产品详细资料
如果需要,您可以将三处理器模块配置为此SIL3架构的变体。使用这种布置,处理器模块在无故障条件下以2oo3D运行,在检测到任何模块中的个故障时以1o2D运行。当检测到任何两个模块中的故障时,它们会降级到1o1D,并且当所有三个模块都出现故障时,会自动失效。数字输出模块•对于断电操作,一个数字输出模块足以满足SIL 3要求。然而,对于通电到动作操作,需要双数字输出模块。•必须在PFD计算中使用的MTTR内修复数字输出模块故障。模拟输出模块•模拟输出模块的故障安全状态电流小于2mA。•对于断电操作,一个模拟输出模块足以满足SIL 3要求。然而,对于通电到动作操作,需要双模拟输出模块。•必须在PFD计算中使用的MTTR内修复模拟输出模块故障。
If required you can configure triple processor modules as a variation of this SIL 3 architecture. Using this arrangement the processor modules operate in 2oo3D under no fault conditions and 1oo2D on the detection of the first fault in any module. They degrade to 1oo1D on the detection of faults in any two modules, and will fail-safe when there are faults on all three modules. Digital Output Modules • For de-energize to action operation one digital output module is sufficient for SIL 3 requirements. However, for energize to action operation, dual digital output modules are required. • A digital output module fault must be repaired within the MTTR which was used in the PFD calculation. Analogue Output Modules • The fail-safe state current of the analogue output module is less than 2mA. • For de-energize to action operation one analogue output module is sufficient for SIL 3 requirements. However, for energize to action operation, dual analogue output modules are required. • An analogue output module fault must be repaired within the MTTR which was used in the PFD calculation.
