Instructions
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.
API maintains a constant effort to upgrade and improve its products.
Specifications are subject to change without notice. See api-usa.com for
latest product information. Consult factory for your specific requirements.
WARNING: This product can expose you to chemicals includ-
ing nickel, which are known to the State of California to cause
cancer or birth defects or other reproductive harm. For more
information go to www.P65Warnings.ca.gov
Electrical Connections
See wiring diagrams at right. Observe polarity. If the output
does not function, check wiring and 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!
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
terminals if it provides power to the loop. See note about
terminating an unused mA output channel.

Inputs, DC
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
terminals if it provides power to the loop.
DC Input Channel 1
Sensor or transmitter with voltage output. 17 (–)
Transmitter with a mA output that pow-
ers the current loop. Typically a 3 or
4-wire device.
Transmitter with an unpowered mA
output. Typically a 2-wire device. APD
module provides loop power.
DC Input Channel 2
Sensor or transmitter with voltage output. 21 (–)
Transmitter with a mA output that pow-
ers the current loop. Typically a 3 or
4-wire device.
Transmitter with an unpowered mA
output. Typically a 2-wire device. APD
module provides loop power.
Module Power Terminals
Check model/serial number 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.

Mounting to a DIN Rail
Install module vertically on a 35 mm DIN rail in a protective
enclosure away from heat sources. Do not block air flow. Allow
1" (25 mm) above and below housing vents for air circulation.
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.
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-
Terminal Terminal
responding minimum output signal. For example: 4 mA for
3 (–)
4
(+)
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
3 (–)
4
(+20 V)
only be adjusted when the input signal is at its maximum.
This will produce the corresponding maximum output

3

signal. Example: for 4-20 mA output, the Span control will
provide adjustment for the 20 mA or high end of the signal.

accuracy.
Output Test Function

(+20 V)
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-
Terminal Terminal
tion or a manual override. See wiring diagram at right.

Operation
The APD 2000 accepts two independent DC voltage or current

inputs and provides two independent and optically isolated DC
voltage or current outputs that are linearly related to each input.

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
23 (–) 22
(+15 V)
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.

To maintain full isolation avoid combining power supplies
in common with inputs, outputs, or unit power.
* To avoid damage to the module, do not leave any unused
