描述：ABB P4LR 1KHL015107R0001 PLC模块

重要的双回路线路（132 kV 至 400 kV）通常在每个回路上配备重复的线路保护和断路器故障保护。然后将两个ETL500 链路（每个链路都带有一个四命令 NSD550）排列在冗余远程保护方案中（操作模式“2+2”）。重要的单回路线路（400 kV 至 800 kV）始终配备重复的主保护、断路器故障保护，也许还有发电机停机/减载设施。然后将两个 ETL500链路（每个链路都带有一个四命令NSD550）排列在完全复制的远程保护方案中（操作模式“2+2”）。带有四个命令的 NSD550 也可用于三相线路的隔相保护（工作模式“3+1”）。

功能（可能性）：

工业通信板：这是一种常见的可能性。它可以使用Profibus、Modbus或CANopen等协议实现控制系统内各种工业设备之间的通信。

驱动控制器板：在某些情况下，P4LR板可能与ABB的驱动系统相关联，可能控制变速驱动器以调节电机速度。

具体应用板：该电路板有可能是为特定行业或机器类型中的特定ABB应用而设计的。

Description: ABB P4LR 1KHL015107R0001 PLC module

Important dual circuit routes (132 kV to 400 kV) are typically equipped with repeated line protection and circuit breaker failure protection on each circuit. Two ETL500 links (each with a four-command NSD550) are then arranged in a redundant remote protection scheme (operating mode "2+2"). Critical single-loop lines (400 kV to 800 kV) are always equipped with repeated main protection, circuit breaker failure protection, and perhaps generator shutdown/load shedding facilities. Two ETL500 links (each with a four-command NSD550) are then lined up in a fully replicated remote protection scheme (operating mode "2+2"). The NSD550 with four commands can also be used for phase isolation protection of three-phase lines (operating mode "3+1").

Function (possibility) :

Industrial communication board: This is a common possibility. It can use protocols such as Profibus, Modbus or CANopen to achieve communication between various industrial equipment within the control system.

Drive controller board: In some cases, the P4LR board may be associated with ABB's drive system and may control variable speed drives to regulate motor speed.

Application Board: The board may be designed for a specific ABB application in a specific industry or machine type.
