Table 159. Maximum quantity of I/O modules
When ordering I/O modules, observe the maximum quantities according to tables below.
Note: Standard order of location for I/O modules is BIM-BOM-SOM-IOM-MIM from left to right as seen from the rear side of the IED, but can
also be freely placed.
Note: Maximum quantity of I/O modules depends on the type of connection terminals.
Note: When ordering I/O modules, observe the maximum quantities according to the table below
