When these voltages (VAC or > 31.2 VDC) are used, it may be necessary to
plan for an in-house supply segment for the following I/O modules.
Do not mount any I/O modules behind the I/O module (750-527) that is rated only
up to a field-side 31.2°VDC. Therefore, no filter modules (750-626) can be used.
Protect the new supply segment with a 24 VDC supply module (e.g., 750-613,
-601 or -610).
