Applications
Description
The API 4400 G through API 4408 G are factory configured to
accept two to four DC voltage or current inputs and provide
an optically isolated DC voltage or current output that is pro-
portional to the sum, average and/or difference of the inputs
depending on the model.
The A, B, C, and D inputs should be the same type, and mixed
input ranges are allowable. Consult the factory when selecting
mixed input ranges.
Inputs are converted to a percentage and then the math
function is applied. Consult the factory if true voltage math
is required.
The API 4400 G series uses no transformers or choppers in the
signal path for best noise immunity and freedom from AC arti-
facts in the output. The inputs are not isolated from each other
and use the same signal common connection. The modules do
features full 3-way (input, output, power supply) isolation. A
wide bandwidth 1 millisecond response model is available for
high-speed applications.
Common ranges as well as custom ranges are possible.
Consult the factory for assistance with special ranges.
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 Functional Test Button
to provide a fixed output (independent of the input) when held
depressed. The output test level is adjustable from 0 to 100%
of output span.
The functional test button greatly aids in saving time during
initial startup and/or troubleshooting.
Installation
The API 4400 G through API 4408 G plug into an industry stan-
dard 11-pin octal socket sold separately. Sockets API 011 and
finger-safe API 011 FS allow either DIN rail or panel mounting.
The plug-in design, 3-way isolation, and robust electronics
allows the module to be quickly hot-swapped without removing
the power or I/O signals.

Calibration
Input and output ranges as specified on your order are factory
pre-configured (at 24°C ±1°C). Top-mounted, Zero and Span
potentiometers can be used to calibrate the output to compen-
sate 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 signal is at its minimum. This will produce the cor-
responding minimum output signal. For example: 4 mA for
a 4-20 mA output or –10 V for a ±10V output.
4. Next, set the input at maximum, then 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 output
signal. Example: for 4-20 mA output, 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 test button may be used to drive the device on the output
(a panel meter, chart recorder, etc.) with a known good signal
that can be used as a system diagnostic aid during initial start-
up or during troubleshooting.
When depressed it will drive the output with a known good
signal. When released, the output will return to normal.
The Test Range potentiometer is factory adjusted to approxi-
mately 50% of the output span. It can be field adjusted if
required.
Press and hold the Test button and adjust the potentiometer
for the desired output level. When released, the output will
return to normal.
Operation
The API 4400 G through API 4408 G are factory configured
series to your exact input and output requirements.
Up to four inputs can be scaled and connected to either addi-
tive or subtractive amplifier inputs according to the model
designation.
The input signal is filtered, and cancels any offset of the input
relative to the output. 50 Ωshunts are used at the input for
current-to-voltage conversion if required.
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.
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 removing
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.
Socket and Mounting
Install module in a protective panel or enclosure. Allow space
around module for air flow. Use API 011 or API 011 FS socket.
See specifications for maximum allowable socket voltages. The
socket clips to a standard 35 mm DIN rail or can be mounted to
a flat surface.
Ranges
See the model/serial number label for module information,
module power requirements, options, and I/O range informa-
tion.
API 4400 G through API 4408 G input and output ranges are
factory configured as indicated on the serial number label.
Signal Inputs
Polarity must be observed when connecting the signal input.
Terminals 4, 5, 6, 7, 8 provide the appropriate connections for
the input signal. Polarity must be observed when connecting
the signal input.
The negative (–) connection for all inputs is connected to
terminal 5.
The positive (+) connection for input A is to terminal 4.
The positive (+) connection for input B is to terminal 6.
The positive (+) connection for input C is to terminal 7.
The positive (+) connection for input D is to terminal 8.
Signal Output
Polarity must be observed for output wiring connections. If the
output does not function, check wiring and polarity.
When a current output is ordered, it provides power to the
output current loop (sourcing).
Terminals 9 (+) and 10 (–) provide the connections for the
output. Note that the output provides power to the output loop.
Module Power
Check model/serial number label for module operating voltage
to make sure it matches available power.
AC power is connected to terminals 1 and 3.
For DC powered modules (D option), polarity MUST be observed.
Positive (+) is wired to terminal 1
Negative (–) is wired to terminal 3.
