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

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