Before installing and wiring the module, you may
need to change the internal jumper setting. The
module has one jumper, located in the open
cutout at the rear of the housing. When the
jumper is installed (which is the factory default
setting), the module operates in 0–5VDC mode
for all eight channels. When the jumper is
removed, the module operates in 0–10VDC
mode. When removed, store the jumper by
placing it over one terminal as shown below to
prevent losing it.
Installed = 0–5VDC Mode
Removed = 0–10VDC Mode
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 module or the power
supply return (0V). Do not ground the shield at both the module and the
transducer.
S
Do not 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 F4–08DA–2 requires a field-side power supply. The module requires 21.6 –
26.4 VDC, Class 2, 150mA max. current.
The D4–430/440/450 CPUs, D4–RS Remote I/O Controller, H4–EBC, and D4–EX
Expansion Units have built-in 24 VDC power supplies that provide up to 400mA of
current. You may use one of these instead of a separate supply if there is only a
couple of analog modules. The current required is 150mA max.: eight outputs
driving 1kΩ loads to 10V (10mA x 8); plus 70mA for the module's internal circuitry.
Each channel in use must have a load impedance of 1kΩ to 10kΩ. Unused
channels must be left disconnected.
WARNING: If you are using the 24 VDC base power supply, make sure you
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.
