Description:
The expansion power supply passes 24 VDC field power to the I/O modules to the right of it. The expansion power supply extends the backplane bus power for up to 17 I/O modules to the right of the supply and creates a new field voltage partition segment for drivign field devices. The expansion power supply separates field power from I/O modules to the left of the unit, effectively providing functional and logical partioning for the following:

  • Separate field power between input and output modules.
  • Separate field power to the analog and digital modules.
  • Group modules to perform a specific task or function.

    • The dark-gray color of the expansion power supply allows for easy visual inspection and indentification.

    Use multiple expansion power supplies with POINT I/O adapters to asssembly a full system. With any POINT I/O adapter, use an expansion power supply to add additional modules in 4-17 module increments, for a total of 63 I/O modules.
