Description
The APD 2067 DuoPak accepts one AC voltage or current input
and one frequency input and 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.
Output Sink/Source Versatility
Standard on the APD 2067 are 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 2067
Calibration
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 corresponding minimum
output signal. Example: for 4-20 mA output, set the Zero control
to 4 mA.
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, set the Span control to 20 mA.
5. Repeat adjustments for both output channels for maximum
accuracy.
Ch. 2 Sensitivity Adjustment
This multi-turn potentiometer provides an adjustable threshold
level that the incoming signal must overcome before an output can
be produced. This is used to limit noise and minimize false input
signals that may cause erroneous readings.
Fully clockwise: (max. sensitivity), input threshold is ±25 mV.
Fully counterclockwise: (min. sensitivity), input threshold is ±2.5 volts.
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. 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 operation or
a manual override. See wiring diagram at right.
Operation
The APD 2067 accepts one AC voltage or current input and one
frequency input and 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 inten-
sity 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 electrician
or instrumentation engineer. See diagram for terminal designa-
tions and wiring examples. Consult factory for assistance.
WARNING! Avoid shock hazards! Turn signal input, output, and
power off before connecting or disconnecting wiring, or removing
or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un électricien
ou ingénieur en instrumentation qualifié. Voir le diagramme 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 mod-
ule. Typical voltage may be 9-24 VDC at your device's terminals if
it provides power to the loop.

Any polarity may be used for an AC input. A transmitter DC power
supply is available at terminals 22 and 23, but is not commonly
used with an AC input.
Input 2, Frequency
The input range is pre-configured at the factory. No input calibra-
tion is necessary. The frequency input is compatible with most
types of sensors that product a minimum 100 mV amplitude
change and a minimum 5 microsecond pulse width. A 15 VDC
supply is available to power the sensor if required. Always refer to
the sensor manufacturer's data sheet to determine supply voltage
compatibility and proper wiring.

Mounting to a DIN Rail
Install module vertically on a 35 mm DIN rail in a protective enclo-
sure away from heat sources. Do not
block air flow.
1. Tilt front of module down and posi-
tion the lower spring clips against the
bottom edge of DIN rail.
2. Push front of module upward until
upper mount snaps into place.
Removal
Avoid shock hazards! Turn signal
input, output, and power off.
1. Push up on bottom back of module.
2. Tilt front of module downward to
release upper mount from top edge
of DIN rail.
3. The module can now be removed
from the DIN rail.

Sensor Load
The frequency signal input is capacitively coupled to prevent any
DC in the input. Some sensors, typically those without an internal
load resistor, require a resistive load in order to function.
The resistor value may be specified by the sensor manufacturer
as the "minimum resistive load" or calculated from the sensor
manufacturer's specified "load current range".
The 15 VDC power supply is capable of providing 25 mA. A load
current range of 3 mA to 25 mA would typically use a 5 kΩto 500
Ωresistor.
Module Power Terminals
Check label for module operating voltage to make sure it matches
available power. The power supplies are fuse protected and the
unit may be returned to API for fuse replacement.
When using DC power, either polarity is acceptable, but for
consistency, wire positive (+) to terminal 25 and negative (–) to
terminal 28.
