F2-08DA-2 AUTOMATION DIRECT

Description

The F2-08DA-2 Analog Output module
provides several hardware features:
S Supports DL230, DL240, DL250–1
and DL260 CPUs (see firmware
requirements below).
S Analog outputs are optically
isolated from the PLC logic.
S The module has a removable
terminal block, so the module can
be easily removed or changed
without disconnecting the wiring.
The F2-08DA-2 requires a separate field-side power supply. Each module requires
21.6–26.4VDC at up to 140mA current. The DL205 bases have built-in 24 VDC
power supplies that provide up to 300mA of current. If you are using only a couple of
analog modules, you can use this power source instead of a separate supply. If you
want to use a separate supply, choose one that meets the power requirements of
your application.

One count in the specification table is equal to one least significant bit of the analog data value (1 in 4096).
The F2-08DA-2 analog output requires 16 discrete output points. The module can
be installed in any slot of a DL205 system, but the available power budget and
discrete I/O points can be limiting factors. Check the user manual for your particular
model of CPU and I/O base for more information regarding power budget and
number of local, local expanison or remote I/O points.
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 load.
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 F2-08DA-2 requires a separate field-side power supply. Each module requires
21.6–26.4VDC at up to 140mA current. The DL205 bases have built-in 24 VDC

your application.
