High-speed Analog Input Units
Description of Items on Data Sheet of the High-speed Analog Input
Units
The meanings of the items on the data sheet of the High-speed Analog Input Units are explained in
the table below.
Item
Description
Unit name
The name of the Unit.
Model
The number of the Unit.
External connection termi-
nals
The type of terminal block and connector that is used for connecting the Unit.
The number of terminals on the terminal block is also described when a
screwless clamping terminal block is used.
I/O refreshing method
The I/O refreshing methods that are used by the Unit. Only synchronous I/O
refreshing is available.
Indicators
The type of indicators on the Unit and the layout of those indicators.
An-
alo
g
in-
put
sec-
tion
Number of points
The number of analog input points provided by the Unit.
Input method
The analog signal input method provided by the Unit. Only differential input
method is available.
Input range
The input range of the Unit.
Input conversion
range
The conversion range of converted values for the full scale of the Unit. Input
converted values range is fixed to the conversion limit value.
Absolute maximum
rating
The maximum value of analog input signals of the Unit. If a signal exceeding
this range is input, the Unit may be damaged.
Input Impedance
The input impedance of the Unit.
Resolution
The resolution of converted values of the Unit.
Overall accuracy
The analog input conversion accuracy of the Unit. It is defined under the con-
ditions of 25°C and 0 to 55°C.
Conversion time
The time required to convert analog input signals of the Unit to the converted
values.
Trig

put
sec-
tion
Number of points
The number of trigger input points provided by the Unit.
Internal I/O common
The polarity of the input devices that are connected to the Unit. NPN connec-
tion and PNP connection are available.
Rated input voltage
The rated input voltage and range of the Unit.
Input current
The input current at the rated voltage of the Unit.
ON voltage/ON current
The input voltage in which the Unit input turns ON, and corresponding input
current.
OFF voltage/OFF cur-
rent
The input voltage in which the Unit input turns OFF, and corresponding input
current.
ON/OFF response time
The delay time for which the status change of the input terminals reaches the
internal circuit of the Unit. The input filter time below is not included. It is de-
scribed according to the ON/OFF sequence.
Input filter time
The filter time when the status of the internal circuit is read as the data to the
internal of the Unit.
It is the same for both ON/OFF. The filter time to be set by the Support Soft-
ware is described.
Dimensions
The dimensions of the Unit. They are described as W × H × D. The unit is
"mm".
