UR7HH 通信模块 提供中继间通信功能 GE 

【产品详情】

UR-7HH 通信模块提供两个中继间通信通道，旨在安装在通用继电器系列中。该模块为继电器提供两个多模 LED 通道，工作波长为 820 nm。

虽然多模光纤布线比单模布线便宜得多，但多模设置的长距离衰减（或信号损失/dB损失）大于单模。用户在确定购买哪个模块之前应考虑电缆长度;有关不同可用模块选项的更多信息，请参阅通用继电器手册。此外，这些模块以各种波长工作，这也会影响远距离的光散射。潜在买家在购买组件之前应进行适当的研究。

通用继电器系列能够显示模块活动产生的数据，并通过位于设备面板上的 LED 被动地向用户显示，或者通过连接到运行 Multilin's EnerVista 软件程序的继电器的计算机更有效地显示给用户。EnerVista 软件程序提供了一个简化的用户界面，用于监控通道运行状况以及与正在进行的中继间通信相关的趋势和导出数据。EnerVista UR 的硬件要求非常轻，使程序的实施既方便又便宜。

【英文介绍】

The UR-7HH communication module provides communication channels between two relays and is designed to be installed in the general purpose relay family. The module provides two multi-mode LED channels for the relay, operating at 820 nm.

Although multimode fiber cabling is much cheaper than single-mode cabling, the long distance attenuation (or signal loss /dB loss) of a multimode setup is greater than that of a single mode. Users should consider cable length before deciding which module to buy; For more information about the different module options available, see the General Relay manual. In addition, these modules operate at a variety of wavelengths, which also affects light scattering at long distances. Potential buyers should conduct proper research before purchasing components.

The universal relay family is able to display the data generated by module activity and display it to the user passively via leds located on the device panel, or more efficiently via a computer connected to a relay running Multilin's EnerVista software program. The EnerVista software program provides a simplified user interface for monitoring channel health as well as trending and exported data related to ongoing inter-relay communication. The hardware requirements of EnerVista UR are very light, making the implementation of the program convenient and inexpensive.

Frequently Asked questions about UR-7HH

What are the characteristics of UR-7HH?

Ur-7hh is a communication module for UR series Dolin universal relay system. The UR-7HH's inter-relay communication features include an 820 nm multi-mode LED with 2 channels. Each universal relay has high-speed communication capabilities with communication switches, IEC process buses, and relay to relay communication. The communication capability enables Multilin universal relays to be seamlessly integrated into existing systems or infrastructure. There are three Ethernet ports that can be used to handle busy Internet traffic conditions and reduce any potential latency impact. The updated communication feature is IEC 60870 DNP 5.104 with Modbus TCP/IP and the IEC 61850-3-0 protocol. There are also IEEE C37.118 synchronous phasors and Ethernet connections.

What is the size of UR-7HH?

Ur-7hh is a communication module that is one of the many components in the UR series of Doling universal relay systems. The universal relay also contains a CPU, a CT/VT module, an I/O sensor module, a communication switch, and other components that enable the universal relay to serve as an integrated technical solution for the end user. The horizontal UR relay measures 18.974 x 6.960 and is advertised as a 19-inch relay.
