6.15.2 Measuring method/output type of SM 334; AI 4/AO 2 x 8/8 bit
Introduction
SM 334; AI 4/AO 2 x 8/8 Bit is not programmable.
Defining the measuring method and output type
Set the measuring method (voltage, current) by hardwiring the input channel.
Set the output type (voltage, current) by hardwiring the output channel.

6.15.3 Measuring 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 bits operates in the 0 V to 10 V and 0 mA to 20 mA measuring
ranges.
Compared 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 operates in the 0 V to 10 V and 0 mA to 20 mA measuring
ranges.
Compared to the other analog modules, the SM 334 has a lower resolution, and its analog
outputs do not have any undershoot 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
