5 Electrical connection
The following can be connected for measurement signal conditioning:
S
Carrier‐frequency amplifiers
S
DC amplifiers
designed for strain gauge measurement systems.
5.1 Connection in a six‐wire configuration
Plug‐in contact 1 = measurement signal (+)
Plug‐in contact 6 = excitation voltage (-)
Plug‐in contact 5 = sense lead (-)
Plug‐in contact 7 = excitation voltage (+)
Plug‐in contact 3 = sense lead (+)
Plug‐in contact 8 = measurement signal (-)

Fig. 5.1 Connector pin assignment
With this connector pin assignment, the output voltage at the measuring
amplifier is positive when the transducer is loaded (
see Fig. 4.1 ). The pin
assignment for the cables available as accessories can be found in Section 8
on page 15 .
5.2 Connection in a four‐wire configuration
When transducers in a six‐wire configuration are connected to amplifiers in a
four‐wire configuration, the sense leads of the transducer must be connected
to the corresponding excitation voltage leads: Marking (+) with (+) and marking
(-) with (-),
see Fig. 5.1 . This measure also reduces the cable resistance of the
