(External load: 5k to 1MΩ)
4mA to 20mA DC
(External load: 500Ω or less)
Offset Impossible to change Impossible to change
Gain
Digital input 12 bits, binary
Resolution 2.5mV(10V×1/4000) 4μA(16mA×1/4000)
Overall accuracy
Ambient temperature:
25±5°C±0.5%(±50mV) for 10V full scale ±0.5%(±80μA) for 16mA full scale
Ambient temperature:
0 to 55°C±1.0%(±100mV) for 10V full scale ±1.0%(±160μA) for 16mA full scale
Reference
If the external load resistance (Rs) is less than
5kΩ, the accuracy increases as shown in the
following formula: (Increase: 100 mV per 1%) -

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 inputs.
• Channels are not insulated from each other.
