6.16.3 Measurement and output ranges of SM 334; AI 4/ AO 2 x 8/8 bit
Measuring ranges
SM 334; AI 4/AO 2 x 8/8 Bit provides the 0 V to 10 V and 0 mA to 20 mA measuring ranges.
By contrast to the other analog modules, the SM 334 has a lower resolution and no negative
measuring ranges. Make allowances for this feature when reading the measured value
tables
Analog value representation in the ± 1 V to ± 10 V measuring ranges and Analog
value representation in the 0 mA to 20 mA and 4 mA to 20 mA measuring ranges
.
Output ranges
SM 334; AI 4/AO 2 x 8/8 Bit provides the 0 V to 10 V and 0 mA to 20 mA output ranges.
Compared to the other analog modules, the SM 334 has a lower resolution, and its analog
outputs do not have any overshoot ranges. Make allowances for this feature when reading
the tables
Analog value representation in the 0 V to 10 V and 1 V to 5 V output ranges and
Analog value representation in the 0 mA to 20 mA and 4 mA to 20 mA output ranges .
6.16.4 Additional information on SM 334; AI 4/AO2 x 8/8 Bit
Unused channels
Always short-circuit unused input channels, and connect these to M
ANA
. This optimizes
interference immunity of the analog input module.
Leave unused output channels open.
