4
and R
B3
) to AI- terminal. Connect the middle node of the two upper arms (junction of
R
B1
and R
B4
) to EX+ terminal, and the middle node of the two lower arms (junction of
R
B2
and R
B3
) to both EX- and SC- terminals using different wires. Since remote
sensing is not used in this configuration, simply connect RS+ and RS- terminals to
EX+ and EX- terminals, respectively.
