Description
The APD 4930 IsoSplitter accepts a DC 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.
Independent Outputs
Each output channel is factory ranged to your specifications
and provides an optically isolated DC voltage or current output
that is linearly related to the input. Sourcing mA outputs are
standard. Sinking milliamp or high voltage outputs are optional.
Isolation
The full 4-way (input, output 1, output 2, power) isolation
makes this module useful for ground loop elimination, common
mode signal rejection or noise pickup reduction.
LoopTracker
API exclusive features include two LoopTracker LEDs (one for
each output channel) that vary in intensity with changes in the
process 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.

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 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.
Ranges
See the model/serial number label for information, options, and
I/O range information. The voltage and/or milliamp I/O ranges
are factory set for each channel to your exact specifications.
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!
Signal Input Terminals
Polarity must be observed when connecting the signal input.
Terminal 3 provides 20 VDC to power a passive mA transmitter
if required.
The APD 4930 splits and converts a single input signal into two
outputs. See the wiring diagrams at right.
Signal Output Terminals
Polarity must be observed when connecting the signal outputs.
See the module label for the voltage or milliamp output range
for each channel. The standard milliamp output is sourcing. It
provides 20 VDC power to your device.
Optional sinking mA output(s) will be indicated on the module
label as EXT1 for channel 1, EXT2 for channel 2, or EXT3 for
both channel 1 and channel 2.
If the output does not function, check wiring and polarity for
both input and outputs. See note about terminating an unused
mA output channel.
Module Power Terminals
Check model/serial number label for module operating voltage
to make sure it matches available power. The power supply
is fuse protected and the unit may be returned to API for fuse
replacement.
When using DC power, either polarity is acceptable, but for
consistency with similar API products, positive (+) can be wired
to terminal 13 and negative (–) can be wired to terminal 16.
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 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 mod-
ule 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 pre-configured at the factory (at
24°C ±1°C) as specified on your order. Front-mounted, Zero
and Span potentiometers for each channel 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 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.
Operation
The APD 4930 is factory configured to your exact input and
output requirements. The voltage or milliamp input is filtered,
either amplified or attenuated as required, then passed through
an optical coupler to the output stage.
A red LoopTracker output LED provides a visual indication that
the output signal is functioning for each channel. 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.
