(2) Accuracy of current output
For current output, accuracy is relative to 20mA.
Analog output is provided at the accuracy of within ±0.2% (±40µA) when the
operating ambient temperature is 25±5°C, or within ±0.4% (±80µA) when the
operating ambient temperature is 0 to 55°C.

3.3.5 Conversion speed
Conversion speed indicates time required to read the digital output value written to the
buffer memory, perform D/A conversion, and then output the specified analog value.
Conversion speed per channel of the AJ65SBT-62DA is 1ms.
Due to the data link processing time of the CC-Link system, there is a transmission
delay until the D/A conversion value is read actually.
For the data link processing time, refer to the user's manual of the master module
used.
Example) Data link processing time taken in the asynchronous mode when the master
module is the QJ61BT11 (normal value)
[Calculation expression]
SM+LS×1+remote device station processing time
SM: Scan time of master station sequence program
LS : Link scan time
Remote device station processing time: (Number of channels used+1*) × 1ms
