Wiring scheme B, current measurement 4 to 20 mA with 4-wire transducer for application 3
You can interconnect six process signals with an analog module. Sensor supply V
S
is
provided by the analog module for 6 channels. The sensors can also be connected to an
external sensor supply (see figure
External sensor supply, 4-wire transducer for
SM 336; AI 6 x 13Bit
in chapter "Properties, front view, wiring diagram and block diagram
(Page 184)").
