D/A converter
■
Current output (DAI option)
This converter is used to obtain an analog output which is linked with the indicated value of the
F331.
The range of the analog output is from 4 to 20mA.
An analog output from 4mA to 20mA can be obtained with respect to any digital values set by the
D/A zero scale setting and the D/A full scale setting functions.
The output circuit and the main circuit are isolated.
Current output:
4 to 20mA (load resistance; 500
Ω
or less)
D/A conversion speed:
300times/sec.
Resolution:
1/10000
Over range:
2.4 to 21.6mA
Zero drift:
Within 0.5
μ
A/
℃
Gain drift:
Within 50ppm/
℃
Non-linearity:
Within 0.05%FS
* Not including the drift of the analog input section
Connector:
M3 screw type terminal block (two-pole)
* Compatible solderless terminal within 5.9mm
Tightening torque
0.6N•m
Current output terminals
Terminals for obtaining current signal.
4 to 20mA can be obtained.
Gain adjustment trimmer
For fine adjustment of gain. Trimmer
adjusts output to 20mA for full scale.
Adjustment can also be made by using
the fixed output mode.
Zero adjustment trimmer
For fine adjustment of zero. Trimmer
adjusts output to 4mA for zero scale.
Adjustment can also be made by using
the fixed output mode.
