SIX
Introduction
Moore Industries’ Signal Isolator/Converter (SIX) is a
DIN-style, loop-powered device, used to provide
complete isolation of instrumentation input and
output. This helps eliminate faulty readings in
measurement and control equipment caused by
ground loops, electrical interference, or motor noise.
This manual provides a brief description of the SIX, a
list of performance and functional specifications, a
calibration procedure, operations notes, and trouble-
shooting information.
Notes and Cautions, where they appear in text or
illustrations, are provided to assist the user in
avoiding operational inconveniences (Notes), or
practices that otherwise might result in damage to
the unit (Cautions).
Description
The SIX is loop-powered. When connected in a 12-
42 Vdc loop, it converts a standard process current
or voltage signal to a proportional, isolated 4-20 or
10-50 mA output; breaking the galvanic path be-
tween a transmitted signal source and its receiving
device.
The unit is packaged in a compact, DIN-style hous-
ing that snaps easily on to G-rail mounting hardware
(DIN EN50035). This makes it ideal for use in high
density installations.
Controls
The SIX has Zero and Span potentiometers located
on the front panel of the unit. On older units these
were labeled:
for Zero, and
for Span.
On newer the words “ZERO” and “SPAN” may be
used to identify the potentiometers.
Table 1 consists of the SIX performance and func-
tional specifications.
Options
Units may be ordered with RFI-filtered terminals and
case assembly (RF Option). RF-equipped units
providesless than ±0.1% of span error when tested
at 10V/m@ 20-1000MHz.
Contact your Sales Representative or Moore Indus-
tries for more information on available SIX options
and compatible devices.
Serial Number. A complete history of every unit
sold and serviced by Moore Industries is kept at the
factory. This data is keyed to each unit’s serial
number. If service data is required on an SIX,
providing the factory with the unit serial number will
allow our highly skilled technicians to better assist
you.
The SIX serial number is located on a label affixed to
the side panel of the unit.
Model Number. Moore Industries' model numbers
identify the type of instrument, functional character-
istics, operating parameters, any options ordered,
and housing type. If all accompanying documenta-
tion for a unit is missing, the model number may be
used to obtain technical information.
The model number for the SIX is located on the same
label as its serial number.
The example following Table 1 is provided to assist in
deciphering the fields of the SIX model number.
Calibration
Prior to unit shipment, each SIX is calibrated and
tested according to Moore Industries’ strict quality
control guidelines. It is recommended, however, that
a bench check of potentiometer settings and output
levels be performed before placing the SIX into
service.

Figure 1. SIX Calibration Setup
Note that there are no internal adjustments or settings
to effect on the SIX. Disassembly of any kind is not
recommended.
After applying power, allow approximately five min-
utes for stabilization/warm-up.
Calibration Procedures
There are two options for monitoring the output of the
SIX shown in the figures; either a dc milliammeter or
a dc voltmeter with load resistor may be used to
monitor and set output levels.
1. With the calibration setup complete, adjust both
potentiometers 15 turns counterclockwise, then
7.5 turns clockwise (mid-scale).
2. Simulate zero percent input.
3. Adjust zero potentiometer until milliammeter
reads 4 mA for 4-20 mA units, 10 mA for
10-50 mA units, or until voltmeter reads 1 volt.
CAUTION
To avoid damaging the housings, use a
screwdriver with a head not wider than
2.54 mm (0.1 inch) to adjust the zero and
span potentiometers.
4. Set input to 100 percent.
5. Adjust span potentiometer until milliammeter
reads 20 mA for 4-20 mA units, 50 mA for
10-50 mA units, or until voltmeter reads 5 volts.
6. Repeat steps 2 through 5 until zero and 100
percent readings are stable, ±0.1%.

in the illustration, and apply the power according specification (refer to the specifications table and the
model number of your unit).

SIX
Installation
In this manual, the installation of the SIX is divided
into two phases: physically mounting the unit, and
making the electrical connections. It is recom-
mended that the unit(s) be mounted before making
any connections.
Mounting
When mounting the SIX, make every effort to install it
in an area that is relatively free of dust, moisture, and
corrosive materials.
Figure 2 shows the mounting dimensions for the SIX.
To mount the unit on a DIN-style G-rail, insert the
metal clip on the unit’s back panel under the top lip of
the rail. Pivoting on the clip, press down firmly until
the SIX snaps into place.
If it becomes necessary to remove the unit, grasp the
bottom of its front panel and lift upward.
NOTE
The SIX has no case ground connection.
If possible, avoid mounting the unit in any
electrical field. Secure the case to a
good conductor at zero potential.

Electrical Connections
The SIX has four terminals on its front panel. They
are labeled “+IN” and “–IN” for connection of the
signal input, and “+PS” and “–PS” for connection of
the unit’s output.
Figure 3 illustrates the connection of the SIX in a
generic application.
Figure 4 shows the unit connected in another typical
operational scenario.
To complete these connections, use a small, slotted
screwdriver to loosen the SIX terminal screws, and
slip the appropriate stripped wire end into the terminal
hole. Tighten the terminal screw.
Both the input and output may be grounded. The SIX
input and output are isolated with no dc connection
between them.

SIX
Operation
Once mounted and connected according to the
instructions, the SIX operates unattended. After the
initial calibration of the Zero and Span potentio-
meters, no further adjustment is required.
Maintenance
A check of terminal connections is recommended
every six months. Ensure that all terminal screws are
tight and free of corrosion. Check that adequate
ventilation exists, or that heat sinking materials are
used in mounting.
Troubleshooting
If the SIX is found to be performing below specifica-
tion, complete the following checklist:
1. Make sure all connections are clean and tight.
2. Verify the accuracy and calibration of bench
instruments used to take measurements.
3. Ensure that signal and power levels in the
instrumentation loop have not changed since the
unit was installed. Make sure that power is
within specified limits (refer to table 1).
If problems persist, note the serial and model num-
bers of the offending unit, and contact Moore Indus-
tries’ Customer Service Department. Instructions for
return of Moore Industries equipment are on the back
cover of this manual.

To return equipment to Moore Industries for repair, follow these four steps:
1. Call Moore Industries and request a Returned Material Authorization (RMA) number.
Warranty Repair –
If you are unsure if your unit is still under warranty, we can use the unit’s serial number to verify the warranty status for you
over the phone. Be sure to include the RMA number on all documentation.
Non-Warranty Repair –
If your unit is out of warranty, be prepared to give us a Purchase Order number when you call. In most cases, we will be
able to quote you the repair costs at that time. The repair price you are quoted will be a “Not To Exceed” price, which means
that the actual repair costs may be less than the quote. Be sure to include the RMA number on all documentation.
2. Provide us with the following documentation:
a) A note listing the symptoms that indicate the unit needs repair
b) Complete shipping information for return of the equipment after repair
c) The name and phone number of the person to contact if questions arise at the factory
3. Use sufficient packing material and carefully pack the equipment in a sturdy shipping container.
4. Ship the equipment to the Moore Industries location nearest you.
The returned equipment will be inspected and tested at the factory. A Moore Industries representative will contact the person
designated on your documentation if more information is needed. The repaired equipment, or its replacement, will be returned to
you in accordance with the shipping instructions furnished in your documentation.
