UR81H 过程总线模块 提供八端口数字过程总线

【产品详情】

通用电气 Mutlilin的UR-81H是一个过程总线模块，为安装其的通用继电器单元提供八端口数字过程总线。 与大多数模块不同，81-H 是 UR 系列唯一可用的过程总线模块，而不是具有不同通道和功能的大量版本。

过程总线是一种通信网络，允许继电器与电流互感器、断路器、电压互感器和隔离开关等系统设备连接。过程总线可以接收和数字化设备记录的值，允许用户在系统过程中处理更多有形数据。传输的数据格式受IEC标准的约束，这些标准旨在为用户提供更通用的数据格式以供解析。

用户可以通过检查型号来检查其当前系统是否已具有此模块。包括“FXX”或“HXX”的型号不提供八端口数字过程总线，而带有“81”的模块已经包含该功能，在这种情况下，最终不需要购买此模块。

关于 UR-81H 的常见问题

Multilin通用继电器中的CT/VT模块的功能是什么？

CT/VT 模块只是构成 Multilin GE UR 系列通用继电器的众多组件之一。这些通用继电器可以采用 19 英寸水平安装，其中每个组件在继电器上以垂直尺寸排列，也可以采用垂直安装继电器，其尺寸为水平继电器的四分之三。在此安装座中，组件垂直排列。无论哪种情况，通用继电器中的一些组件都是CPU，CT / VT模块，I / O传感器和电源。这些通用继电器还包含一个数字输入输出组件和一个继电器间通信容量。这些组件中的每一个都有助于通用继电器的指定用途，UR 模块设计为 I/O 逻辑控制器 （C30）、断路器控制器 （C60）、提供多个馈线保护或电容器组保护的单元（F35 或 C70），或具有 Hi-Z 故障检测的馈线保护继电器 （F60）。无论主要功能如何，CT/VT 模块都用于为通用继电器提供多达 24 个模拟电压互感器信号和模拟电流互感器信号，以监控交流电源线。

【英文介绍】

General Electric Mutlilin's UR-81H is a process bus module that provides an eight-port digital process bus for the universal relay unit on which it is installed. Unlike most modules, 81-H is the only process bus module available in the UR series, rather than a large number of versions with different channels and functions.

A process bus is a communication network that allows relays to connect to system devices such as current transformers, circuit breakers, voltage transformers, and isolation switches. The process bus can receive and digitize the values recorded by the device, allowing the user to process more tangible data during the system process. The transmitted data format is governed by IEC standards, which are intended to provide users with a more general data format for parsing.

Users can check whether their current system already has this module by checking the model number. Models that include "FXX" or "HXX" do not offer an eight-port digital process bus, while modules with "81" already include this feature, in which case it is ultimately not necessary to purchase this module.

Frequently asked questions about UR-81H

What is the function of the CT/VT module in Multilin universal relays?

The CT/VT module is just one of the many components that make up the Multilin GE UR series of universal relays. These general purpose relays can be mounted in 19-inch horizontally, where each component is arranged in vertical dimensions on the relay, or in vertically mounted relays that are three-quarters the size of the horizontal relays. In this mount, the components are arranged vertically. In either case, some of the components in a universal relay are the CPU, CT/VT module, I/O sensor, and power supply. These general purpose relays also contain a digital input/output component and an inter-relay communication capacity. Each of these components contributes to the specified purpose of a universal relay, and UR modules are designed as I/O logic controllers (C30), circuit breaker controllers (C60), units that provide multiple feeder protection or capacitor bank protection (F35 or C70), or feeder protection relays with Hi-Z fault detection (F60). Regardless of the primary function, CT/VT modules are used to provide up to 24 analog voltage transformer signals and analog current transformer signals for general purpose relays to monitor AC power lines.
