Electronic Control

HY-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. Its robust aluminum diecast housing shields from electromagnetic disturbance and mechanical stress. A 40 MHz Freescale MPC555 integrated microprocessor supplies the necessary processing power.

All HY-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 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.

"Our comprehensive certification process has shown that HY-TTC 200 provides a maximum level of reliability. It is thus best suited for off-highway vehicles in on-road traffic."
