The OM-LGR-5320 Series are highspeed, standalone data loggers foranalog and digital signals. Each module offers 16 analog inputs,16 digital inputs, one single Form C relay (0.5A) digital output fortriggering/alarming, and four counter/encoder inputs. Thesedevices allow users to collect high-speed correlated analog anddigital data without a computer. OM-LGR-5320 devices performhigh-speed, correlated measurements, up to 200 kS/s,directly to a Secure Digital (SD) or SDHC memory card. Utilizing theadvanced analog and digital triggering options, users can collectdata to monitor systems and events without dedicating a PC. TheOM-LGR-5320 loggers include easyto-use DAQLog software to configurethe devices and retrieve data via the USB interface or SD memory card.
Three models are available in the OM-LGR-5320 Series. TheOM-LGR-5325 features up to ±10V analog inputs, 100 kS/s sampling,four conventional counter inputs (non-quadrature), and singlechanneltrigger modes. The OM-LGR-5327 features up to±30V analog inputs, 200 kS/s sampling, four quadrature encoderinputs, and multi-channel trigger modes. The OM-LGR-5329 includesall 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 rangesup to ±10V. The OM-LGR-5327 and OM-LGR-5329 add a ±30Vanalog input range for increased measurement capability. Each datalogger provides 16-bit resolution.

• 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 statusand activity state.
DAQLog Software
DAQLog Software is an easy to use application included with eachOM-LGR-5320 Series data logger. DAQLog uses a spreadsheet styleinterface 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®.
