Description
The APD 6393 IsoSplitter accepts an AC voltage or current
input and provides two optically isolated DC voltage or current
outputs that are linearly related to the input. The input range
and each output range are independent and can be specified as
required. This provides an economical solution when one signal
must be sent to two different devices.
Typical applications include isolation, output splitting, output
device separation and redundancy (i.e. to prevent failure of
the entire loop if one device fails), or a combination of these.
The input signal is filtered, amplified, split, and then passed
through an opto-coupler to the output stages. Full 4-way isola-
tion (input, output 1, output 2, power) make this module useful
for ground loop elimination, common mode signal rejection,
and noise pickup reduction.
I/O Sink/Source Versatility
Standard on the APD 6393 is a 15 VDC sensor excitation supply
for the input channel and 20 VDC loop excitation supplies for
each output channel. These power supplies can be selectively
wired for sinking or sourcing allowing use with any combina-
tion of powered or unpowered milliamp I/O devices.
LoopTracker
API exclusive features include three LoopTracker LEDs (green
for input, red for each 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 troubleshooting.
Output Test
An API exclusive feature includes output test buttons for each
channel to provide a fixed output (independent of the input)
when held depressed. A test button is provide for each output
channel. The output test greatly aids in saving time during
initial startup and/or troubleshooting.
The test output level for each channel is potentiometer adjust-
able from 0 to 100% of the output span.
Terminals are provided to operate the test functions remotely
for each channel. This also allows use as a remote manual
override to provide a temporary fixed output if desired.

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 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. Set the input at maximum, and 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 both output channels for maximum
accuracy.
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.
Each Test Cal. potentiometer 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. potentiom-
eter for the desired output level.
They may optionally be externally wired for remote test opera-
tion or a manual override. See wiring diagram at right.
Operation
The APD 6393 IsoSplitter®accepts an AC voltage or current
input and provides two optically isolated DC voltage or current
outputs that are linearly related to the input.
The green LoopTracker®input LED provides a visual indica-
tion that the 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.
Two red LoopTracker output LEDs provide a visual indication
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. Note that it may be difficult to
see the LEDs under bright lighting conditions.
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.
Electrical Connections
Each product is factory configured to your exact input and
output ranges as indicated on the serial number label.
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
Polarity must be observed for signal output wiring connec-
tions. If the input and/or output do not function, check wiring
and polarity.
For milliamp output 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.
