More reliability for safety-critical applications

TTC 200 is a programmable electronic control unit for sensor/actuator management. It can be used, by means of many configurable I/Os, with different sensor and actuator types. The control unit is part of an extensive and compatible product family designed specifically for machines operating in rough environments and at extreme operating temperatures. Its robust injection-molded aluminum housing shields from electromagnetic disturbance and mechanical stress. A 40 MHz Motorola MPC555 integrated micro-processor supplies the necessary processing power.

TÜV NORD has certified TTC 200 according to the international IEC 61508 standard. The TTC 200 stand-alone version fulfills SIL 2 requirements; two TTC 200 ECUs in a TTP network have been the first to achieve SIL 3 certification. Its compliance with IEC 61508 enhances development processes, resulting in higher product quality. Costs of defective and idle machinery can be kept at a minimum.

All TTC 200 inputs and outputs are protected against electrical surges and short circuits. In addition, internal safety measures allow the detection of open load, overload and short circuit conditions at the outputs. Proportional hydraulic components can be connected directly to the current controlled PWM outputs. Hydraulic valves with integrated power stages can be operated by two analog output signals. CAN, TTP, RS-232 and LIN / TTP/A / ISO-K are available for serial communication.

Customers that use the TTC 200 with CoDeSys can reconfigure all output stages to act as inputs. This unparalleled freedom enables system designers to increase the number of available inputs in a very flexible way, allowing design of complex systems with up to 23 timer inputs.

At the basic level, the unit may be programmed in C. In addition, a TTP-Matlink library for MATLAB/ Simulink and an I/O library are available for TTC 200. CoDeSys, which is one of the most common IEC 61131-3 programming systems that runs under Microsoft Windows, can be also be used for programming the TTC 200.
