Module Specifications

The F0-2AD2DA-2 Analog Combination module offers the following features: The analog

input and output channels are updated in one scan.

• The module has a removable terminal block which makes it
possible to remove the module without disconnecting the field
wiring.

• Analog inputs can be used as process variables for the four (4)
PID loops in the DL05 and the eight (8) PID loops in the DL06
CPUs.

• On-board active analog filtering and RISC-like microcontroller
provide digital signal processing to maintain precise analog
measurements in noisy environments.

Setting the Module Jumpers

The position of the J2 jumpers determines the input and output signal levels. You can choose
between 0–5 VDC or 0–10 VDC. The module ships with the jumpers connecting the pins.
In this position, the input and output signal level is 0–5 VDC. To select 0–10 VDC signals,
use the jumper setting chart located on the module. One or more channels can be selected for
0–10 VDC input and output signal level by removing the jumper from the connecting pins of
the appropriate channel. This will allow you to have one channel selected for a 0–5 VDC signal
and another channel selected for a 0–10 VDC signal.

WARNING: Before removing the analog module or the terminal block on the face of the module,
disconnect power to the PLC and all field devices. Failure to disconnect power can result in damage to
the PLC and/or field devices.

Wiring Guidelines

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:

• 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.

The F0–2AD2DA–2 will require an external power supply with a rating of 18.0–26.4 VDC at
30mA.

To remove the terminal block, disconnect power to the PLC and the field devices. Pull the
terminal block firmly until the connector separates from the module.

You can remove the analog module from the PLC by folding out the retaining tabs at the top
and bottom of the module. As the retaining tabs pivot upward and outward, the module’s
connector is lifted out of the PLC socket. Once the connector is free, you can lift the module
out of its slot.

Wiring Diagram

Use the following diagram to connect the field wiring. If necessary, the F0–2AD2DA–2 terminal
block can be removed to make removal of the module possible without disturbing field wiring.

Module Operation

Input/Output Channel Scanning Sequence

The DL05 and DL06 read two channels of input and two channels of output data during each
scan. The CPU supports special V-memory locations that are used to manage the data transfer.
This is discussed in more detail on the following page, “Special V-memory Locations”.

Analog Module Updates

Even though the channel updates to the CPU are synchronous with the CPU scan, the module
asynchronously monitors the analog transmitter signals and converts each signal into a 12-bit
binary representation. This enables the module to continuously provide accurate measurements
without slowing down the discrete control logic in the RLL program.

The module takes approximately 10 milliseconds to sense 95% of the change in the analog
signal. For the vast majority of applications, the process changes are much slower than these
updates.

NOTE: If you are comparing other manufacturers’ update times (step responses) with ours, please be aware
that some manufacturers refer to the time it takes to convert the analog signal to a digital value. Our analog
to digital conversion takes only a few microseconds. It is the settling time of the filter that is critical in
determining the full update time. Our update time specification includes the filter settling time.
