Four-wire transducer
Figure 11-4. Connection for Four-Wire Transducers (6ES5 464-8ME11)
Four-wire transducers require their own power supply.
Connect the "+" pole of the four-wire
transducer to the corresponding "-" pole of the terminal block (a connection technique that is the
opposite of the two-wire transducer).
Connect negative terminals of the four-wire transducer to terminal two of the terminal block.
Inputs 4, 6, 8, and 10 of the analog input module 464-8ME11 are connected internally via shunt
resistors. Because of the internal shunt resistors, broken wire signalling is not possible.
