Descrição

The OMB-NET6000 Series with Encore software combines accurate, Ethernet-based DAQ modules with powerful, easy-to-use software. OMB-NET6000 Series devices feature integrated signal conditioning and a modular design with built-in channel expansion capability expandable (by adding additional
OMB-NET6000 Series Modules). Because the OMB-NET6000 Series uses an Ethernet connection, devices can be connected directly to a PC or used in remote configurations utilizing multiple devices. Devices are offered for voltage, thermocouple, or direct strain inputs.

Each device includes 12 analog input channels. The OMB-NET6220 offers 12 voltage inputs, BNC connectors, 16-bit resolution, and a 100 kHz per channel sample rate. The OMB-NET6222 is a 12-channel, 24-bit thermocouple input device. The OMB-NET6224 offers direct strain gage inputs, 24-bit resolution, and a 50 kHz per channel sample rate. The OMB-NET6230 and OMB-NET6231 are high-speed, isolated voltage input devices. Each device also includes 8 digital I/O channels. Included with each OMB-NET6000 Series device is new Encore interactive measurement software. Encore combines an intuitive user interface with robust functionality. It allows users to quickly configure hardware, develop and customize data displays, analyze data with built-in analysis tools, and provides the ability to develop comprehensive test reports. Utilizing the connectivity of an Ethernet based system, multiple OMB-NET6000 series devices can be combined to build expandable, mixed signal systems. These systems can be used in a central location, or in distributed or remote configurations.

ANALOG INPUTS
OMB-NET6220
The OMB-NET6220 is equipped with 12 analog input channels with a ±10V range. Each analog input provides 16-bit resolution with a maximum 100 kHz per channel sample rate. All channels are sampled simultaneously.

OMB-NET6222
The OMB-NET6222 is equipped with 12 thermocouple input channels. Inputs are also equipped with a ±80 mV range. Each analog input provides 24-bit resolution with a 2 S/s sample rate per channel. All inputs are sampled simultaneously.

OMB-NET6224
DIRECT STRAIN GAGE INPUTS
The OMB-NET6224 is equipped with 12 analog input channels capable of measuring full-, half-, or quarterbridge sensors. Each of the 12 analog channels has its own 24-bit ADC and input amplifier allowing all 12 channels to be sampled simultaneously. The OMB-NET6224 also includes anti-aliasing filters. All strain input signals are attached via 12 RJ50 connectors mounted on the front of the module. The OMB-NET6224 features direct strain gage inputs. Half or full-bridge sensors are supported. Quarter-bridge sensors are also supported using an external resistor. The OMB-NET6224 is also 100% software programmable. Excitation, auto-zero, and shunt calibration are each adjusted in software without relying on manually adjusted trimpots which can cause increased error and drift. Excitation is provided by the OMB-NET6224 and can be software selected for 2.5V, 3.3V, 5V, or 10V. For excitation values beyond those listed, an external excitation source may be used. Connectors are provided on the front of the unit for excitation source wiring.

SHUNT CALIBRATION
Shunt calibration enables each channel to be put into a known imbalance condition to set or verify channel calibration. Shuntcal allows a full scale gain to be set without physically loading the bridge
to capacity.

REMOTE SENSING
Remote sensing automatically and continuously corrects for voltage drop errors in excitation leads.

SIGNAL CONNECTIONS
The 12 strain gage inputs on the OMB-NET6224 are accessed via 12 RJ50 front panel connectors.
12 user specified connector modules are included with the OMB-NET6224.

FULL- AND HALF-BRIDGE
CONFIGURATIONS
The OMB-NET6224 supports full- and half-bridge configurations directly. Users can connect to the RJ50 front panel connectors or use the OMB-NET-CN-268 12-pin screw terminal break-out connector module.

QUARTER-BRIDGE
CONFIGURATIONS
For quarter-bridge configurations the OMB-NET-CN-269 and OMB-NET-CN-270 feature 120 Ω and 350 Ω internal bridge completion resistors respectively. The OMB-NET-CN-269 and OMB-NET-CN-270 feature an RJ50 female connector one end and screw terminals on the other. One module is required for each channel.

OMB-NET6230 and OMB-NET6231
The OMB-NET6230 is equipped with 12 analog input channels with a ±10 V range. The OMB-NET6231 includes a ±60 V range. Each analog input features a 24-bit ADC with a maximum 50 kHz sample rate per channel. All channels are sampled simultaneously. The OMB-NET6230 and OMB-NET6231 also include 250 Vrms channel-to-channel isolation for increased signal integrity and protection.

