TRICONEX PLM 3900N 优先控制模块 它的主要功能是在对来自不同安全等级的自动或手动指令进行优先排序后

PLM 3900N优先控制模块是核电站安全级仪表和控制平台的一个组成部分。它的主要功能是在对来自不同安全等级的自动或手动指令进行优先排序后，驱动专用安全设施和相关支持系统中的泵、阀[ ]和其他设备。位于执行端的执行器(如阀门、掠电机等)需要根据系统的驱动信号执行相应的功能。执行器的驱动信号可以由几个系统给出。为了防止信号之间的冲突导致不正常的执行，优先控制模块需要判断这些信号,并确保执行器根据正确的信号执行。

The PLM 3900N priority control module is a component of the safety level instrument and control platform for nuclear power plants. Its main function is to drive pumps, valves, and other equipment in specialized safety facilities and related support systems after prioritizing automatic or manual commands from different safety levels. The actuators located at the execution end (such as valves, sweep motors, etc.) need to perform corresponding functions based on the drive signal of the system. The driving signal of the actuator can be provided by several systems. In order to prevent conflicts between signals from causing abnormal execution, the priority control module needs to judge these signals and ensure that the actuator executes according to the correct signal.
