Wiring Guidelines
Your company may have guidelines for wiring and cable installation. If so, check them before
starting the installation. Here are some general things to consider:
• Use the shortest wiring route whenever possible.
• Use shielded wiring and ground the shield at the transmitter source. Do not ground the shield at
both the module and the source.
• Do not run the signal wiring next to large motors, high current switches, or transformers. This may
cause noise problems.
• 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.
User Power Supply Requirements
The F2-08AD-1 requires at least one external power supply. The same or separate power
sources can be used for the module supply and the current transmitter supply. The module
requires 18–30 VDC, at 80 mA.
The DL205 bases have built-in 24 VDC power supplies that provide up to 300 mA of current.
This may used with the F2-04AD-1 modules instead of a separate supply if only a couple of
analog modules are being used.
It is desirable in some situations to power the transmitters separately in a location remote
from the PLC. This will work as long as the transmitter supply meets the voltage and current
requirements, and the transmitter’s minus (-) side and the module supply’s minus (-) side are
connected together.
WARNING: If using the 24 VDC base power supply, make sure to calculate the power budget. Exceeding
the power budget can cause unpredictable system operation that can lead to a risk of personal injury or
damage to equipment.
The DL205 base has a switching type power supply. As a result of switching noise,
W
3-5 counts
of instability may be noticed in the analog input data if the base power supply is used. If this is
unacceptable, try one of the following:
1. Use a separate linear power supply.
2. Connect the 24 VDC common to the frame ground, which is the screw terminal marked on the
screw terminal marked “G” on the base.
By using these methods, the input stability is rated at
W
1 count.
The F2-08AD-1 module requires 18–26.4 VDC, at 80 mA, if a external power supply is
used.
