Overall accuracy
Ambient temperature:
25±5°C±0.5%(±100mV) for 20V full scale ±0.5%(±100μA) for 20mA full scale
Same accuracy for 4mA to 20mA output
Ambient temperature:
0 to 55°C±1.0%(±200mV) for 20V full scale ±1.0%(±200μA) for 20mA full scale
Same accuracy for 4mA to 20mA output
Reference Does not include any load fluctuation. -
Time required for D/A
conversion 2.1ms (The number of selected channels will not affect this value.)
Output characteristics
Insulation method
The photocoupler is used to insulate the analog output area from the PLC.
The DC/DC converter is used to insulate the power supply from the analog output.
Channels are not insulated from each other.
Number of I/O points
occupied 8 points (Taken from either the input or output points of the PLC.)
