Spare point I/O configuration
UIO channels 13 through 20 are available to be configured as spare I/O points. These channels
can be configured as AI, AO, DI, or DO. In other words, the configuration and use of the UHIO
spare points is the same as regular channels configured and used Series C UIO.
For more information about the usage of the spare I/O points based on the configuration, see the
following sections.
l UIO channel configured as analog input spare point - UIO channel configured as Analog Input.
l UIO channel configured as analog output spare point - UIO channel configured as Analog
Output.
l UIO channel configured as digital input spare point - UIO channel configured as Digital Input.
l UIO channel configured as digital output spare point- UIO channel configured as Digital
Output.
ATTENTION
There are no restrictions for configuring these eight spare I/O channels. Any combination of
the four I/O types can be used for the eight spare I/O points.
Spare point panel
Honeywell recommends a solution for better configuration of the spare points. Phoenix Contact
has designed a DIN rail mountable assembly for I/O of the spare points. The following figure
illustrates the spare point panel.
