2.14 Connecting Bridgeheads
You can measure strain by connecting a strain gauge bridge (bridge head) or a strain gauge
transducer to the strain module (701270 (STRAIN_NDIS) or 701271 (STRAIN_DSUB)).
This section will mainly describe the procedures and precautions related to the connection of the
bridge head (Model 701955, 701956, 701957, and 701958). For the connection of other strain gauge
bridges or strain gauge transducers, see the respective manuals.
CAUTION
Only connect a strain gauge bridge (bridge head) or a strain gauge transducer to the strain
module. Connecting other devices or applying a voltage that exceeds the values indicated
below to the strain module may damage the input section.
• Maximum input voltage (between Input+ and Input–)
10 V (DC + ACpeak)
• Maximum rated voltage to ground (between each terminal and earth ground)
42 V (DC + ACpeak) (CAT II, 30 Vrms)

ATTENTION
Brancher seulement un pont de jauge de contrainte (tête de pont) ou un transducteur de jauge
de contrainte au module de contrainte. Le fait de brancher d’autres appareils ou d’appliquer
une tension dépassant les valeurs indiquées ci-dessous sur le module de contrainte risque
d’endommager la zone d’entrée.
• Tension d’entrée maximale (entre l’entrée + et l’entrée –)
10 V (c.c. + crête c.a.)
• Tension nominale à la terre maximum (entre chaque borne et la terre)
42 V (c.c. + crête c.a.) (CAT II, 30 Vrms)
Connecting the Strain Gauge
The bridge head (701955, 701956, 701957, and 701958) supports six types of connection methods:
single-gauge method, single-gauge three-wire method, adjacent-side two-gauge method, opposite-
side two-gauge method, opposite-side two-gauge three-wire method, and four-gauge method. For
details, see the manual that came with the bridge head (701955, 701956, 701957, or 701958).
If you are using a strain gauge bridge or a strain gauge transducer other than the bridge head
(701955, 701956, 701957, and 701958), see the respective manuals.
