Installation and Setup
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.
API maintains a constant effort to upgrade and improve its products.
Specifications are subject to change without notice. See api-usa.com for

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

Electrical Connections
See wiring diagrams. Observe 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!
Ranges
APD 4300 I/O ranges are set at the factory and must be speci-
fied when ordering. Listed below are commonly ordered input
and output ranges. Consult factory for other available ranges or
special ranges. See the model/serial number label for module
information, options, and I/O range information.

Input
Polarity must be observed when connecting the signal input.
For a transmitter with a current output, determine if it provides
power to the current loop or if it must be powered by the APD mod-
ule. Use a multi-meter to check for voltage at the transmitter output
terminals. Typical voltage may be in the range of 9 to 24 VDC. In
this case, wire the device to terminals 9 and 11.
Type of Input Device
– Terminal + Terminal
Sensor or transmitter w. voltage output.
Transmitter with a mA (current) output
that provides power to the current
loop. Typically a 3 or 4-wire device.
Transmitter with mA (current) output that
is unpowered. Typically a 2-wire device.
APD module provides loop power.
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 mod-
ule. Use a multi-meter to check for voltage at the input terminals.
Typical voltage may be in the range of 9 to 24 VDC. In this case,
wire the device to terminals 2 and 4.
Device Connected to Output

Measuring or recording device accepts
a voltage input.
Measuring/recording device accepts a
mA (current) input and the input is
unpowered or passive. APD module

Module Power Terminals
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 con-
sistency with similar API products, positive (+) can be wired to
terminal 13 and negative (–) can be wired to terminal 16.
The power supplies are fuse protected and the unit may be
returned to API for fuse replacement.
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. Allow 1" (25
mm) above and below housing vents for air circulation.
1. Tilt front of module downward and position against DIN rail.
2. Clip lower mount to bottom edge of DIN rail.
3. Push front of module upward until upper mount snaps into
place.
Removal
1. Push up on the bottom back of the 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 as specified on your order are factory
pre-configured (at 24°C ±1°C). Front-mounted, Zero and Span
potentiometers can be used to calibrate the output to compensate
for load and lead variations.
1. Apply power to the module and allow a minimum 20 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
±200 mV
signal is at its minimum. This will produce the corresponding
±500 mV
minimum output signal. For example: 4 mA for a 4-20 mA
±1 V
output or –10 V for a ±10V output.
±2 V
4. Next, set the input at maximum, then adjust the Span pot for
±5 V
the exact maximum output desired. The Span control should
±10 V
only be adjusted when the input signal is at its maximum.
This will produce the corresponding maximum output signal.
0-100 mA
Example: for 4-20 mA output, the Span control will provide
0-200 mA
adjustment for the 20 mA or high end of the signal.
0-500 mA
5. Repeat adjustments for maximum accuracy.
Output Test Function
±5 V
The test button may be used to drive the device on the output (a
±10 V
panel meter, chart recorder, etc.) with a known good signal that
can be used as a system diagnostic aid during initial start-up or
4-20 mA
during troubleshooting.
When depressed it will drive the output with a known good signal.
When released, the output will return to normal.
You can also enable the test function by connecting an external
switch or button to terminals 5 and 6. This can be used as a
remotely operated manual override to set the output at a fixed
value regardless of the input signal.
The Test Cal. potentiometer can be used to set the test output to
the desired level. It is factory set to provide approximately 50%
output. It is adjustable from 0 to 100% of the output span. Press
9 (–)
11
(+)
and hold the Test button and adjust the Test Cal. potentiometer
for the desired output level. When released, the output will return
9 (–)
11
(+)
to normal.
Operation
The APD 4300 is factory configured to your exact input and output
10
11 (–)
requirements. The input is filtered, either amplified or attenuated
(+15 VDC)
as required, then passed through to the output stage.
The green LoopTracker
that a signal is being sensed by the input circuitry of the module.
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
3 (–)
4
(+)
input and the corresponding output change from minimum to
maximum.
For current outputs, the red LED will only light if the output loop
3 (–)

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
