UR4CH GE 是一个数字I/O模块 在不同的UR继电器之间传输数据

【产品详情】

GE Multilin的UR-4CH是一个数字I/O模块，允许在不同的UR继电器之间直接、高速地传输数据。数字 I/O 消息传递模块支持实时监控系统通道以及诊断运行状况报告，从而全面查看通道运行状况。

该模块还支持与 20 个或更少的 UR 单元进行通信，允许冗余或单环，而不是基本的点对点配置。该模块通过其内置的诊断功能减少了对辅助测试设备的需求。该模块还提供与标准 D703 通道组的连接。

用户可以通过编辑系统设置来配置直接 I/O 消息传递，无论是使用键盘和 LCD 还是 EnerVista UR 软件程序。更改直接 I/O 数据速率可以调整 I/O 通信的时序，但应注意的是，G.64 模块的速率固定为 1601 kbps。用户还可以调整与振铃配置、报警触发、通道交叉等相关的设置。

参考GE的通用继电器用户手册时，模块更换和安装相对容易，每个手册都有一个关于正确程序的部分。T0090变压器保护系统的2-60-AB<>等手册包含更多信息，可在AX Control的网站上找到。

关于 UR-4CH 的常见问题

UR-4CH与Multilin通用继电器中可能发现的其他数字输入/输出（I / O）模块有什么区别？

UR-4CH 数字 I/O 模块符合“4C”顺序规范。这指定数字 I/O 模块具有 4 个固态 MOSFET 输出（带可选电压的电流）。由于UR-4CH是固态输出数字I/O模块，这意味着它具有快速跳闸时间、快速复位时间和高电流断路能力，是直接跳闸应用的理想选择。这些输出可用于控制和监视变电站辅助设备以及用于保护应用的其他设备。通用继电器Multilin中的数字I/O模块的4A和4B订单选项还具有四个MOSFET输出。三个订货号之间的区别在于4A选项缺乏监控功能，而4B订货选项可以通过可选的电流监控来监控电压。如前所述，4C 阶次选项可以使用附加选项监控电流，以根据特定单元监控电压。其他数字I/O模块可能具有完全不同的特性（A型或C型），或者包含用于温度监控功能的RTD输入。UR 中包含的数字 I/O 特定于通用多林继电器的最终功能和应用。

【英文介绍】

GE Multilin's UR-4CH is a digital I/O module that allows direct, high-speed data transfer between different UR relays. The digital I/O messaging module enables real-time monitoring of system channels and diagnostic health reports for a comprehensive view of channel health.

The module also supports communication with 20 or fewer UR cells, allowing for redundancy or single loops instead of a basic point-to-point configuration. The module reduces the need for auxiliary test equipment through its built-in diagnostic capabilities. The module also provides connectivity to the standard D703 channel group.

Users can configure direct I/O messaging by editing system Settings, whether using the keyboard and LCD or the EnerVista UR software program. Changing the Direct I/O data rate The timing of the I/O communication can be adjusted, but it should be noted that the rate of the G.64 module is fixed at 1601 kbps. Users can also adjust Settings related to ringing configuration, alarm triggering, channel crossing, and more.

Module replacement and installation are relatively easy when referring to GE's Universal Relay user manual, each of which has a section on proper procedures. Manuals such as 2-60-AB<> for the T0090 Transformer Protection system contain more information and can be found on AX Control's website.

Frequently Asked questions about UR-4CH

How does the UR-4CH differ from other digital input/output (I/O) modules you might find in Multilin universal relays?

The UR-4CH digital I/O module complies with the "4C" sequence specification. This specifies a digital I/O module with 4 solid-state MOSFET outputs (current with selectable voltage). Because the UR-4CH is a solid-state output digital I/O module, this means that it has a fast trip time, fast reset time, and high current break capability, making it ideal for direct trip applications. These outputs can be used to control and monitor substation auxiliary equipment and other equipment for protection applications. The 4A and 4B order options for the digital I/O modules in the universal Relay Multilin also feature four MOSFET outputs. The difference between the three order numbers is that the 4A option lacks monitoring, while the 4B order option can monitor voltage with optional current monitoring. As mentioned earlier, the 4C order option can monitor the current with additional options to monitor the voltage based on a specific cell. Other digital I/O modules may have completely different characteristics (type A or Type C) or contain RTD inputs for temperature monitoring functions. The digital I/O included in UR is specific to the final function and application of a general purpose Dorin relay.
