Description
The APD 7580 accepts a frequency input and provides an
optically isolated DC voltage or current output that is linearly
related to the input.
Common applications include frequency to DC conversions
from frequency output type devices such as rotary encoders,
magnetic pick-ups, proximity sensors, variable speed drives,
and flow meters. For PLCs that do not have analog outputs,
often the pulse rate of a discreet output can be programmed to
vary. By connecting the APD 7580 to this output, a proportional
analog signal can be generated. A 15 VDC power supply is
provided to power the sensor input, if required.
Full 3-way isolation (input, output, power) makes this module
useful for ground loop elimination, common mode signal rejec-
tion or noise pickup reduction.
The APD 7580 input and output can be field-configured via
external rotary and slide switches. Common ranges are on
the module label. Many additional combinations are possible.
Consult the factory for assistance with special ranges.
Sink/Source Versatility
For maximum versatility the output can be selectively wired for
sinking (unpowered) or sourcing (powered) milliamp output.
The 20 VDC loop excitation supply can be used to power a mil-
liamp current loop if required. The output can also be wired for
an externally powered loop.
LoopTracker
API exclusive features include two LoopTracker LEDs (green for
input, red for 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/or troubleshooting.
Output Test
An API exclusive feature includes the test button to provide a
fixed output (independent of the input) when held depressed.
The test output level is potentiometer adjustable from 0 to
100% of output span.
The output test button greatly aids in saving time during initial
startup and/or troubleshooting.
All models are field rangeable

Precautions
WARNING! All wiring must be performed by a qualified electri-
cian or instrumentation engineer. See diagram for terminal
designations and wiring examples. Consult factory for assis-
tance.
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.
Range Selection
See table below to select I/O ranges for your application. It is
generally easier to select ranges before installation.
The module side label lists common ranges.
See the model/serial number label for module information,
options, or if a custom range was specified.
For ranges that fall between the listed ranges use the next
highest setting and trim the output signal with the zero and
span potentiometers.
Input Switch Settings
Rotary and slide switches on the side of the module are used to
select input and output ranges. see table below.
1. Set the input range slide switch Ato either "H" or "L"
depending on input frequency range.
For frequencies from 0-100 Hz thru 0-1500 Hz, switch Ais
placed in the "L" position.
For frequencies from 0-2000 Hz thru 0-30 kHz, switch Ais
placed in the "H" position.
2. Set input range rotary switch Bto match your input fre-
quency range.
Output Switch Settings
1. Set output range Cand output offset Dto match your output
range.
2. Set the output slide switch Eto current "I" or voltage "V"
depending on output type.

Electrical Connections
Polarity must be observed for input and output wiring connec-
tions. If the input and/or output do not function, check switch
settings and wiring polarity.
*Do not make any connections to unused terminals or use
them as wiring junctions for external devices. This may cause
permanent damage to the module!
Input
The APD 7580 is compatible with most types of sensors as
long as the waveform produces 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 deter-
mine supply voltage compatibility and proper wiring.
Sensor Load
The signal input of the APD 7580 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.
For NPN sensors use an external resistor across terminals 2
and 3 if required.
For PNP sensors use an external resistor across terminals 2
and 4 if required.
Output
Polarity must be observed when connecting the signal output to
the load. See the table below and the wiring diagrams at right.
The APD 7580 output can be wired to provide power to drive
a current loop. Determine if your receiving device provides
power to the current loop or if the loop must be powered by
the APD module.
Use a multi-meter to check for voltage at your device's input
terminals. Typical voltage may be 9-24 VDC if it provides power
to the loop.
Module Power
Check model/serial number label for module operating voltage
to make sure it matches available power.
When using DC power, either polarity is acceptable, but for
consistency with similar API products, positive (+) can be wired
to terminal 13 and negative (–) can be wired to terminal 16.

Output Calibration
Input and output ranges, if specified on your order, are factory
pre-configured (at 24°C ±1°C).
Front-mounted Zero and Span potentiometers are used to
calibrate the output to compensate for load and lead variations.
Note: Perform the following calibration procedure any time
switch settings are changed.
1. Apply power to the module and allow a minimum 20 minute
warm up time.
2. Using an accurate frequency calibration source such as a
signal generator, provide an input to the module equal to
the minimum input required for the application.
In the most cases the minimum input signal will be 0 Hz.
3. Set the frequency calibration source equal to the maximum
input required for the application. This will typically be
within 10% of the range selected with switches A and B.
4. 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 correspond-
ing maximum output signal.
For example: 4 mA for a 4-20 mA output or –10 V for a
±10V output.
5. Repeat adjustments 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.
When fully clockwise (maximum sensitivity), the input thresh-
old is typically ±25 mV.
In the fully counterclockwise position (minimum sensitivity), the
input threshold is typically ±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.
The Test Cal. potentiometer is factory set to approximately
50% output. It 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 Test Cal. potentiometer for the desired output level.
Operation
The APD 7580 accepts a frequency input and provides an
optically isolated DC voltage or current output that is linearly
related to the input.
The frequency input to the APD 7580 is capacitively coupled
(to remove any DC component at the input) to a comparator
whose threshold is determined by the setting of the sensitivity
control. The output from the comparator passes through an
opto-coupler to the output stage.
The green LoopTracker®input LED provides a visual indica-
tion that a signal is being sensed by the input circuitry of the
module. The LED illuminates when the input is sufficiently
large to trigger the input comparator depending on the input
sensitivity adjustment.
It also indicates the input signal range by changing in intensity
as the frequency changes from minimum to maximum. If the
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 light-
ing conditions.
The red LoopTracker output LED provides a visual indication
that the output signal is functioning. It 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
current path is complete. For either current or voltage outputs,

process changes may indicate a problem with the module
power or signal output wiring.
