WHAT IS THE TC-7?

The latest generation of heavy-duty gas turbine controllers, the Thomassen TC-7, is the result of years of R&D
covering every aspect of turbine performance. As a high-performance, cost-effective solution offering a higher
degree of scalability, the TC-7 can be seamlessly integrated into any existing or new plant control system.

Based on the proven design of Simatics PCS7®, the TC-7 is a digital control system that takes advantage of an open-architecture design and non-proprietary hardware, keeping maintenance costs to a minimum, while ensuring maximum performance.

This state-of-the-art approach has been implemented throughout the system – right down to concerns for safety, where the TC-7 has TÜV approval and meets the requirements of SIL 3 according to IEC 61508 for safety-related turbine functions. You will also find that the TC-7 offers the hardware and software flexibility your plant needs to remain relevant, reliable – and, above all – profitable.

TC-7 DESIGN

At the heart of the TC-7 are SIMATIC® 417FH series controllers. Thomassen TC-7 control systems can be of either simplex or redundant design. The system is designed for ease of use and its open architecture will allow for seamless integration in existing or new DCS systems.
The hot-backup facility in redundant configuration will allow for a minimum of downtime in case of program changes.
Due to extensive design constraints and rigorous testing, the TC-7 system and hardware design are infallible. The software-configured I/O modules are designed for easy insertion without requiring a working understanding of hardware configuration.

TC-7 FEATURES

As versatile as it is fully functional, the TC-7 is the centerpiece for a variety of applications such as heavy-duty gas turbines, with or without LEC or DLN systems, compressor drives, and generator drives. As the turbine control system is equipped with failsafe I/O, fire detection can easily be integrated in the control system.
Optional items for the TC-7 include generator control systems, generator protection systems, compressor control systems, boiler management systems, and balance of plant control.

The Thomassen TC-7 isn’t just a product engineered to optimize turbine performance – it provides re-assurance, confidence, and peace of mind.
