Bridge Completion Selection
Jumpers W4–W7 and W10–W13 select half-bridge or full-bridge configuration for each channel
on the SC-2043-SG. Setting a jumper in the FB position disconnects the half-bridge completion
network from the channel and connects the CHn- screw terminal to the negative input of the
instrumentation amplifier for full-bridge signal inputs. Setting a jumper in the HB position
disconnects the CHn- screw terminal from the instrumentation amplifier and connects the half-
bridge completion network to the negative input of the instrumentation amplifier. Table 2-6
shows the jumper settings for the half-bridge completion jumpers and Table 2-7 lists their
corresponding channels.
