The Digilent WebDAQ 904 Internet Enabled Universal Input Data Logger is a sophisticated, stand-alone device engineered for remote monitoring and control without the necessity of a PC or additional software. It integrates an embedded web server, allowing users to configure applications, log data, update digital outputs, and send notifications based on alarm conditions. This functionality is accessible from any location and device equipped with a web browser. The WebDAQ 904 is capable of high-accuracy measurements from up to four analog inputs, accommodating various sensors such as strain gauges, RTDs, thermocouples, and load cells. It features four isolated digital bits that can serve as trigger inputs or alarm outputs, making it suitable for industrial applications due to its robust chassis.

The device supports multiple signal types, including voltage, current, RTDs, thermocouples, resistance, and bridge-based sensors, with a 24-bit A/D converter and a sample rate of up to 100 samples per second per channel. Data can be logged to internal storage or mapped network storage, with an internal memory capacity of 3GB, and options for additional storage via SD card and USB slots. The built-in web server facilitates access from any web-enabled device, providing alarming and notification capabilities through email and SMS messaging. Data can be exported in various formats such as CSV, UFF, or binary for further application use.

The WebDAQ 904 offers easy and flexible task scheduling without the need for driver software installation. It supports WiFi connectivity (with an optional dongle) and includes an Ethernet port for network or PC connections. The device’s embedded operating system and web server deliver a comprehensive solution for stand-alone data logging and alarming, enabling users to monitor and control applications from anywhere using a web browser. The web server is optimized for both desktop and mobile use, allowing data acquisition tasks to be performed from phones, tablets, and laptops through an intuitive user interface. For advanced custom functionality, a RESTful API is available, enabling real-time data retrieval, system information access, and integration with popular data dashboards, cloud applications, or custom programs.