DIGITAL I/O
OMB-NET6000 Series modules include eight digital I/O lines. All eight lines are accessible via a 9-pin female DSUB connector located on the rear panel of the unit. Each digital I/O bit can be programmed individually to be either an input or an output.

COUNTERS
There are four 32-bit counters built into each OMB-NET6000 Series module. They are accessed through the 9-pin female DSUB connector located on the rear of the unit. Each counter has a maximum 20 MHz input frequency and can be used in counter or encoder (A, B, and Z) modes.

TRIGGERING
A variety of trigger modes are supported by the OMB-NET6000 Series. A wide selection of programmable analog and digital trigger modes are available for starting an acquisition. All trigger modes, along with the number of scans and the sample rate for preand post-trigger data, are software programmable prior to the start of a scan sequence.

SYSTEM POWER CONNECTION
The OMB-NET6000 Series modules offer the flexibility to be powered either directly from a 19 V to 30 VDC source, or via the included OMB-NET-TR-60U AC power adaptor.

ETHERNET FEATURES
The OMB-NET6000 Series transfers acquired data to the PC via 10/100BaseT Ethernet, allowing a continuous stream of data to be collected and stored in a PC’s memory or hard drive. The most common and highest performance connection is with dedicated, point-to-point Ethernet link between the PC and the OMB-NET6000 Series module. With an enterprise-wide Ethernet network connection, any number of OMB-NET6000 Series modules can be connected to the network.

MULTI-UNIT SYNCHRONIZATION
Multiple OMB-NET6000 Series modules can be synchronized via the rear-panel SYNC ports on each unit. After connecting each module to an Ethernet port, simply connect multiple OMB-NET6000 Series modules together using SYNC cables (OMB-CA-74-1). Encore software provides the capability of setting one of the OMB-NET6000 Series modules as the master and the others as slaves. The sampled data phase relationship among channels between multiple devices is dependent on the “Channel SYNC Skew” specification for each device.

ENCORE SOFTWARE Overview
Encore is a premier data acquisition software package and is included with each OMB-NET6000 Series module. Encore combines ease of use with advanced functionality, including customizable data layouts, powerful analysis, and reporting capabilities. Instead of having a program to log data, another to analyze, and a third to develop report data, Encore includes the functionality of all three into one package, thus shortening the learning curve, and saving time and cost.

CONFIGURATION
Easy-to-use set-up wizards provide rapid hardware configuration. Encore allows you to go from setup to taking measurements in minutes. Users can select one or more available devices from Encore’s Hardware Configuration dialog. Encore allows you to configure the basic acquisition or generation options, such as channel selection, acquisition rate, number of points, and input range. You can also configure start and stop triggers. In addition, within the Channel View table, users can enable (or disable) channels, select measurement type, enable logging, perform mx+b calculation, and more. Channel View configurations can also be shared among multiple projects.

MEASUREMENT
Encore allows you to develop data displays quickly with an intuitive, drag-and-drop interface. Encore also offers the ability to easily change plot colors, overlay channels (including previously recorded data), and access multiple devices. You can also display data in a variety of ways including; charts and graphs, meters, gauges, and tanks. Additionally, you can export data to other formats including Excel, ASCII and DIAdem.

TRIGGERING
A variety of programmable analog and digital trigger conditions are available for starting and stopping an acquisition within Encore. Analog triggers include Rising Edge, Falling Edge (with hysteresis), Above Level, Below Level, Inside Window, and Outside Window. Digital triggers include Rising Edge, Falling Edge, Level High, or Level Low. In addition, the Duration trigger may used to stop an acquisition after a specified time.

ANALYSIS
Included analysis options make Encore an advanced software package. Features include FFT, power spectrum, statistics, peak value, and RMS calculation. In addition, you can also create custom formulas using Encore’s Create Calculated Signal function. Data can also be viewed in the playback work area. Analysis can be computed on live data as well as logged data (post processing).

ANALYSIS OPTIONS INCLUDE:
• Statistics: Standard Deviation, Mean, and Variance
• Peak: +Peak, -Peak, and Peak-Peak
• RMS
• DC
• FFT
• Power Spectrum
• Minimum
• Maximum

EXPORT TO EXCEL®
Signals can be exported from Encore to Microsoft Excel. When exporting signals from Encore to Microsoft Excel, the following information is exported:
• Signal name
• Export date and time
• Signal units
• Data values
Encore offers sophisticated, builtin test reporting capability which provides the ability to present data in a professional manner. With Encore’s test report capability, users can easily develop in-depth test reports. Within Encore’s Project Report tab users can drag signals from the application directly into the report and then enter text, change fonts, import images and print or export reports. Once the report is complete, you even have the ability to acquire new data and easily update any previous report, without re-creating the report. The report can be edited throughout the life of the project.
