2.2 Power Supply Specifications
2.3 Performance Specifications
Item Specifications
D/A conversion circuit
driving power
24V DC +20%-15%, 150mA
(It is necessary to connect a 24V DC power line to the terminal block.)
Interface driving power
5V DC, 15mA
(Since the internal power is supplied from the main unit of the FX Series, it is not
necessary to supply the power.)

Digital input 12 bits, binary
Resolution 2.5mV(10V/4000) 4μA(16mA/4000)
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)
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 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)

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 line from the analog output area.
• Channels are not insulated from each other.
