UR7QH 通信模块 为UR单元提供两个通道

【产品详情】

通用电气Multilin的UR-7QH是一个通信模块，为通用继电器单元提供两个通道：一个通道是G.703模式通道，另一个是1300 nm单模激光通道。单模光纤在长距离上的衰减比多模线路要小，这使得该型号成为用户远距离布线的绝佳选择。

该继电器还包括不对称补偿功能，允许继电器校正长达 1ms 的通道不对称。继电器能够提供有关通道运行状况的诊断，并在 EnerVista UR 中显示数据。继电器可以通过触发警报来提醒用户通道故障，使用户能够采取措施解决通道问题。 

关于 UR-7QH 的常见问题

UR 系列通用多林继电器的通信模块 UR-7QH 的通道名称是什么？

UR-7QH 是各种 UR 系列多林 GE 通用继电器中的通信模块，增加了通用继电器的综合性。UR-7QH 的订单名称为 7Q，如此特定 COMMS 模块的型号中所述。7Q 订单选项是一个双通道 COMMS 模块。第一个通道（通道 1）指定为 G.703。G.703 是一个相当标准的通道，可以根据设备的不同，以各种数据速率提供脉冲编码调制规格 （PCM）。它通过平衡（双绞 120 欧姆对）或非平衡（双同轴 75 欧姆）电缆传输。G.703可以通过T1或E1等载波发送通信。UR-7QH具有第二个通道（通道2），该通道被描述为1300 nm波长的单模激光器，用于传输通信信号。每个通道都有利于 UR-7QH 用作 Multilin UR 系列通用继电器中的通信模块。COMMS 模块具有多达六种环路定时模式和多达六种内部定时模式，这些模式通常是出厂预设的。

【英文介绍】

Ge Multilin's UR-7QH is a communication module that provides two channels for the universal relay unit: one channel is a G.703 mode channel and the other is a 1300 nm single-mode laser channel. Single-mode fibers have less attenuation over long distances than multimode lines, making this model an excellent choice for users to route over long distances.

The relay also includes asymmetry compensation, which allows the relay to correct channel asymmetries up to 1ms. The relay provides diagnostics about the health of the channel and displays the data in the EnerVista UR. Relays can alert users to channel failures by triggering alarms, enabling users to take action to resolve channel problems.

Frequently Asked Questions about UR-7QH

What is the channel name of UR-7QH communication module of UR series general Dorin relay?

Ur-7qh is a communication module in various UR series Dorin GE universal relays, which increases the comprehensives of universal relays. The order name for UR-7QH is 7Q, as described in the model number of the specific COMMS module. The 7Q order option is a dual-channel COMMS module. The first channel (channel 1) is designated G.703. G.703 is a fairly standard channel that can provide pulse code modulation specifications (PCM) at a variety of data rates depending on the device. It is transmitted via a balanced (120 ohm pair in twisted pairs) or unbalanced (double coaxial 75 ohm) cable. The G.703 can send communications via a carrier such as T1 or E1. UR-7QH has a second channel (channel 2), which is described as a single mode laser with a wavelength of 1300 nm for transmitting communication signals. Each channel facilitates UR-7QH as a communication module in the Multilin UR series of universal relays. COMMS modules have up to six loop timing modes and up to six internal timing modes, which are usually factory preset.
