Connecting the Field Wiring
Wiring Guidelines
Your company may have guidelines for wiring and cable installation. If so, check the guidelines
before beginning 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 F2-08DA-2 requires an external power supply for the field. The module requires 24VDC,
at up to 140mA current. The DL205 bases have internal 24VDC power supplies that provide
up to 300mA of current. This power source could be used instead of a separate power supply
if only a few analog modules are being used. If a separate power supply is to be used, choose
one that meets the power requirements of the application.
WARNING: If the internal 24VDC base power is used, be 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
equipment damage.
