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.
