Determining Power Requirements
The module receives its power through the SLC 500 chassis backplane from the
+5V dc/+24V dc chassis power supply. The +5V dc backplane supply powers the
SLC circuitry, and the +24V dc backplane supply powers the module analog
circuitry. The maximum current drawn by the module is shown in the table below.
Add the values shown in the table above to the requirements of all other modules
in the SLC chassis to prevent overloading the chassis power supply. Refer to your
controller’s User Manual for power supply loading calculations and worksheets.
Using an External 24V dc Power Supply (optional)
The jumper, J4, is located in the bottom right corner of the module’s circuit board
next to the power supply.

when Using External 24V dc Power Supply(1)
(1) The 1746-NO8I and 1746-NO8V output modules can use an external 24V dc power supply to reduce backplane loading. To
use an external 24V dc power supply, you must set your module’s jumper J4 as indicated in the following section. To comply
with the U.L. regulation, the external power supply must be rated N.E.C. Class 2. Do not use the 24V dc user power terminal
on the chassis power supply to power the analog output module.
NOTE: The external 24V dc power supply terminal block ground connection (DC COM) is connected to the SLC power supply
ground.

•With the jumper in the 1-2 shorted position, the module draws all of its
power from the backplane of the SLC system.
•With the jumper in the 2-3 shorted position, the module draws its 24V dc
power from the external power supply; however, the module still draws its
5V dc power from the backplane.
Important Notes about Using an External 24V dc Power Supply
ATTENTION
!
Before setting the jumper, all system power must be turned
off. This includes the chassis power as well as any external
24V dc power supply.
IMPORTANT If the module is configured to use an external 24V dc power
supply, the supply must be turned on for the module to
operate. If the external 24V dc power supply is turned off, the
module’s outputs will be turned off, and the module’s
processor will be reset until power is restored.
The module’s LEDs will flash the 24V Power Fail blink code.
See the troubleshooting section of the SLC 500 8-Point Analog
Output Modules User Manual, publication 1746-UM026 for
more information.
IMPORTANT Do not use the 24V dc user power terminal on the chassis
power supply to power the analog output module.

Installation
Install the SLC 500 system in a properly rated (i.e., NEMA) enclosure. Make sure
that the SLC 500 system is properly grounded.
Choosing a Slot in the Chassis
Two factors determine where the analog module should be located in the chassis:
ambient temperature and electrical noise. Consider the following conditions when
selecting a slot for an analog module. Position the module:
•in a slot away from an ac or high voltage dc modules
•in the chassis closest to the bottom of the enclosure where the SLC 500
system is installed
•away from the chassis power supply if installed in a modular system
Prevent Electrostatic Discharge
TIP To use the advanced features of Class 3 operation, an SLC 5/02
or higher processor must be used, and the module must be
located in the local chassis or in a remote ControlNet chassis
with a 1747-ACN(R)15 adapter.
If the module is located in remote I/O chassis with a 1747-ASB
adapter, it will operate in Class 1 mode, and you must use
block transfer for configuration and data retrieval.
TIP Remember that, in a modular system, a processor or adapter
always occupies the first slot of the chassis.
ATTENTION
!
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch bus connector pins. Follow these
guidelines when you handle the module:
•Touch a grounded object to discharge static potential.
•Wear an approved wrist-strap grounding device.
•Do not touch the bus connector or connector pins.
•Do not touch circuit components inside the module.
•If available, use a static-safe work station.
•When not in use, keep the module in its static-shield box.

Remove Power
Terminal Block Removal
When installing the module in a chassis, it is not necessary to remove the terminal
block from the module. However, if the terminal block is removed, use the write-on
label located on the side of the terminal block to identify the module location and
type.
To remove the terminal block:
1. Loosen the two terminal block release screws.
2. Grasp the terminal block at the top and bottom and pull outward and down.
ATTENTION
!
Remove power before removing or installing this module.
When you remove or install a module with power applied, an
electrical arc may occur. An electrical arc can cause personal
injury or property damage by:
•sending an erroneous signal to your system’s field devices,
causing unintended machine motion
•causing an explosion in a hazardous environment
•causing permanent damage to the module’s circuitry
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.

Wiring
Preliminary Considerations
Use the following guidelines in planning the system wiring for the analog modules:
•Use Belden cable #8761 for wiring the analog modules making sure that the
drain wire and foil shield are properly earth grounded.
•Route the Belden cable separate from any other wiring. Additional noise
immunity can be obtained by routing the cables in grounded conduit.
•Ensure that the field wiring crosses AC or power cables at a right angle.
•All analog common terminals (ANL COM) are electrically connected inside
the module. ANL COM is not connected to earth ground inside the module.
•Voltage outputs are referenced to ANL COM. Load resistance for a voltage
output channel must be greater than or equal to 1K ohms.
•Current output channels source current that returns to ANL COM. Load
resistance for a current output channel must remain between 0 and 500
ohms.
ATTENTION
!
Before wiring any analog module, disconnect power from the
SLC 500 system and from any other source to the analog
module.

Publication 1746-IN026A-EN-P - July 2003
Wiring Procedure
To wire your module, follow these steps:
1. Determine the length of cable you need to connect a channel to its field
device. Remember to include additional cable to route the shield wire and
foil shield to their ground points.
2. At each end of the cable, strip some casing to expose the individual wires.
3. Trim the exposed signal wires to 50 mm (2 in.) lengths. Strip about 5 mm
(3/16 in.) of insulation away to expose the end of each wire.
4. At one end of the cable, twist the shield wire and foil shield together, bend
them away from the cable, and apply shrink wrap.
5. At the other end of the cable, cut the drain wire and foil shield back to the
cable and apply shrink wrap.
6. Connect the wires to the terminal block and field device as shown in Figure
4 on page 13. The recommended maximum terminal screw torque is 0.7 to
0.9 Nm (6 to 8 in-lb) for all terminal screws. Excessive tightening can strip
the terminal screw.
7. Repeat steps 1 through 6 for each channel on your module.

Configuration
The module operates in Class 1 or Class 3 mode. This section describes how to
configure the module for Class 1 operation. Class 1 provides basic data output with
no user scaling. No configuration is required. This mode is compatible with the
1746-NO4 module.
1. Using RSLogix 500, assign the module to a slot in the I/O Configuration.
Select the module from the displayed list. If the module is not listed, select
OTHER at the bottom of the list and enter the module’s ID code, shown
below.
2. Control each channel’s signal level using Output Words 0 through 7
(addressed O:e.0 through O:e.7, where e is the slot number). The data
values and corresponding signal levels are shown in the following table.
TIP Class 3 allows you to select data formats, scale limits, ramping,
clamping, alarming, safe state options and alarm latching. For
more information regarding these features, refer to the SLC 500
8-Point Analog Output Modules User Manual, publication
1746-UM026.
