Voltage output Current output
Analog output
range
0V to 10 V DC
(External load: 2kΩ to 1MΩ)
4mA to 20mA DC
(External load: 500Ω or less)
Digital input 12 bits, binary 11 bits, binary
Resolution 2.5mV(10V/4000) 8μA(16mA/2000)
Total accuracy
• ±0.5% (±50mV) for 10V full scale
(when ambient temperature is 25°C±5 °C)
• ±1.0% (±100mV) for 10V full scale
(when ambient temperature is 0°C to 55°C)
Shipment adjustment is carried out by external
load resistance 2kΩ.
If external load resistance becomes larger
than 2kΩ, the output voltage will increase
slightly.
When the load is 1MΩ, the output voltage
becomes about 2% higher than the correct
value.
• ±0.5% (±80μA) for 16mA full scale
(when ambient temperature is 25°C±5°C)
• ±1.0% (±160μA) for 16mA full scale
(when ambient temperature is 0°C to 55 °C)
D/A conversion
time
60μs (The data will be updated at every scan time.)

Output
characteristics
Caution:
An area of dead band is located in the region
of 0V. Therefore the output analog value may
not represent the digital value accurately.
Insulation method • The analog output area is not insulated from the PLC.
