Digilent WebDAQ 904 Universal Input Data Logger

Overview

The Digilent WebDAQ 904 is a stand-alone internet-enabled data logger with universal input, specifically engineered for remote control and monitoring. Capable of high-precision measurements from up to four analog inputs, it can interpret various signals from different sensors including strain gauges, RTDs, thermocouples, and load cells. It features four isolated digital I/O bits that can function as trigger inputs or alarm outputs. The WebDAQ 904 eliminates the need for a separate computer or extra software, as all necessary intelligence is integrated into the device. Through the built-in web server, users can configure applications, log data, modify digital outputs, send alerts based on conditions, and access real-time data from any web-enabled device, regardless of location. The device is housed in a heavy-duty chassis designed for robust industrial use.
