(Note 1):The resolution in the 12-bit mode is 1/4,000. Also, the output current range in the 12-bit mode is 4 to 20 mA
for AFP0RDA4, and 0 to 20 mA for AFP0RA21/AFP0RA42.
(Note 2): The time shown in the figure below is required to reflect the values in the output device area (WY) of the
control unit as analog output values. The following figure shows the values when the range of -10 to +10V is
used.
Precautions on the characteristics of analog output
When the power to the control unit turns on or off, voltage (equivalent to 2 V) may be output for approx. 2 ms from
the output terminal. If it will be a problem on your system, take necessary measures externally to avoid the
transitional condition, e.g. turning on PLC before external devices or turning off external devices before PLC.
