7.6.7. Notes on input level settings when increasing the output
When increasing output numbers to 8, 12 or 16 outputs by connecting two or more IM-011s, the inputs
common to each IM-011 unit must be set for the same level. Refer to the following examples.
• Eight outputs
Important: All of the above input levels must have the same setting regardless of increased input numbers.
The figure below shows the inputs of both "Address 0" and "Address 1" panels are set for the same level
when their outputs are increased.
