Nokeval 7470 Serial to Analog
Converter
0412-045 Figure 17 Nokeval Serial to Analog Converters
Nokeval 7470 Serial to Analog Converter is used for converting a
predefined ASCII message to one or more voltage or mA outputs. This
kind of conversion may be required, for example, when weather
information is needed in automation systems where only voltage or
current inputs are used instead of a serial data interface. The converter
can be controlled through an RS-485 serial line.
As Nokeval converters are fully configurable, knowledge on these
devices is required before taking them into use. It is possible to add one
or more converters to a single RS-485 serial line with the QML logger.
For further details, see the applicable Nokeval user manual, available at
