4-2-1. D/A converter

The D/A converter allows for analog output that corresponds
to the unit indicator value.
The D/A output circuit is isolated from the main unit circuit.
The analog output range is either 0–±10V voltage output or
4–20mA current output. Set the maximum voltage output
between ±1 V and ±10 V in 1V steps using the D/A max. volt-
age setting.
Analog output from zero (0 V, 4 mA) to full scale (±10 V, 20 mA)
can be achieved according to the digital values set using D/A
Zero and D/A full scale settings.
The zero point and full scale cannot be changed separately for
current output and voltage output.
D/A output is synchronized to the sampling frequency.
The following are examples of when "D/A MAX. VOLTAGE" is
set to 10V.
