Item Description
Number of points The number of load cell input points provided by the Unit.
Conversion cycle The time required to convert load cell input signals of the Unit to measurement values.
Load cell excitation
voltage
The excitation voltage that is supplied from the Unit to the load cell. The output current of the load
cell excitation voltage that the Unit can supply is also listed.
Input range The input range of the Unit.
I/O refreshing method The I/O refreshing methods that are used by the Unit.
Free-Run refreshing, synchronous I/O refreshing and task period prioritized refreshing are avail-
able.
In the following table, the following abbreviations are used.
Free: Free-Run refreshing
Sync: Switching synchronous I/O refreshing and Free-Run refreshing
