Introduction
This is the users’ manual for Moore Industries’
SDY PC-Programmable Signal Isolator/Converter.
It contains all of the information that is needed
to congure, install, operate, maintain, and
troubleshoot the SDY. If you require additional
assistance, call one of our STAR Centers (for
Service, Technical Assistance, and Repair) to talk
with a technician or engineer.
The following guidelines are used in this manual:
WARNING - Hazardous procedure or condition that
could injure the operator.
Caution - Hazardous procedure or condition that
could damage or destroy the unit.
Note - Information that is helpful for a procedure,
condition, or operation of the unit.
The SDY
The SDY is a versatile, 2-wire (loop-powered),
PC-Programmable Signal Isolator/Converter that
accepts current or voltage input and provides an
isolated, proportional 4-20mA output. See Figure 1
for a list of accommodated input types.
Typical uses for the SDY include:
• Isolating Signals to stop erratic process
measurements caused by ground loops
• Converting Signals so eld instruments can
interface directly with indicators, recorders,
DCS’s, PLC’s, and PC-based SCADA systems
• Diverting Signals so the output from one
transmitter can be sent to two separate locations
• Protecting Equipment and Signals by eliminating
common electrical paths
• Boosting Signals to enable more instruments to
be added to an overburdened loop
• Solving the “Bucking Power Supplies” problem
that occurs when a 4-wire transmitter and a
DCS both try to power the same process loop
Figure 1. Compact, yet powerful, the SDY transmitter features programmable inputs and a trimmable output to boost accuracy.

Conguration
Conguring the SDY consists of:
1. Checking to verify that the unit ordered is in fact
the one received and that it has been correctly
calibrated by the factory according to the order.
2. Installing the SDY Conguration Software by
following the directions on the label.
3. Connecting the SDY to a PC and test setup,
running the SDY PC Conguration Program to
check for correct unit tagging, input type and
range settings, and output zero/span trim.
Prior to shipment, our team of skilled technicians
subjects every SDY to rigorous testing. Every
product Moore Industries manufactures, sells, and
services is guaranteed to meet the strict quality
standards that our company demands.
Even if a unit has been congured to your
specications by the factory (factory calibration),
it is a good idea to perform a bench check. In
addition to providing a safe means of uncovering
any unit damage that may have occurred during
shipping, the procedures aord the user the
opportunity of becoming familiar with SDY operation
in a testing environment that is separate from the
intended process or application.
Installing the
Conguration Software
Refer to Table 1 for the equipment needed.
1. Insert the Moore Industries Interface
Solution PC Conguration Software CD
into the CD drive of the PC. Access the
CD and open the SDY SIY TDY TRX
TRY 64 bit PC Conguration software
folder.
2. Double-click the installation program
located in the folder. Follow the
prompts to correctly install the program.
Once the Conguration Program is installed on the
PC, the SDY can be connected to equipment to
simulate input and monitor output. You can then
change the transmitter’s operating parameter
CAUTION:
Any time a connected SDY is “programmed”
by downloading a Conguration File into memory,
ALL of the conguration parameters resident
in the transmitter memory at the time of the
download are OVERWRITTEN. This includes
things like: tag name, calibration date, trim values,
etc.
Note:
The procedures in this section should be carried
out in an environment considered appropriate for
the general testing of electronic equipment, rather
than in the eld. Use a technician’s bench or
similar, lab-type environment.

Bench Check Setup
Figure 2 shows a SDY hooked up to the equipment
needed to perform the unit conguration, bench
check, and output trim. See Table 1 for a list of
the necessary equipment. Connect your SDY
as shown in the gure and allow approximately 5
minutes for the setup to stabilize.
Figure 2. Setting up the SDY for Conguration/Bench Check
It is possible to run the SDY Conguration program
without actually connecting a unit to the PC, but you
will be unable to set a custom linearization table.
This makes it easy to devise and download a single
conguration to several SDY. To do this, save
the Conguration File to disk, connect the units in
succession, and download the same le to each.

