UR9AH GE CPU模块 提供逻辑算法

【产品详情】

通用电气Multilin的UR-9AH是一款CPU模块，用于安装在通用继电器系列中。它通过提供逻辑算法、逻辑门、定时器和锁存器来提供继电保护元件。CPU模块还能够与继电器内的其他模块(如CT/VT模块)连接，帮助确定所述模块收集的参数。需要注意的是，新的CT/VT模块必须与新的CT/VT配套使用，而旧的CT/VT模块必须与旧的CPU模块配套使用。不匹配这些因素的用户将收到来自系统的DSP错误或硬件不匹配。CPU模块不需要接地防雷连接。

有相当大量的CPU模块发布，所以潜在的买家应该仔细阅读万能继电器手册中包含的选项，然后再进行购买。例如，一些CPU模块支持并行冗余协议(PRP)，这是一种以太网网络协议标准，可保证针对任何网络组件的故障进行有效的故障转移。用户应该购买最能满足其特定系统需求的CPU模块。

关于UR-9AH的常见问题

当涉及到Multilin GE系列通用继电器时，UR-9AH是什么类型的模块?它兼容什么固件版本?

UR-9AH被归类为与Multilin GE系列通用继电器一起使用的CPU模块，例如F35馈线保护系统，G60发电机管理继电器或用于网络稳定性和同步量测量的N60。UR(通用继电器)将许多设备集成到一个统一的继电器系统中，以提高最终用户的效率和便利性。UR- 9ah是一种型号的CPU，可以在UR继电器中找到。每个UR继电器还将包含电源、继电器间通信、CT/VT输入、数字输入/输出、传感器输入/输出、通信开关和IEC过程总线。订单规格功能可以在不同的硬件模块和软件选项之间进行选择。UR-9AH是旧型号(9A、9C、9D)的CPU。UR-9AH指定的唯一描述是RS485和RS485 (Modbus RTU, DNP)。符合此特性的较新的CPU模块是9E版本。由于UR- 9ah是旧型号，那么CT/VT也必须是旧版本(8A, 8B, 8C或8D)，例如在UR F35馈线保护系统中。

【英文介绍】

General Electric Multilin’s UR-9AH is a CPU Module intended for installation in the Universal Relay series.  It offers the relay protective elements by supplying it with logic algorithms, logic gates, timers, and latches.  The CPU module is also capable of interfacing with other modules within the relay, such as the CT/VT module, helping determine the parameters collected by said modules.  It should be noted that new CT/VT modules must be used with new CT/VTs while old CT/VT modules must be used with old CPU modules.  Users not matching these factors properly will receive a DSP ERROR or HARDWARE MISMATCH from the system.  CPU modules do not require a ground surge connection.

There is a fairly large amount of CPU modules released, so prospective buyers should carefully read the options contained in the Universal Relays manuals before making a purchase.  Some CPU modules, for example, support Parallel Redundancy Protocol (PRP), an Ethernet network protocol standard that guarantees efficient failover against the failure of any network component.  Users should purchase the CPU module that best serves their specific system needs.

Frequently Asked Questions about UR-9AH

What type of module is a UR-9AH as it relates to the Multilin GE series of universal relays?  What firmware versions is it compatible with?

The UR-9AH is classified as a CPU module for use with the Multilin GE series of universal relays, such as the F35 feeder protection system, the G60 generator management relay, or the N60 for network stability and synchrophasor measurement.  A UR (universal relay) incorporated many of the pieces of equipment into one consolidated relay system for better efficiency and convenience for the end user.  The UR-9AH is one model of CPU that can be found within the UR relays.  Each UR relay will also contain a power supply, an inter-relay communications, a CT/VT input, a digital input/output, a transducer input/output, a communication switch and an IEC Process Bus.  The order specifications function to select among the different hardware modules and software options.  The UR-9AH is a CPU of the older models (9A, 9C, or 9D).   The unique description specified by the UR-9AH is the RS485 and RS485 (Modbus RTU, DNP).  The newer CPU module that matches this characteristic is the 9E version.  Since the UR-9AH is of the older models, then the CT/VT must also be an older version (8A, 8B, 8C, or 8D) within the UR F35 feeder protection system for example.
