Description
The OM-LGR-5320-Series has been discontinued. Please click here
to see Omega's offering of Data Acquisition Modules.
The OM-LGR-5320 Series are highspeed, standalone data loggers for
analog and digital signals. Each module offers 16 analog inputs,
16 digital inputs, one single Form C relay (0.5A) digital output for
triggering/alarming, and four counter/encoder inputs. These
devices allow users to collect high-speed correlated analog and
digital data without a computer. OM-LGR-5320 devices perform
high-speed, correlated measurements, up to 200 kS/s,
directly to a Secure Digital (SD) or SDHC memory card. Utilizing the
advanced analog and digital triggering options, users can collect
data to monitor systems and events without dedicating a PC. The
OM-LGR-5320 loggers include easyto-use DAQLog software to configure
the devices and retrieve data via the USB interface or SD memory card.
Three models are available in the OM-LGR-5320 Series. The
OM-LGR-5325 features up to ±10V analog inputs, 100 kS/s sampling,
four conventional counter inputs (non-quadrature), and singlechannel
trigger modes. The OM-LGR-5327 features up to
±30V analog inputs, 200 kS/s sampling, four quadrature encoder
inputs, and multi-channel trigger modes. The OM-LGR-5329 includes
all the functionality of the OM-LGR-5327 plus isolated digital inputs.
Analog Input
16SE/8DE analog inputs are included on each data logger.
The OM-LGR-5325 features multiple analog input gain ranges
up to ±10V. The OM-LGR-5327 and OM-LGR-5329 add a ±30V
analog input range for increased measurement capability. Each data
logger provides 16-bit resolution.
Correlated, High-Speed Sampling
The OM-LGR-5327 and OM-LGR-5329 can sample input
data at up to 200 kS/s while the OM-LGR-5325 offers a 100 kS/s
sample rate. Each module can sample all analog, digital, and
counter data synchronously, making it easy to compare time
between all channels.
Configuration, Data Storage, and Retrieval
Each data logger can be configured through the SD memory card or via
the on-board USB port. Simply configure the logging session with
the included DAQLog software. All logging parameters are captured
on the SD memory card. A 4 GB SD memory card is included with each
data logger. Memory cards up to 32 GB are supported for extended
data collection. Data is retrieved by removing the
SD memory card from the logger
and uploading to a PC or by
connecting to the USB port on the logger.
Triggering
OM-LGR-5320 Series data loggers offer multiple triggering options for
starting and stopping a data scan. These options vary by model.
The OM-LGR-5325 features single-channel analog and digital
triggering. The OM-LGR-5327 and OM-LGR-5329 offer multi-channel
and pattern triggering options. Multiple trigger options allow
collection of only the desired data. External clocking is also supported.
Digital I/O
16 digital inputs are included with each data logger. These inputs can
be sampled synchronously with analog input data.
The OM-LGR-5325 and OM-LGR-5327 feature up to
28V digital inputs while the OM-LGR-5329 features up to 30V
digital inputs. The digital inputs on the OM-LGR-5329 also provide
500 Vdc isolation. Each data logger also features one digital output relay
channel. The Form C relay can be programmed via the included
DAQLog software to alarm when desired conditions are met.
Counters
Four counter inputs are built into the OM-LGR-5320 Series.
The OM-LGR-5325 features conventional up/down counters.
The OM-LGR-5327 and OM-LGR-5329 include quadrature
and conventional counter inputs. Multiple count modes are also
supported.
Pushbutton Logging Controls
Onboard one touch logging controls are featured on each module for quick and simple operation. These controls can be used for a variety of functions including:
• Configuration loading from SD memory card
• Start/stop logging
• Force trigger/user event
• Device reset
• Control of status LEDs
LEDs on each module provide instant logging and trigger status
and activity state.
DAQLog Software
DAQLog Software is an easy to use application included with each
OM-LGR-5320 Series data logger. DAQLog uses a spreadsheet style
interface that allows simple setup of channel and logging parameters.
DAQLog includes the following functions:
• Data logger configuration
• Channel setup
• Trigger setup
• Data conversion
• Scan rate and acquisition length
• Trigger, event, and alarm parameters
Data can be saved in .csv format for easy import into Excel®.
