Analog output 
range

0V to 10 V DC

(External load: 2k

Ω to 1MΩ)

4mA to 20mA DC

(External load: 500

Ω or less)

Digital input

12 bits, binary

11 bits, binary

Resolution

2.5mV(10V/4000)

μA(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 2k

Ω.

If external load resistance becomes larger
than 2k

Ω, the output voltage will increase

slightly.
When the load is 1M

Ω, 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)

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.

Numbers of I/O 
points occupied

0 point (This number is not related to the maximum number of input/output points of the PLC.)
