D3--04AD 4-Channel Analog Input
Setting the Module Jumpers
There are four jumpers located on the
module that select between 1--5V and
4--20 mA signals. The module is shipped
from the factory for use with 1--5V
signals.
If you want to use 4 -- 20 mA signals, you
have to install a jumper. No jumper is
required for 1 -- 5V operation. Each
channel range may be selected
independently of the others.

Connecting the Field Wiring
Your company may have guidelines for wiring and cable installation. If so, you should
check those before you begin the installation. Here are some general things to
consider.
S
Use the shortest wiring route whenever possible.
S
Use shielded wiring and ground the shield at the signal source.
Do not
ground the shield at both the module and the source.
S
Don’t run the signal wiring next to large motors, high current switches, or
transformers. This may cause noise problems.
S
Route the wiring through an approved cable housing to minimize the risk
of accidental damage. Check local and national codes to choose the
correct method for your application.
The D3--04AD requires a separate power supply. The DL305 bases have built-in 24
VDC power supplies that provide up to 100 mA of current. If you only have one
analog module, you can use this power source instead of a separate supply. If you
have more than two analog modules, or you would rather use a separate supply,
choose one that meets the following requirements: 24 VDC
?
10%, Class 2, 65mA
current (or greater, depending on the number of modules being used.)