Using the SDY PC Conguration
Program
Once the software has been installed on your hard
disk:
1. Run the PC Conguration Program.
2. Set the values as appropriate for your
SDY application in the various elds of the
Conguration Screen shown in Figure 3.
Note:
If you are building a Conguration File
without a SDY connected, the “SDY Status”
section of the screen will be blank, and the
“Communication” indicator will show steady
ON (as opposed to blinking).
8 The Interface Solution Experts
During setup, the SDY tests the availability
of COM Ports 1 through 4 in your system.
The rst available COM port is designated
for SDY communications and is noted
on the Conguration Screen. Your SDY
communications cable must be connected
to this port.
To connect the SDY to a port other than
the default described above, disconnect
the transmitter, then change the default
selection with the pull down menu. Next
reconnect the SDY communications cable.
3. When the Conguration File shown on the
screen has been modied for your intended
application, click the “Stop” button to stop
measurement.
SDY

download the parameters on the PC into the
nonvolatile memory of the connected SDY.
Status of the downloading is shown in the
upper left corner of the screen. When
completed, the program beeps.
Note:
Changing the settings on the Conguration
Screen does not change SDY parameters
until the Conguration File is downloaded to
SDY memory as described in Step 3 above.
Any time the SDY settings are changed, the
conguration date will change to reect the
date the new settings were entered.
Saving the SDY Conguration
File to Disk
This is an optional procedure. You do not have
to save the le to disk in order to download the
le into SDY memory. Use this procedure to save
information on the conguration of your SDY for
downloading into other SDY transmitters, or for
record-keeping purposes, etc.
To save the SDY conguration les to disk:
1. Click on the “File” button. This brings up an
Explorer-like window on the left area of the
screen.
2. Enter the le name that you wish to save in
the “Selected File Name” box.
Printing Saved Congurations
1. Click on the “File” button. This brings up an
Explorer-like window on the left area of the
screen.
Note:
File names must follow the DOS convention.

Loading a Conguration File From
a Connected SDY
To edit or view a Conguration File in the nonvolatile
memory of a connected unit, you can use the “Get
Setup” function of the Conguration program.
Note:
Whenever a unit is correctly connected to your
PC, the “SDY Status” section of the Conguration
Screen will show the conguration data already
stored in unit memory.
To load a conguration le from a SDY, connect a
powered SDY and click “Get Setup”.
The editable elds of the SDY Conguration Screen
will change to match the data shown in the “Status”
portion of the screen.
Setting Output Damping
To lessen the impact of your sensor’s step increases
and decreases, you may want to set the damping
time, which will cause the SDY to average out
uctuations over the set amount of time.
Setting the damping time is simple; simply click
on the damping value bar under the “Output”
portion of the screen (in the bottom-right corner),
or click on the box to the right of the
“Damping(sec)” area and type in a number
between 0 and 20.032. This number is the number
of seconds that the sensor’s value will be
averaged over.
Trimming SDY Output
The SDY has a function that allows precise control
over its output. Note that to activate this function, a
unit must be connected in the setup to a current
meter, as shown in Figure 2.
To trim SDY output:
1. Set all unit parameters on the SDY
Conguration Screen as required for your
intended application. Click “Stop” to stop
measurement.
2. Click “Out Trim”.
3. Select and move the “Output Zero” or the
“Output Full” slide bar to adjust the SDY output.
Monitor the output with a calibrated current
meter or with a voltmeter measuring the drop
across a precision, 250 Ohm resistor
(see Figure 2).
4. When both zero and full scale have been
adjusted to satisfaction, press “Quit Trim”, then
“Prog” to program the SDY with the new trim
values.
Note:
Changing the settings shown on the screen in
“Trim” mode DOES NOT CHANGE THE UNIT’S
OPERATING PARAMETERS, it only updates
the screen. The settings are saved to nonvolatile
memory by using the “Prog” function.
The “SDY Status” area of the
Conguration Screen will reect the new
output settings being downloaded into unit
memory.

