Description
The APD 4008 accepts a resistance input from potentiometer,
slidewire, linear position, displacement, or rotational devices
and provides an optically isolated DC voltage or current output
that is linearly related to the potentiometer position.
The APD 4008 will accept any potentiometer with a value of
0-100 Ωthrough 0-1 MΩwithout recalibration and without
affecting accuracy. The APD 4008 output can be field-con-
figured via external rotary and slide switches. Offsets and/or
input ranges other than 0 to 100% of the potentiometer range
can also be selected.
The full 3-way (input, output, power) isolation makes this mod-
ule useful for ground loop elimination, common mode signal
rejection or noise pickup reduction.
Sink/Source Output
The APD 4008 has a 20 VDC loop excitation supply for the
output. This power supply can be used to power a passive mA
device. If not required, the APD 4008 output can be wired as
a passive output. Sinking/sourcing versatility allows the APD
4008 to produce a powered or unpowered mA output allowing
it to work with powered or unpowered mA devices.
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.

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 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 model/serial number label for any applicable options or
custom ranges. It is generally easier to select ranges before
wiring and installation.
See table on next page for module range settings. From the
table, find the rotary switch setting that matches your input
and output range.
For most applications 0-100% of the potentiometer range is
used. The APD 4008 can be set up to use part of the potenti-
ometer range.
Input switch Bcontrols the percent of the potentiometer range
to use.
Input switch Ccontrols the percent of the range offset from zero.
Switch Dcontrols output offset.
Make sure to set the V—I switch for voltage or current output
respectively.
Electrical Connections
Polarity must be observed for output wiring connections. If the
output does not function, check switch settings and wiring polarity.
Input
The potentiometer must be connected to all three signal input
terminals as shown. The APD 4008 utilizes a stable 1 VDC
source to excite the potentiometer.
Output
Polarity must be observed when connecting the signal output.
If your device requires a current input, determine if it provides
power to the current loop or if it must be powered by the APD
module.
Use a multi-meter to check for voltage at your device input
terminals. Typical voltage may be in the range of 9 to 24 VDC.
In this case, wire the device to module terminals 2 and 3.
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.
Calibration
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. Set the input potentiometer to its minimum value to provide
a minimum input to the module.
3. Connect an accurate measurement device to the module
output. Adjust the module’s Zero potentiometer for the
exact minimum output desired. The Zero control should
only be adjusted when the input signal is at its minimum
to produce the corresponding minimum output signal. For
example: 4 mA for a 4-20 mA output or –10 V for a ±10V
output.
4. Set the input potentiometer at its maximum, and then
adjust the module’s 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 cor-
responding maximum output signal. Example: for 4-20 mA
output signal, the Span control will provide adjustment for
the 20 mA or high end of the signal.
5. Repeat adjustments for maximum accuracy.
Output Test Function
The output test potentiometer is factory set to provide approxi-
mately 50% output. When the test button is depressed it will
drive the output side of the loop with a known good signal that
can be used as a diagnostic aid during initial start-up or trou-
bleshooting. When released, the output will return to normal.
The Test Cal. potentiometer can be used to set the test output
to the desired level. It is adjustable 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 4008 utilizes a stable 1 VDC source to excite the
potentiometer. This voltage is stabilized against the potentiom-
eter resistance value variations over the entire operating range.
The resulting potentiometer wiper voltage is amplified and
passed through an optical coupler to the output stage where it
is scaled to the desired output range.
The green LoopTracker®input LED provides a visual indication
that a signal is being sensed by the input circuitry of the mod-
ule. It also indicates the input signal strength by changing in
intensity as the process changes from minimum to maximum.
If the 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.
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,
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.

The module side label lists common ranges. Use the table
below for a complete selection of I/O ranges for your applica-
tion. See the model/serial number label for module information,
options, or if a custom range was specified.
It is generally easier to select ranges before installation.
Switch B controls the percent of potentiometer range to use.
Switch C controls the percent of input offset.
Switch D controls output offset.
Switch E is for voltage or current output selection.
For ranges that fall between the listed ranges use the next
highest setting and trim the output signal with the zero and
span potentiometers.
