Applications
Description
The APD 2077 DuoPak accepts two frequency inputs and
provides two optically isolated DC voltage or current analog
outputs that are linearly proportional 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 2077 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/Manual Override
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 2077
Output Calibration
The output range is pre-configured at the factory as specified on
your order. Zero and Span potentiometers are used to calibrate
the output to compensate for load and lead variations.
1. Apply power to the module and allow a minimum 30 minute
warm up time. An accurate frequency calibration source such
as a signal generator may be required for calibration.
2. Provide an input to the module equal to the minimum input
required for the application. In the most cases this will be 0 Hz.
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 signal, the Zero control will
provide adjustment for the 4 mA or low end of the signal.
4. Set the frequency to the maximum input required for the application.
5. Using an accurate measurement device for the output, 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 out-
put signal. Example: for 4-20 mA output signal, the Span control
will provide adjustment for the 20 mA or high end of the signal.
6. Repeat adjustments for each channel for maximum accuracy.
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 a 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. They may optionally be externally wired for
remote test operation or a manual override. See wiring diagram
at right.
Each Test Cal. potentiometer can be adjusted to set the test out-
put 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.
Operation
The APD 2077 accepts two frequency inputs and provides two
optically isolated DC voltage or current analog outputs that are
linearly proportional to the inputs.
Each frequency input is capacitively coupled (to remove any DC
component at the input) to a comparator whose threshold is deter-
mined by the setting of the sensitivity control. The output from the
comparator passes through an opto-coupler to the output stage.
Green LoopTracker®input LEDs provide a visual indication that a
signal is being sensed by the input circuitry of each channel. The
LEDs illuminate when the input is sufficiently large to trigger the
input comparator depending on the input sensitivity adjustment.
They also indicate the input signal range by changing in intensity as
the frequency changes from minimum to maximum. If an LED fails
to illuminate, or change in intensity as the frequency changes, it
may indicate a problem with module power, or signal input wiring.
Note that it may be difficult to see the LEDs under bright lighting
conditions.
Red LoopTracker output LEDs provide a visual indication that the
output signals are functioning. Each becomes brighter as the input
and the corresponding output change from minimum to maximum.
For current outputs, the red LED will only light if the output loop cur-
rent 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
module. Typical voltage may be 9-24 VDC at your device's termi-
nals if it provides power to the loop.
Inputs, Frequency
The input ranges are pre-configured at the factory. No input
calibration 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.
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 kWto 500
Wresistor.
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.
