1 When the voltage of the external power supply is less than 22.85V DC, the analog output current and the
external load resistance value are as follows.
REMARK
Refer to the user's manual for the CPU module being used for the general
specifications for the D/A converter module.
3.1.2 I/O conversion characteristics
I/O conversion characteristics are used for converting the digital value written from the
programmable controller CPU to an analog output value (voltage or current output),
and represented by inclined straight lines when offset and gain values are included.
Offset value
The offset value is the analog output value (voltage or current) when the digital input
value set from the programmable controller CPU is 0.
Gain value
The gain value denotes the analog output value (voltage or current) when the digital
input value set from the programmable controller CPU is
4000 (in normal resolution mode),
12000 (when 1 to 5V, 0 to 5V, 4 to 20 mA, 0 to 20 mA or the user range setting is
selected in high resolution mode),
16000 (when -10 to 10V is selected in high resolution mode).
