The Emerson Trex and the 475 Field Communicator are two good choices if you’re trying to decide which field communicator to get for your calibration and maintenance work. Choosing can be aided by the following brief summary:

1. Design and Usability

  • Trex: The Trex is designed with modern technology in mind. It has a touchscreen interface that’s intuitive and user-friendly. It’s also rugged and built to withstand tough field conditions.
  • 475: The 475 has a more traditional design with a physical keyboard and a smaller screen. While it’s durable and reliable, it lacks the modern touch interface of the Trex.

2. Functionality and Features

  • Trex: This device offers advanced diagnostics and troubleshooting capabilities, allowing you to quickly identify and fix issues. It supports HART, FOUNDATION fieldbus, and Profibus PA devices. The Trex also includes Bluetooth and Wi-Fi capabilities, making it easier to update and connect to other devices.
  • 475: The 475 is also compatible with HART and FOUNDATION fieldbus devices, but it doesn’t support Profibus PA. It has basic diagnostics but doesn’t offer the same level of advanced troubleshooting features as the Trex. It lacks built-in Bluetooth and Wi-Fi, meaning updates and connectivity options are more limited.

3. Software and Updates

  • Trex: The Trex comes with the Device Care software suite, which provides enhanced capabilities for device configuration and management. Software updates are more straightforward with its wireless connectivity.
  • 475: The 475 uses older Field Communicator software. Updates can be a bit more cumbersome since they often require a physical connection to a PC.

4. Battery Life

  • Trex: Offers a longer battery life, which is crucial for fieldwork where recharging options might be limited.
  • 475: While still decent, the battery life of the 475 is shorter compared to the Trex.

5. Price

  • Trex: Generally, the Trex is more expensive due to its advanced features and modern design.
  • 475: The 475 is typically less expensive, making it a more budget-friendly option for those who need basic functionality.
