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 7
on page 16.
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
excitation voltage leads. However, there will be a voltage loss on the supply
