5.2 Power supply specification and others
5.3 Defining gain and offset
Item Content
Analog circuits 24V DC ±10% 50mA (Internal power supplied from the main unit)
Digital circuits 5V DC 20mA (Internal power supplied from the main unit)
Isolation
Photo-coupler isolation between analog and digital circuits.
No isolation between analog channels.
Number of occupied
I/O points
The blocks occupies either 8 input or output points
(can be either inputs or outputs)
Item Voltage input Current input
Range of analog input
At shipping, the unit is adjusted to a digital range of 0 to 4000 for an analog
voltage input of 0 to 10V DC. When using an FX2N-2AD for current or
differing voltage inputs except 0 to 10V DC, it is necessary to adjust the
offset and gain.
0 to 10V DC, 0 to 5V DC
(input resistance 200KΩ)
Warning-this unit may be damaged
by an input voltage in excess of
-0.5V, +15V DC
4 to 20mA (input resistance 250Ω)
Warning-this unit may be damaged by
an input current in excess of
-2mA, +60mA
Digital output 12bit
Resolution
2.5mV:10V/4000(At shipment)
Change depending on the input
characteristic.
4µA: (20-4)A/4000
Change depending on the input
characteristic.
Integrated accuracy ±0.1V ±0.16mA
Processing time 2.5ms/1 channel (synchronized to the sequence program)
Input characteristics
The input characteristic is the same for each channel.