Scaling the SDY Output
To scale the transmitter’s output, use the mouse to
move the slider bars in the “Output” section of the
Main Conguration screen. “Zero Scale Output”
eects the zero output, and “Full Scale Output”
eects full scale output.
Note:
The SDY Output Scaling function will not operate
unless a SDY is connected in the calibration setup
shown in Figure 2.
Setting the Display
The SDY has numerous settings for its display, all
of which are controlled using the “Input Range and
Setup Options” box. You can set the customizable
display to display the input, output, or toggle
between the two every two seconds. The display
will even scale to display any type of engineering
units you desire.
Input, Output, and Toggle
The pull-down menu shown below is used to adjust
what the SDY displays. There are three settings:
“Input”, which causes the SDY to display the input
it is receiving, “Output”, which causes the SDY
to display the 4-20mA output it is emitting, and
“Toggle”, which causes the SDY to switch between
displaying Input to Output every two seconds. To
switch between these, simply click on the pull-down
menu, select the appropriate function, and program
the transmitter by clicking the “Prog” button.
Display Zero & Display Full
The display zero and display full show what values
will actually be displayed. If the pull-down menu in
Figure 4 and the radio button on Figure 5 both have
“Input” selected, then Display Zero will match Input
Zero and Display Full will match Input Full.
Figure 5. Use the Display radio button to switch from standard
input display to a scaleable display of any engineering unit type.
Scaling the Display
The SDY can scale its display. This feature is useful when you need to limit, expand, or manipulate
the numbers the SDY displays. Doing this also
gives you the option of changing the engineering
units being displayed to any engineering unit type.
Scaling the input display is a simple procedure.
First, click “Scale” on the radio button in Figure 5.
Note:
If you have the pull-down menu in Figure 4 set
to “Output”, the Display radio button will not be
available.
You can then enter values into the “Display Zero”,
“Display Full”, and “Display EGU” boxes. When
you have entered the appropriate values, program
the SDY with the new information by clicking the
“Prog” button.
Figure 4. The pull-down menu lets you select what the SDY
displays.

Trimming the Input
Use this feature of the SDY to enhance the
accuracy of the transmitter by precisely matching its
actual input reading to its scaling of the either one
or two input points. Trim the input by following the
directions below:
1. Connect the transmitter to your PC using the
setup shown in Figure 2.
2. Click the radio button labeled “Input Trim On”.
3. Click “Start”, then “InpTrim”.
4. Select whether you will trim two points (upper
and lower) or just one point by clicking on the
appropriate radio button in the “Trim Pnts”
section.
5. In the “Trim Lower” and “Trim Upper” boxes,
type in the sensor’s value that you are
trimming.
6. Attach an input source to the transmitter.
Using a calibrated multimeter to determine
the current, set the input source to match the
“Trim Lower” value you have chosen. Click
“Trim Lower” and wait for it to capture the
value.
7. Using a calibrated multimeter to determine the
current, set the input source value to match
the “Trim Upper” value you have chosen.
Click “Trim Upper” and wait for it to capture
the value.
8. Click on the button labelled “QuiInTrim”, then
the “Stop” button, and nally the “Prog” button
to send the trim values to the transmitter.
Creating a Custom Linearization Table
The SDY supports user-dened linearization of
both voltage and current inputs. Up to 85 input/
output points can be dened, and the user can
also specify the format and engineering units of the
output (viewable with the Conguration Program).
This section explains how to create a Custom
Linearization Table for downloading into SDY
memory.
The instructions assume that the Conguration
Program has been loaded successfully. Moore
Industries also suggests saving the initial settings
resident in the transmitter before making any
changes.
To create a Custom Linearization Table:
1. Attach the equipment listed in Table 1
as shown in Figure 2 and start the PC
Conguration Program.
Note:
It IS NECESSARY to connect a unit to the PC in
order to create a Custom Linearization Table.
2. Use the pull-down menu to set “Linearization
ON”.
Figure 7. Linearization must be set to ON to create a custom
table
Figure 6. Trim Capture Box
12 The Interface Solution Experts
3. Click on the “CustTable” (Customize
Linearization Table) button. This causes the
Conguration Program to change its upper-
right corner area to accommodate the table.
4. Use the table elds to set values for input
and output from the transmitter’s intended
application.
Use the Up, Down, Left, and Right arrow
keys on the PC keyboard to move the cursor
among the cells in the table.
SDY
PC-Programmable Signal
Isolator/Converter with Display
5. Use the “Restore” button to revert to the table
stored in the SDY’s memory.
Caution:
Restoring the conguration le erases any values
in the table, overwriting them with whatever is
stored in the most recent le.
6. Use the “EGU” eld to set the Engineering
units of the readout from the main window
when connected to the Conguration
Program.
7. Set the “Output Format” eld to the desired
resolution using the pull-down menu.
8. Enter the number of points to use to constitute
the Linearization Table in the “Points” eld.
The Rules for Custom Linearization:
• The dierence between any consecutive
values in the table (in either column)
must be less than 50% of the entire
congured range.
• One “Output EGU” value per “Input mV”
value only.
• It is not necessary to use all 85
available points, but the rst and last
points in the curve always default to the
0% and 100% input scale (input range).
• If you decide not to use all 85 points,
you must change the number of points
in the “Points” eld to the number you
wish to use.
9. When the table is complete, click on the
“QuitTabl” button and answer “Yes” to the
following dialog (or something similar).
Figure 8. Save File Dialog Box
10. Click on the “Prog” (Program) button to
download the linearization table settings into
the transmitter memory.
CAUTION:
Any time a connected SDY is “programmed”
by downloading a Conguration File into memory,
ALL of the conguration parameters resident
in the transmitter memory at the time of the
download are OVERWRITTEN.
This includes things like: tag name, calibration
date, trim values, etc.
Once a transmitter’s memory is “erased”
in this fashion, the old operating parameters
are unrecoverable, and will have to be
regenerated from scratch if needed again.
Note:
Moore Industries suggests lling in the EGU
(Engineering Units), then the number of points, and
nally the values in the table.

