Description
The APD 2006 DuoPak accepts one DC voltage or current input
and one AC voltage or current input provides two optically
isolated DC voltage or current outputs that are linearly related
to the inputs.
The input ranges and the output ranges for each channel are
independent and can be specified as required. This provides an
economical two channel solution in one device.
Typical applications include signal conversion, isolation, and
redundancy (i.e. to prevent failure of the entire loop if one
device fails), or a combination of these.
Each input signal is filtered, amplified, and then passed
through an opto-coupler to the output stages. Full 5-way
isolation (input 1, input 2, output 1, output 2, power) make
this module useful for ground loop elimination, common mode
signal rejection, and noise pickup reduction.
I/O Sink/Source Versatility
Standard on the APD 2006 is a 15 VDC loop excitation supply
for the DC input channel and 20 VDC loop excitation sup-
plies for each output channel. These power supplies can be
selectively wired for sinking or sourcing allowing use with any
combination of powered or unpowered milliamp I/O devices.
LoopTracker
API exclusive features include four LoopTracker LEDs (green
for each input, red for each output) that vary in intensity with
changes in the process input and output signals.
These provide a quick visual picture of your process loop at all
times and can greatly aid in saving time during initial startup
and troubleshooting.
Output Test
An API exclusive feature includes output test buttons for each
channel to provide a fixed output (independent of the input)
when held depressed.
Terminals are also provided to operate the test functions
remotely for each channel. This also allows use as a remote
manual override to provide a temporary fixed output if desired.
The test output level for each channel is potentiometer adjust-
able from 0 to 100% of the output span. The output test greatly
aids in saving time during initial startup and/or troubleshooting.

Instructions APD 2006
Calibration
Input and output ranges are factory pre-configured (at 24°C
±1°C). Front-mounted Zero and Span potentiometers for
each channel can be used to compensate for load and lead
variations.
1. Apply power to the module and allow a minimum 30 minute
warm up time.
2. Using an accurate calibration source, provide an input to
the module equal to the minimum input required for the
application.
3. Using an accurate measurement device for the output,
adjust the Zero potentiometer for the exact minimum output
desired. The Zero control should only be adjusted when the
input signal is at its minimum. This will produce the cor-
responding minimum output signal. For example: 4 mA for
a 4-20 mA output or –10 V for a ±10 V output.
4. Set the input at maximum, and then adjust the Span pot for
the exact maximum output desired. The Span control should
only be adjusted when the input signal is at its maximum.
This will produce the corresponding maximum output
signal. Example: for 4-20 mA output, the Span control will
provide adjustment for the 20 mA or high end of the signal.
5. Repeat adjustments for both output channels for maximum
accuracy.
Output Test Function
When the Test button is depressed it will drive the output with a
known good signal that can be used as a diagnostic aid during
initial start-up or troubleshooting. When released, the output
will return to normal.
Each Test Cal. potentiometer is factory set to approximately
50% output. Each can be adjusted to set the test output from
0 to 100% of the output span. Press and hold the Test button
and adjust the corresponding Test Cal. potentiometer for the
desired output level.
They may optionally be externally wired for remote test opera-
tion or a manual override. See wiring diagram at right.
Operation
The APD 2006 accepts one DC voltage or current input and one
AC voltage or current input provides two optically isolated DC
voltage or current outputs that are linearly related to the inputs.
Green LoopTracker®input LEDs provide a visual indication that
each signal is being sensed by the input circuitry of the module.
They also indicates the input signal strength by changing in
intensity as the process changes from minimum to maximum.
If an LED fails to illuminate, or fails to change in intensity as
the process changes, check the module power or signal input
wiring. Note that it may be difficult to see the LEDs under bright
lighting conditions.
Two red LoopTracker output LEDs provide a visual indication
that the output signals are functioning. They become brighter
as the input and each corresponding output change from
minimum to maximum.
For a current output the red LED will only light if the output loop
current path is complete. For either current or voltage outputs,
failure to illuminate or a failure to change in intensity as the
process changes may indicate a problem with the module
power or signal output wiring.

Precautions
WARNING! All wiring must be performed by a qualified electri-
cian or instrumentation engineer. See diagram for terminal des-
ignations and wiring examples. Consult factory for assistance.
WARNING! Avoid shock hazards! Turn signal input, output, and
power off before connecting or disconnecting wiring, or remov-
ing or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un élec-
tricien ou ingénieur en instrumentation qualifié. Voir le dia-
gramme pour désignations des bornes et des exemples de
câblage. Consulter l'usine pour assistance.
ATTENTION! Éviter les risques de choc! Fermez le signal
d'entrée, le signal de sortie et l'alimentation électrique avant
de connecter ou de déconnecter le câblage, ou de retirer ou
d'installer le module.
Electrical Connections
Polarity must be observed for signal wiring connections. If the
input and/or output do not function, check wiring and polarity.
Each product is factory configured to your exact input and
output ranges as indicated on the serial number label.
Outputs
For milliamp ranges determine if your devices provide power
to the current loop or if the loop must be powered by the APD
