- Built-in web server 

- Remote monitoring and control 

- WiFi support 

web server, users can easily configure simple or sophisticated applications, log sensor 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. Housed in a heavy-duty chassis, the WebDAQ 904 is rugged enough for industrial applications. 

## **Integrated Software and Hardware** 

The WebDAQ Series embedded OS and web server provides 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.

## **Remote Access and Control** 

Install the WebDAQ 904 on any network and access it using any device with a web browser to remotely monitor and control all operations. 

## **Wireless Communication** 

After the WebDAQ is detected on a wired network, users can connect an approved WiFi adapter to the rear panel and communicate with the WebDAQ over a wireless network. Refer to our website for a list of the WiFi adapters approved for use with WebDAQ Series hardware. 

## **Flexible Triggering** 

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. 

## **WebDAQ Web 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. 

_Device-independent operation lets you remotely monitor and control the WebDAQ 904 from any device with a web browser._

**WebDAQ 904 Datasheet – Rev 1, June 2024** 

## **Introduction** 

## **Easy Setup – Powerful Capabilities** 

Jobs are the building blocks of WebDAQ. The ability to define different data logging jobs, or tasks, and add them to a schedule unleashes flexibility not seen in any other data logger. 

Whether you want to set up a simple logging task or a complex task, jobs and a schedule make it easy and straightforward. 

## **What is a Job?** 

The basic building block of WebDAQ, a job defines channel configuration, logging options, start and stop conditions, and alarming. 

## **What is a Schedule?** 

A schedule is a collection of jobs that gives flexibility to dynamically change data logging attributes, such as sampling rate, active channels configuration, or alarm levels. 

## **Example:** 

Switching from static acquisition to dynamic acquisition. 

## **1 Schedule and 2 Jobs** 

Users can easily set up a job for a slow, static acquisition and a fast dynamic acquisition. When a trigger condition is met (i.e. over/under alarm), Job 1 (slow acquisition) ends and Job 2 (fast acquisition) begins. When the trigger condition returns to normal, job 1 can be restarted. 

## **Clear, Concise, Data Displays** 

WebDAQ users don’t need to rely on the small screens and difficult to navigate displays of most other loggers. With WebDAQ’s intuitive web interface, users can easily see their data and alarm conditions in real time or after the acquisition is complete.

## **Features** 

## **Alarm and Event Notifications** 

Create multiple alarms using analog or digital channel sources. Configure alarms to reset and re-arm when the condition clears or reset them remotely with your browser. View the alarm status on the web interface. Users can configure one or more events to record when a job is started, stopped, or triggered, or if an error condition is detected. 

Receive alarm and event notifications on one or more addresses using email and SMS messaging. 

(high resolution mode). Refer to the Specifications section for the conversion times for all timing modes. 

## **Universal Input Modes** 

Each channel is configurable for a different input mode: 

- Voltage 

- Current 

- Thermocouples 

- RTD (4-wire and 3-wire) 

- Resistance (4-wire and 2-wire) 

## **Virtually Unlimited Storage** 

Store data files and configuration settings locally in internal flash memory or save to external media or network folders. Users can map a network drive or FTP server as the location to log data or store files. Easily transfer files between WebDAQ storage locations and mapped network storage locations. 

## **Share Folders** 

Users can share a WebDAQ storage location or specific folder over a local network. 

- Bridge-based sensors (half- and full-bridge, and other powered load cells) 

Measurement ranges vary for each type of measurement; refer to the Specifications section for range values per input mode. The max sample rate is 100 S/s per channel. 

Voltage and current excitation is provided for applicable input modes. Each channel has a built-in thermistor for cold-junction compensation (CJC) calculations when measuring thermocouples. An analog pre-filter removes noise that may be present in the signals prior to conversion. 

## **Real-Time Data Display** 

View data as it is acquired or from a stored file. Users can specify a range of data to view and zoom in or out. Data is plotted on strip chart and scalar displays. 

## **Control Read and Write Access** 

Users can control who can view and modify job settings by defining a password and setting the security level for the admin account. A “share” password can be used to access a shared folder or FTP server running on the WebDAQ. 

## **Run the Schedule on Startup** 

Automatically run the schedule when the system starts up. Multiple jobs in the schedule are run consecutively. 

## **Real-Time Clock** 

A real-time clock provides an absolute time reference for timestamping data. The clock can be set to any time zone and may be synchronized to the internet time server. 

## **Analog Input** 

The WebDAQ 904 provides four individually configurable channels of 24-bit universal analog input. All channels are measured simultaneously at rates of up to 10 ms (high speed mode) or 510 ms 

## **Timing Modes** 

The WebDAQ 904 supports high resolution, 50 Hz rejection, 60 Hz rejection, and high-speed timing modes. 

- High resolution mode optimizes maximum overall noise rejection and provides rejection of 50 Hz and 60 Hz noise. 

- 50 Hz rejection mode optimizes 50 Hz noise rejection. 

- 60 Hz rejection mode optimizes 60 Hz noise rejection. 

- High speed timing mode optimizes the sample rate. 

## **Isolated Digital I/O** 

The four isolated digital I/O lines can be used either as triggers to start or stop the acquisition or as alarm outputs. 

## **Flexible Power Requirements** 

Provide power with the 9 volt, 2.2 amp supply that ships with the device, or connect any 6 to 16 DC supply.

**WebDAQ 904 Datasheet – Rev 1, June 2024** 

## **Firmware Updates** 

Device firmware is bundled with the operating system and web server in one update file. This allows the WebDAQ to be updated in the field. 

## **Calibration** 

The WebDAQ is factory-calibrated using a NISTtraceable calibration process. Specifications are 

guaranteed for one year. Return the device to the factory for recalibration. 

## **REST API** 

The WebDAQ REST API allows users to communicate with the device outside of the web interface to retrieve information about the system, schedules, and jobs, get acquisition and alarm status, and to start/stop an acquisition.
