6.2 Analog Output
This unit outputs the measurement value by analog current output when outputting to the
outside.
The analog output contains three outputs, and outputs by selecting three components from
the following five components.
The output value is output in conjunction with the full scale of each measurement value.

Measurement item and analog output range: example of 4 to 20 mA output

Measurement item and analog output range: example of 0 to 16 mA output
Allocations for measurement analog output terminals are as follows.
Specifications for analog current output are as follows.
