SCADA 3000 User’s Manual
I. Installation
This chapter provides information necessary to install the Universal Input Module. Correctly
installing the unit will ensure proper functioning and maximum service life. Please read the
entire chapter before attempting installation.
OPERATING ENVIRONMENT
The Universal Input Module should be mounted and operated in a clean, dry and safe environment. Do not mount the unit where it will be subject to shock and vibration. Do not mount
the unit where it will be subject to dirt, dust or moisture. Ideally the unit would be mounted in a
steel or a fiberglass NEMA-4 enclosure. Do not mount the unit or the expansion modules close
to motor starters, contactors or relays that switch inductive loads. These devices generate large
electromagnetic fields that can cause the Universal Input Module to malfunction. Where this is
unavoidable, mount the module(s) and main unit in a separate, grounded, steel enclosure. This
will shield them from harmful electrical interference.
The temperature range the Universal Input Module can operate in is 32°F to 158°F (0°C to
70°C). If you require Universal Input Module to operate in a below freezing environment, you
must take safe and practical measures to keep the module’s temperature above 32°F or it will not
operate reliably.
CAUTION: The Universal Input Module is a sensitive electronic device. Personnel and work area should be grounded before handling this device. Do not install a
SCADA 3000 system near any strong electrostatic, electromagnetic, magnetic or
radioactive fields. Do not expose it to fumes or corrosive vapors.
MOUNTING THE UNIVERSAL INPUT MODULE
When you receive the Universal Input Module, carefully remove it from the box. On the top
and bottom of the enclosure are mounting holes to attach the unit to either a panel or wall. The
mounting surface should be sturdy enough to support 2 lbs. The unit should be mounted using
four #10-32 bolts where appropriate, or four #10 tapping screws. (The screw kit for the Universal Input Module includes 4 #10-32 screws, 4 #10-32 nuts, 4 #10 lockwashers, and 2 #6-32
screws, 2 #6-32 nuts, and 2 #6 lockwashers. The #6 hardware is for the power supply, if necessary.) When mounting the unit to a wall make sure the mounting screws fully engage a solid
member (for example, a stud) of the support structure. Mount the Universal Input Module in an
upright position so that you can easily connect wires to the terminal strips. The dimensions of
the full enclosure are: 6.1" x 6.3" x 1.2". See Figure 1.

POWER SUPPLY AND GROUNDING
The Univseral Input Module operates on 10-15VDC. Typically the module is powered from the
AUX PWR terminals on the SCADA 3000 main unit. This is preferred because the AUX PWR
from the main unit is battery-backed in the event of a power failure, when a battery is connected
to the main unit. Alternately, you may connect the module to any 10-15VDC power source.
The module requires 1.5 Watts of power.

SCADA 3000 User’s Manual
It is extremely important that the EG pin be connected to a good earth ground. This will
prevent communication errors due to differences in ground potential between modules in
addition to possible damage due to voltage transients and surges.
The two LED lights in the center of the module, marked Power and Pulse indicate that the
module is receiving power and operating properly. The Pulse LED will blink at a regular rate,
like a heartbeat, once it establishes communication with the main unit.
The module generates a 24V power supply for use with 4-20mA transducers. Module power
consumption will vary depending on how much power is being drawn from this supply. For
estimation purposes add 38mA to the power consumption specification for every 4-20mA loop
powered by the module. For example, since the module consumes 100mA by itself, if two 420mA transducers are connected to the 24V supply, then the estimated total power consumption
should be 176mA.
COMMUNICATIONS WIRING
The Universal Input Module communicates with the SCADA 3000 using a high-speed serial
communications bus. This 4-wire bus is used to connect up to 15 modules to the main unit to
provide additional inputs and/or outputs. Perform all wiring with power to the main unit and
modules turned off.
Modules may be located a maximum of 2000' away from the main unit and should be connected
in a daisy-chain fashion from one module to the next. Each module connects to the next via a 4wire communications cable connected to the terminals labeled A,B, Z & Y. The cable must be4-Conductor Twisted Pair (shielded or unshielded) with a nominal impedance of 120Ω (for
example, Belden #8132 or 9842 cable). Use one pair for A & B and the other pair for Z & Y. The
proper wiring from the main unit to the modules, and from module to module, is shown in
Figure 3:

Bus Termination
Located on each module is a jumper labeled BUS TERM. This jumper is used to terminate the
4-wire communications bus.

Termination is required at the extreme ends of the communications network to minimize signal
reflections that would otherwise cause data communication errors. To activate the Bus Termination, move the jumper to the IN position. Note that this should only be activated if the module
is at the very end of the network. All other modules in between should have the termination set
to the OUT position. As a result, only 1 module should ever have the termination activated.
The diagram below illustrates proper termination of the communications bus.

Sensor/Transducer Wiring
The Universal Input Module is compatible with a wide variety of electrical signal sources
including contacts, 10K thermistors, analog voltage outputs and 4-20ma current sources. Each
UIM-9
SCADA 3000 User’s Manual
type of signal requires the configuration jumpers, located behind the terminal strip, to be installed in the proper position for each type of signal. Follow the instructions below to properly
wire and configure the inputs for each type of electrical signal. Note: Needlenose pliers will be
required to move the jumpers.
Warning: The inputs are designed to work with low voltage signals from 0-5V. DO
NOT connect differential voltages greater than 5V to the inputs. DO NOT connect
120VAC to the inputs. In the 4-20mA jumper position and when no jumper is
installed, the inputs are differential and will work with signals that are +/-12V away
from power supply ground. This allows the use of multiple 4-20mA circuits on one
loop. See circuit schematics for more information.
General Wiring Considerations
Most dry contact sensors can be connected to the module using inexpensive 2-conductor cable as
small as #24 AWG. For thermistor, 0-5V and 4-20mA sensors, use the wire chart below as a
reference for selecting the appropriate wire gauge. Note that if the sensor is located far from the
module or if you are running cable in an electrically noisy environment, you should seriously
consider using twisted pair shielded cable. This will shield the signal from electrical interference
thereby preventing false readings and/or damage to the module.

Normally Open/Normally Closed Dry Contacts
Dry contact sources consist of relays or switches that are isolated and have no external voltage
applied. These devices can be connected directly to the input terminals without regard for
polarity. Choose an input and connect the wires to the corresponding screw terminals for that

4-20mA Current Loop Transducers
The Universal Input Module is compatible with transducers that produce an analog output
current of 4 to 20mA. You can program High and Low table values from the SCADA 3000
Software to scale the signal to the appropriate values.
Analog 4-20mA output devices typically require a 24VDC power supply to operate. The Universal Input Module has an internal 24VDC power supply available for this purpose. The
24VDC power supply has enough capacity to power up to eight 4-20mA devices. Follow the
wiring diagrams below for connecting a 4-20mA device. The configuration jumper should be

HOW THE UNIVERSAL INPUT MODULE WORKS
The Universal Input Module provides eight inputs that can be configured for use with a variety
of sensors. Each input has a configuration jumper that conditions the signal appropriately based
on the attached sensor. The module continuously reads the signal at each input and communicates the value back to the SCADA 3000 via the 4-wire communications bus. The SCADA 3000
will allow you to set customized tables to scale the input accordingly. The value of each input
can be used in the ladder program or C-program to perform control functions. You may even
choose just to monitor or datalog an input and activate alarms based on high and low set-points.
The SCADA 3000 User’s Manual provides information on how to take advantage of all the
possibilities. Listed below are some of the possible applications for the Universal Input Module:
