4.18.1 Full and half-bridge transducers
With (resistive) full bridges (strain-gauge full bridges) six connec-
tions are used per measuring point. If the sensor has
no sensing
leads, you specify this during the module configuration (Type col-
umn); the U
Sen
inputs then remain open. With half bridges the
side drawn in dashes and the U
Sig-
connection are omitted.
The bridge excitation voltage is 2 V
DC
; with 350  sensor resis-
tance you can also use 4 V
DC
. The internal shunt resistance can
be activated also with full and half bridges.
