# Data Logger, Universal ![Product image](https://novapart.co/image/farnell:3866302/) **URL**: https://novapart.co/products/OM-SQ2040-4F16-WIFI/data-logger-universal **SKU**: OM-SQ2040-4F16-WIFI **Manufacturer**: OMEGA **Price**: €3737.7300 **Stock**: 10+ ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (17-Jan-2022) | | Product Range | OM-SQ2040 Series | | Data Logger Type | Universal | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:3866302/) ## _**Portable Data Logger**_ ## **OM-SQ2040** - U **16 True Differential or 32 Single-Ended Universal Analog Inputs for Voltage, Current or Resistance Measurements—Plus 2 High Voltages, 4 Pulse and 8 Digital Event/State Inputs** - U **Analog Inputs Can Be Used with Thermistors, Thermocouples, 2, 3 or 4-Wire RTD Temperature Sensors and 4 to 20 mA Signals** - U **User Selectable Logging Rates of Up to 100 Hz on Up to 4 Channels** - U **Download of Internal Data to Removable MMC/SD (Multi Media Card/Secure Digital) Memory** - U **Large Non-Volatile Internal Memory—Data Retention is Virtually Indefinite** - U **Ethernet, Wi-FI (On the OM-SQ2040-2F16-WIFI and OM-SQ2040-4F16-WIFI) USB and RS-232 Communication Ports** - U **Sensor Power and FET Alarm Outputs For Use With External Devices** - U **Easy Access to Information Using the 2 Line, 20 Character LCD and Push Button Panel** - U **Calculated Channels Derived from Real Channels Using Advanced Mathematical Functions** The OM-SQ2040 Series combines a higher channel count with the same high performance, comprehensive features and universal inputs as the OM-SQ2020 in a neat compact and portable instrument. Using multiple 24-bit analog to digital convertors, twin processors and removable memory options provide great flexibility to handle a wide range of complex and demanding multi-channel applications. The OM-SQ2040 series are the ideal data loggers for industrial, scientific research and quality assurance applications. The OM-SQ2040 provides stand-alone data acquisition, advanced networked solutions and data analysis straight out-of-the-box. ## **Input Connections** The OM-SQ2040-2F16 data logger has two analog to digital converters (A/D’s) which increases logging flexibility over the OM-2020-1F8 model. The first corresponds to inputs on blocks A, B, C and D and the second corresponds to inputs on blocks G, H, J and K. Each connection block will accept up to 2 differential inputs or up to 4 single-ended inputs (it is not possible to mix single ended and differential inputs on a block). The OM-SQ2040-4F16 data logger has four analog to digital converters (A/D’s) which increases logging flexibility over the other OM-SQ2020 and OM-SQ2040 models. The first corresponds to inputs on blocks A and B, the second corresponds to inputs on blocks C and D, the third corresponds to inputs on blocks G and H and the fourth corresponds to inputs on blocks J and K. Each connection block will accept up to 2 differential inputs or up to 4 singleended inputs (it is not possible to mix single-ended and differential inputs on a block). **OM-SQ2040-2F16-WIFI data logger shown smaller than actual size.** ## **Concurrent Sampling** The OM-SQ2040 series uses multiple analog to digital converters that enables true concurrent sampling and logging. This allows the user to configure up to 4 channels to log at a rate of 100 Hz while retaining different sample speeds on other channels. This makes the OM-SQ2040 ideal for measuring dynamic parameters that change at different rates such as temperature and pressure. ## **Communications** Ethernet, Wi-Fi (on the OM-SQ2040-2F16-WIFI and OM-SQ2040-4F16-WIFI) USB and RS-232 serial ports are built-in. This allows quick connection to either a PC based TCP/IP network, a wireless to PC connection or to a modem for remote data downloading. **1** This flexibility enables global data access and retrieval as well as complete system integration of the OM-SQ2040 series into complex and critical applications. ## **Multiple Configurations Stored in the Logger** Up to six logger configurations (channel type, names, logging speeds, triggers, etc.), together with the current configuration, can be held in the logger’s internal memory. Additional configuration settings can also be loaded from the external MMC/SD memory card. This allows the operator to quickly and easily switch between logger configurations without the need for a PC. ## **Comprehensive Software Configuration** The OM-SQ-SOFT software (supplied with the OM-SQ2040 series data loggers) allows logger configuration, data download and data export while giving the user full control over the OM-SQ2040. You can also zoom in on areas of interest, use a cursor to pick out exact values, times and dates, get astatistical summary of your data, set high and low alarm thresholds and, using the calculation function, you can create new virtual channels from existing channels. The OM-SQ-SOFT-PLUS software also incorporates a report generation facility, which allows you to create custom report templates consisting of a title page with descriptive text, headers and footers, graphs, tabular list of data, statistics and data logger setup information. Templates can be setup with any of these combinations and saves time when preparing similar presentations of data. The optional OM-SQ-SOFT-PLUS software gives the user access to many advanced data analysis and data archiving/transfer features. The optional OM-SQ-SOFT-PLUS software lets you quickly and easily analyze the data from your OM-SQ2040 data logger in a familiar Explorer style interface. Data can be displayed with 2 different auto scaling Y-axis. This is particularly useful when displaying widely varying data from different sensors on one graph. **==> picture [108 x 16] intentionally omitted <==** **----- Start of picture text -----**
