Wiring schemes
Three wiring schemes are available for each application, depending on the type of
measurement.
Table 9- 4 Wiring scheme of SM 336; AI 6 x 13 Bit
Wiring scheme Measurement type Range Channels Abbreviation in
HW Config
A Current measurement with
2-wire transducer
4 to 20 mA 0 to 5 2DMU
B Current measurement with
4-wire transducer
4 to 20 mA
0 to 20 mA*
0 to 5 4DMU
C Voltage measurement* 0 V to 10 V 0 to 3 V
* Current measurement 0 to 20 mA and voltage measurement are only supported in standard mode.
Note
In the wiring schemes below, the connections to the reference point of the measuring circuit
M
ANA
are represented by a dashed line. This means these connections are recommended
options (see chapter "Properties, front view, wiring diagram and block diagram (Page 184)").
A dashed connectio
n between two or four sensors indicates that these sensors measure the
same process variable.
