13-2.D/A converter
■Voltage output (DAV option)
This converter is used for obtaining an analog output linked with indicated values of the F325.
The analog output range is voltage output -10 to +10V.
Analog output of 0V to ±10V can be obtained with respect to arbitrary digital values set by
D/A zero setting and D/A full scale setting functions.
Also, the output circuit and main unit circuit are isolated.
Voltage output: -10 to +10V (input resistance 2kΩ or more)
D/A conversion rate: According to sampling rate
Resolution: 1/10000
Over range: -11.0 to +11.0V
Zero-adjust range: Approx. -1.0 to +1.0V (at the time of zero output)
Gain adjust range: Approx. 9.5 to 10.5V (at the time of full-scale output)
Zero drift: 0.6mV/℃ or less
Gain drift: 50ppm/℃ or less
Non-linearity: 0.05％FS or less
* Drift of analog input is not included
Output connector: M3 screw type terminal block (two poles)
* Conforming crimping terminal 5.9mm or less
Tightening torque 0.6N・m
Zero adjust trimmer
This trimmer adjusts voltage output to zero
when a value registered in D/A zero setting is
displayed.
The zero adjust range is approx. -1.0 to +1.0V
(at the time of zero output).
Gain adjust trimmer
This trimmer adjusts voltage output to a
display registered in D/A full scale setting.
The gain adjust range is approx. 9.5 to 10.5V
(at the time of full-scale output).
Voltage output terminal
This terminal is used for
extracting voltage signals.
VOL. is signal, and GND is ground.
0 to ±10V can be obtained.
VOL. GND ZERO GAIN
