Introduction

The SCADA 3000 Universal Input Module is an optional component for use with the SCADA 3000 system. The input channels are identical to those included on the SCADA 3000 main unit. The Universal Input Module features eight channels that can be configured to interface with several different types of sensors and transducers, including: Normally Open/Normally Closed dry contacts, digital logic, Run time Accumulation, 0-5V analog, 4-20mA analog and 10K thermistor (ºC & ºF). The module features 12-bit resolution, differential inputs, 24V supply for powering 4-20mA loops and low-power operation. Each input is protected by a 1500 Watt transient suppressor. In addition, a microprocessor watchdog circuit is integrated to maintain system reliability. LED indicators are provided to show system power and module operation via a blinking pulse LED.

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.

UIM-7
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 be 4-Conductor Twisted Pair (shielded or unshielded) with a nominal impedance of 120 (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.
BUS TERM

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.
Wiring Minimum Distance Wire Gauge
700' #24 AWG
1500' #22 AWG
2500' #20 AWG

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 input. The configuration jumper should be set to the TMP/DRY position. The figure below shows how to connect a dry contact sensor:

1OK Thermistors

The Universal Input Module is compatible with 10K thermistors that match the curve data listed in the table in Appendix A. The monitoring temperature range of the 10K thermistor is ­80 to 300ºF (-62º to 149ºC). 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 input. The configuration jumper should be set to the TMP/DRY position.

Analog Voltage Output Transducers (0-5VDC)

The Universal Input Module is compatible with transducers that produce an analog output of 0 to 5VDC. You can program High and Low table values from the SCADA 3000 Software to scale the signal to the appropriate values.
Analog voltage output devices can be connected directly to the input terminals but be sure to following the polarity markings on the module. Choose an input and connect the wires to the corresponding screw terminals for that input. The configuration jumper should be set to the storage position as indicated in the diagram below:

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 set to the 4-20mA position as indicated in the following diagrams:

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:
Temperature Humidity Power (Voltage level, Current level, Power consumption) Pressure Flow Gases (Carbon Monoxide, Carbon Dioxide, Oxygen,…) Liquid Level Refrigerant Leak Detector Water Detector Weather (wind speed, wind direction, barometric pressure, rainfall) Vibration
Sensors to monitor just about any condition are available. See the Accessories listing in Appendix G of the main unit User’s Manual or contact Phonetics for more information.
