Procedure
□
4. Set the analog input field power select jumpers J17 and
J18 located on the AIN-120 base (Table PR6-2). These jumpers
affect channels configured as IFP or LFP powered 4 to 20 milli-
ampere inputs. Refer to Figure PR6-1 for jumper locations.
Figure PR6-2 shows the field power connections made with
jumpers J17 and J18.
□
5. Set the input channel jumpers located on the AIN-120 base
(Table PR6-3). Refer to Figure PR6-1 for jumper locations.

Field Power J17 J18 Description
Fused AI
IFP/LFP

Routes IFP/LFP field power
through the fuse in the I/O
module.
Unfused AI
LFP
2,3
Routes LFP power directly to
the base terminals.
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 in a nonredundant application 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 in nonre dundant app lications.
3. Use this setting if analog inputs are RFP powered. Use this option if stations are connected.
