HY-TTC 200 is a programmable electronic control unit for sensor/actuator management. The controllers can be used, by means of many configurable I/Os, with different sensor and actuator types. The robust aluminum diecast housing shields from electromagnetic disturbance and mechanical stress. A 40 MHz Freescale MPC555 integrated microprocessor supplies the necessary processing power.

All 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 pulse-width modulation outputs. Hydraulic valves with integrated power stages can be operated by two analog output signals. CAN, TTP, RS-232 and LIN are available for serial communication.

HY-TTC 200 is certified according to the IEC 61508, the international standard governing the functional safety of programmable electronic systems. The stand-alone version fulfills SIL 2 (Safety Integrity Level 2) requirements; the network version with TTP meets the requirements of SIL 3.
