Digilent WebDAQ 904 – Internet Enabled Universal Input Data Logger

• WebDAQ 904 universal input data logger for remote monitoring, control; Embedded web server
• Support for voltage (up to +/- 60V), current, RTD, thermocouples, resistance, and bridge-based sensors
• Four simultaneous analog inputs
• (2) USB Ports, SD Memory Card slot; Internal 3GB memory
• Built-in web server allows access from any device with a web browser

The WebDAQ 904 is a stand-alone, universal input data logger designed for remote monitoring and control. All the intelligence is built into the WebDAQ, eliminating the need for a PC or additional software. By using the embedded WebDAQ web server, users can easily configure simple or sophisticated applications, log data, update digital outputs and/or send notifications based on alarm conditions, and view real-time data from any location and any device with a web browser. The WebDAQ 904 performs high-accuracy measurements from up to four analog inputs. Users can measure several signals from sensors such as strain gauges, RTDs, thermocouples, and load cells. Four isolated digital bits can be used as trigger inputs or alarm outputs. Housed in a heavy-duty chassis, the WebDAQ 904 is rugged enough for industrial applications.

There are three devices in the WebDAQ Series. Devices are available to log multiple signal types including voltage (up to +/-60 V), thermocouples, IEPE-based sensors like accelerometers, current, RTDs, resistance, and bridge-based sensors.

The WebDAQ Series embedded OS and web server provide an all-in-one package for stand-alone data logging and alarming. Users can monitor and control their applications from anywhere with a web browser. The WebDAQ web server is optimized for both desktop and mobile use. Users can perform data acquisition tasks from phones, tablets and laptops with a single, intuitive user interface.

An embedded web server provides a clean, intuitive interface to access all configuration and data management tasks. Hardware, trigger, and alarm settings are contained in a single task, or job. Multiple jobs can be run in a schedule for more complex data logging applications. For example, users can create a schedule of jobs in which one job automatically runs after an alarm condition is triggered on a different job, such as when a temperature is reached or when a digital input changes. Start or stop the acquisition based on analog or digital thresholds, alarm states, or date/time values. On-demand push button triggering is also supported.