mounting in one of our durable enclosures, such
as the explosion-proof BH or NEMA 4X-compliant
D-BOX.
Figure 11 shows the dimensions of the HP housing.
The dimensions of the SDY enclosures are shown
in Figures 9 and 10.
Mounting and Connections
Moore Industries suggests installing the SDY by
rst mounting the unit in its intended application,
then making the electrical connections to input,
output, and power.
Before any installation, make sure that the unit has
been bench checked to ensure that it is congured
and calibrated for its intended application.
Mounting the SDY
To mount the SDY, use 4.5mm (0.18 in) screws to
connect the SDY and mounting plate to a connec-
tion head or other housing.
Electrical Connections for the SDY
Figure 12 shows the hookups for the SDY. Feed
the sensor wiring up through the center thru-hole
(and typically, out a side port of the connection
head).
Recommended Ground
Wiring Practices
Moore Industries recommends the following ground
wiring practices:
• Any Moore Industries product in a metal case or
housing should be grounded.
• The protective earth conductor must be
connected to a system safety earth ground
before making other connections.
• All input signals to, and output signals from,
Moore Industries’ products should be wired
using a shielded, twisted pair wiring technique.
Shields should be connected to an earth or
safety ground.
• For the best shielding, the shield should be
run all the way from the signal source to the
receiving device. (see Note below)
• The maximum length of unshielded input and
output signal wiring should be 2 inches.
Note:
Some of Moore Industries’ instruments can be
classied as receivers (IPT 2, IPX 2, etc.) and some
can be classied as transmitters (TRX, TRY, etc.)
while some are both a receiver and a transmitter
(SPA 2, HIM, etc). Hence, your shield ground
connections should be appropriate for the type
of signal line being shielded. The shield should
be grounded at the receiver and not at the signal
source.
CE Conformity
Installation of any Moore Industries’ products that
carry the CE marking must adhere to the guidelines
in the Recommended Ground Wiring Practices
section in order to meet the EN 61326 requirements
set forth in the applicable EMC directive.

Operation
Once programmed, calibrated, installed, and
supplied with the correct power, SDY transmitters
begin to operate. Depending upon environmental
conditions, they can be expected to continue to
operate unattended for extended periods of time.
Maintenance
Moore Industries suggests you perform a quick
check for terminal tightness and general unit
condition every 6-8 months. Always adhere to any
site requirements for programmed maintenance.
Troubleshooting
If a transmitter’s performance begins to deteriorate
noticeably and a physical check of the installation
uncovers no adverse conditions or damage, remove
the unit from service and perform the calibration
procedures listed earlier in this manual. Check in
particular the Trim Output procedure.
