TRICONEX 3664 双数字输出 足够的冗余

产品技术要求：

TRICONEX 3664双数字输出(DDO)模块沿单个并行或串联路径接收来自主处理器的输出信号，并分别对每个交换机应用2-out- 3投票过程。开关产生一个输出信号，然后传递到现场终端。而TMR上的四倍输出电路TRICONEX 3664模块为所有关键信号路径提供多重冗余，双电路提供足够的冗余以确保安全运行。TRICONEX 3664 DDO模块针对那些低成本比最大可用性更重要的安全关键控制程序进行了优化。

Dual Digital Output (DDO) modules receive output signals from the Main Processors along a single parallel or series path, and applies a 2-out-of-3 voting process individually to each switch. The switches produce one output signal which is then passed to the field termination. While the quadruplicated output circuitry on TMR modules provides multiple redundancy for all critical signal paths, dual circuitry provides just enough redundancy to ensure safe operation. DDO modules are optimized for those safetycritical control programs where low cost is more important than maximum availability.
