SCHEMATIC CIRCUITRY & CONNECTION DIAGRAM
OPERATION DIAGRAM
The diagram below shows an example of I/O characteristics as specified in Table 1.
The split-range operations can be specified when ordering, by using Ordering Information Sheet, or programmed by the user using PC Configurator Software. Please refer to Users Manual for the PC Configurator for more information.
1) Two pairs of input and output in % define each split I/O range.
Proportional (positive) or inverted (negative) characteristics can be specified.
2) High and low limits for each output can be specified independently within the full-scale range.
3) Fixed output value for each output can be specified independently in advance.
These outputs are provided when the contact input is closed or opened (predefined).
H limit ≥ Fixed output ≥ Low limit
4) Applying the fixed output or not can be specified independently for each output.
In the figure, fixed output is applied to the output 2 with contact input. The solid line shows the function when contact input is shorted. The chain double-dashed line shows the function when contact input is opened.
