Description
The APD 7393 IsoSplitter accepts a frequency 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 7393 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.

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.
Output Calibration
Input and output ranges are factory pre-configured (at 24°C ±1°C).
Front-mounted Zero and Span potentiometers are used to calibrate
the output to compensate for load and lead variations.
1. Apply power to the module and allow a minimum 30 minute
warm up time. An accurate frequency calibration source such
as a signal generator may be required for calibration.
2. Provide an input to the module equal to the minimum input
required for the application, typically 0 Hz.
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 corresponding minimum
output signal. For example: 4 mA for a 4-20 mA output or –10 V
for a ±10V output.
4. Set the frequency to the maximum required for the application. Using
an accurate measurement device for the output, 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 pro-
duce the corresponding maximum output signal. Example: for 4-20
mA output signal, set the Span control for a 20 mA output.
5. Repeat adjustments for both output channels for maximum accuracy.
Sensitivity Adjustment
This multi-turn potentiometer provides an adjustable threshold
level that the incoming signal must overcome before an output can
be produced. This is used to limit noise and minimize false input
signals that may cause erroneous readings.
Fully clockwise: (max. sensitivity), input threshold is ±25 mV.
Fully counterclockwise: (min. sensitivity), input threshold is ±2.5 volts.
Output Test Function
When a 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. potentiometer for the desired output level.
They may optionally be externally wired for remote test operation or
a manual override. See wiring diagram at right.
Operation
The APD 7393 IsoSplitter® accepts a frequency input and provides
two optically isolated DC voltage or current analog outputs that are
linearly proportional to the input.
The frequency input is capacitively coupled (to remove any DC
component at the input) to a comparator whose threshold is deter-
mined by the setting of the sensitivity control. The output from the
comparator passes through an opto-coupler to the output stage.
The green LoopTracker®input LED provides a visual indication 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 designations
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.
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
Each product is factor configured to your exact ranges as indicated
on the serial number label. Polarity must be observed for signal
wiring connections. 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 mod-
ule. Typical voltage may be 9-24 VDC at your device's terminals if it
provides power to the loop.
Input
The input range is pre-configured at the factory. No input calibration
is necessary. The frequency input is compatible with most types of
sensors that product a minimum 100 mV amplitude change and a
minimum 5 microsecond pulse width. A 15 VDC supply is available to
power the sensor if required. Always refer to the sensor manufacturer's
data sheet to determine supply voltage compatibility and proper wiring.
Sensor Load
The frequency signal input is capacitively coupled to prevent any DC
in the input. Some sensors, typically those without an internal load
resistor, require a resistive load in order to function.
The resistor value may be specified by the sensor manufacturer
as the "minimum resistive load" or calculated from the sensor
manufacturer's specified "load current range".
The 15 VDC power supply is capable of providing 25 mA. A load
current range of 3 mA to 25 mA would typically use a 5 kWto
500 Wresistor.
Module Power
Check 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.
Either polarity is acceptable for DC power, 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 position
the lower spring clips against the bottom
edge of DIN rail.
2. Push front of module upward until upper
mount snaps into place.
