About D/A resolution
The resolution of the D/A converter is 1/10000 with respect to 4 to 20mA.
In other words, the minimum unit of voltage is:
(20 - 4mA) × 1/10000 = 1.6μA.
Also, the minimum unit of indicated value is:
(D/A full scale - D/A zero scale) × 1/10000.
■D/A zero and full scale
Set the D/A zero and full scale of the F331.
* Please be sure to set up zero scale < full scale.
■D/A output mode
Set the D/A output mode of the F331.
Linked with indicated value
Analog output linked with indicated value.
When the indicated value is held, the held value is outputted even if the sensor input signal changes.
Not linked with indicated value
Scaled analog output linked with sensor input.
Even if the indicated value is held, an output is made according to the changes in sensor input
signal.
Zero scale fixed output
A fixed output of 4mA is made.
Full scale fixed output
A fixed output of 20mA is made.
