Voltage output signals extraction method
Connect an external device (input resistance
2k
Ω
or more) to VOL. and GND of the F325
before using.
D/A zero/gain setting
D/A converter of the F325 sets an indicated
value outputting 0V (D/A zero setting value)
and an indicated value outputting 10V (D/A full
scale setting value) respectively to obtain
analog output. Input of each setting value is
implemented in D/A zero full scale setting.
●
Setting sample
D/A output mode............................ 0 (linked with indicated values)
D/A zero setting ............................. 00100
D/A full scale setting ..................... 02100
Caution
●
D/A converter voltage output is optional.
●
Do not apply voltage from outside. This will cause damage.
●
Do not short-circuit voltage output. This may cause failure.
Also, connecting capacity load may cause oscillation.
