More reliability for safety-critical applications

The 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.

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.
The TTC 200 was designed to comply with the IEC 61508 international standard. The stand-alone version fulfills SIL 2 requirement; the network version with TTP meets the requirements of SIL 3.

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.
