9.5 Using as a Converter
This instrument can be used as a simplified converter.
Converts each input value (thermocouple, RTD, DC voltage and current inputs) to ‘4 to 20 mA DC’,
and outputs it.
When OUT1 is Direct current output, the controller can be used as a converter.
Select ‘Converter’ in [Controller/Converter] in Engineering mode.
Factory default value is Controller.
When this instrument is switched from controller to converter, values in the table below (Table 9.5-1)
are automatically set. The SV Display indicates nothing.
When this instrument is switched from converter to controller, the PV Display indicates for
1 second, and factory default values are set.
