Example 1: Isolating Field Power Segments
This power supply example uses a 1734-EP24DC expansion power supply and
1734-FPD field power distributor to illustrate mixing standard POINT I/O and
safety POINT Guard I/O modules, while creating separate groups for input and
output modules, as well as digital and analog modules.
Example 2: POINT Guard I/O Used with AC I/O Modules
This power supply example uses 1734-EP24DC and 1734-EPAC expansion
power supplies to illustrate mixing standard POINT I/O and safety POINT
Guard I/O modules, while creating a separate power group for AC I/O modules.
