11.2.3 Two-Wire Connection of Current Sensors

You can use module 464-8MD11 for the two-wire connection of current sensors.
Figure 11-4 shows the two-wire connections of current sensors.
Figure 11-4. Two-Wire Connection for Current Sensors (6ES5 464-8MD11)
11.2.4 Connection of Two-Wire and Four-Wire Transducers
Use the 24-V inputs 1 and 2 of analog input module 464-8ME11 to supply the two-wire transducers.
The two-wire transducer converts the supplied voltage to a current of 4 to 20 mA.
For wiring connections, see Figure 11-5.
