Procedure
□
4. Set the analog input field power select jumpers J15 and
J16 located on the CIO-100 base (Table
PR11-2 ). These jump-
ers affect channels configured as IFP or LFP powered 4 to 20
milliampere analog inputs. Refer to Figure
PR11-1 for jumper
locations.
Figure PR11-2 shows the field power connections made with
jumpers J15 and J16.
□
5. Set the analog input channel jumpers located on the
CIO-100 base as appropriate (Table
PR11-3 ).
□
6. Remove the access cover from the left side of the I/O mod-
ule (Fig.
PR11-3 ).
□
7. Set the analog output channel jumpers as appropriate
(Table
PR11-4 ). Refer to Figure PR11-4 for jumper locations.

Table PR11-2. Analog Input Field Power Select Jumpers (Base)
Field Power J15 J16 Description
Fused AI
IFP/LFP
1
(no station)
Routes IFP/LFP field power
through the fuse in the I/O
module.
Unfused AI
LFP
2,3
(station)
Routes LFP power directly to
the base terminals. Use this
setting if stations are
connected.
NOTES :
1. This option can be selected to provide fused IFP or LFP power to the analog input channels;
however, removing the I/O module from the base will result in a loss of power to all input current
loops.
2. Use this setting if current loop power must be maintained when the I/O module is removed from
the base.
3. Use this setting if analog inputs are RFP powered.
