TC-7 Control System

The latest generation of heavy-duty gas turbine controllers covering every aspect of turbine performance

Digital Gas Turbine Control System


We offer the latest generation of heavy-duty gas turbine controllers, Ansaldo Thomassen’s TC-7, covering every aspect of turbine performance. 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, for seamless integration in existing or new DCS systems.

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. This control system also offers the hardware and software flexibility your power plant needs to remain relevant, reliable – and, above all – profitable.

Easily Echangeable


The TC-7 can be easily exchanged with a Mark I, Mark II, Mark IV or Mark V and no mechanical support change is needed. Electrical and instrumentation changes are minimized. The cable entrance is at the bottom therefore no additional marshalling boxes are needed for cable extension. Instrumentation can be adapted to fulfil SIL requirements. Approved flame detectors and the gas nozzle start pressure switch are common instruments to be adapted.

Currently we have over 15 TC-7 control systems installed worldwide.
