|TestEquity F4T Touch Screen Controller|
The F4T is Watlow's next-generation process controller. Featuring a touch-screen interface, it's exceptionally easy and intuitive to use. The F4T is based on field-hardened electronics and robust algorithms already deployed in hundreds of thousands of installations worldwide. Watlow and TestEquity have worked closely together to refine this controller for use in TestEquity Environmental Chambers.

F4T Features and Benefits
Profile archiving and transfer via USB Flash Drive
Profiles can be exported and imported as individual files via USB flash drive. This is useful for transferring profiles between different chambers and for archival purposes. The profile files contain all the profile steps that would ordinarily be entered via the front panel or Composer software. The complete F4T Configuration File (snapshot of controller configuration and all profiles) can also be easily exported and imported via USB flash drive.
Data Logging with transfer via USB Flash Drive
Data Logging can be enabled at any time and will log a fixed list of parameters to a .csv file. Log intervals from 0.1, 0.2, 0.5, 1, 2, 5, 10, 15, 30 seconds, 1, 2, 5, 10, 15, 30, 60 minutes can be selected. All datalog files are stored in internal memory until transferred to a USB flash drive.
F4 Compatibility Mode
For the purpose of making an easy transition from the F4 to the F4T controller using Modbus, a special set of the most commonly used F4 registers were created. In the F4 Compatibility Mode, commands for Temperature/Humidity Set Point, Actual Chamber Temperature/Humidity, and Event Outputs are identical to the F4, so you can used your existing software on the new F4T.
The F4T accepts SCPI commands for reading the chamber temperature/humidity and reading/writing the temperature/humidity set point via Ethernet port 5025. The complete command set for all functions remain availible via Modbus.
The F4T allows you to easily create profiles...

F4T Retrofit Kit Available for Existing TestEquity Environmental Chambers
Add a modern controller to your existing TestEquity temperature chamber or temperature/humidity chamber. The F4T fits in the same cutout as the original F4 controller. Simply remove the original F4 controller, replace it with the new F4T controller, and attach the wires. You will need to drill holes to accommodate the added Ethernet and USB connectors if you want that additional functionality.
