range
0V to 10 V DC
(External load: 5kΩ to 1MΩ)
4mA to 20mA DC
(External load: 500Ω or less)
Digital input 12 bits, binary
Resolution 2.5mV(10V/4000) 4µA(16mA/4000)
Total accuracy
• ±0.5% (±50mV) for full scale of 10 V (when
ambient temperature is 25°C±5 °C)
• ±1.0% (±100mV) for full scale of 10 V (when
ambient temperature is 0°C to 55°C)
If the external load resistance (Rs) is less than
5kΩ, the value calculated from the following
formula will be added:
(Addition will be 100mV per 1%.)
• ±0.5% (±80µA) for full scale of 16mA (when
ambient temperature is 25°C±5°C)
• ±1.0% (±160µA) for full scale of 16mA
(when ambient temperature is 0°C to 55 °C)
D/A conversion
time
200µs (The data will be updated at every scan time.)

Output
characteristics
Insulation method
• The photo-coupler is used to insulate the analog output area from the PLC.
• The DC/DC converter is used to insulate the driving power supply line from the analog
output area.
• Channels are not insulated from each other.
Numbers of I/O
occupied points
0 point (This number is not related to the maximum number of input/output points of the PLC.)
