HY-TTC 94 – High Safety Controller

HY-TTC 94 is the top-level electronic control unit of the HY-TTC 50 controller family, offering enhanced flexibility and safety. It is designed to comply with the ISO/EN 13849 international standard. It comprises a main CPU for executing the user application and a smaller diagnostic CPU, which continuously monitors the main CPU and the safety-critical inputs and outputs. In case an error is detected, an internal switch opens, disconnecting all output stages from power supply and shifting the vehicle to a safe state. These safety features prevent uncommanded movements of the vehicle and equipment, thereby ensuring safe working conditions for users. HY-TTC 94 fulfills PL d (Performance Level d) requirements.

In many applications there is a growing demand for data transmission inside the vehicle network. On big and complex machines several CAN busses are being used for the various systems. To meet this demand HY-TTC 94 is equipped with 4 CAN channels.

As a member of the HY-TTC 50 family HY-TTC 90 supports a broad range of applications, including low-cost as well as high-availability applications in off-highway vehicles.
