Specifications Section 3-1
3. The maximum number of Analog Input Units that can be mounted to one
Rack varies depending on the current consumption of the other Units
mounted to the Rack.
4. Data Transfer with the CPU Unit
5. Input signal ranges can be set for each input.
6. Voltage input or current input are chosen by using the voltage/current
switch at the back of the terminal block.
7. The Analog Input Unit must be operated according to the input specifica-
tions provided here. Operating the Unit outside these specifications will
cause the Unit to malfunction.
8. The resolution can be set to 8,000 and the conversion time to 250
µ
s in the
DM Area (m+18). There is only one setting for both of these, i.e., they are
both enabled or disabled together.
9. The accuracy is given for full scale. For example, an accuracy of ±0.2%
means a maximum error of ±8 (BCD).
The default setting is adjusted for voltage input. To use current input, per-
form the offset and gain adjustments as required.
10. A/D conversion time is the time it takes for an analog signal to be stored in
memory as converted data after it has been input. It takes at least one cy-
cle before the converted data is read by the CPU Unit.
11. Line disconnection detection is supported only when the range is set to 1
to 5 V or 4 to 20 mA. If there is no input signal when the 1 to 5-V or 4 to 20-
mA range is set, the Line Disconnection Flag will turn ON.
