产品描述

继电器489- p5 - lo - a20 - t是489发电机管理继电器系列中为数不多的型号之一，该系列配备了带有10Base-T以太网连接的增强型显示器。由于它是为数不多的这种连接类型之一，有特殊的布线规范。请注意，当此继电器安装在机箱中并且必须拆除时，必须断开设备上的RJ45连接器，以防止发生任何损坏。当您将继电器插入机箱时，请小心，并确保以太网电缆有足够的空间，以便在将继电器滑回机箱时不会被捕获。如果电缆被抓住，它不仅可以损坏电缆，而且干扰正确插入的情况下端子块。

489-P5-LO-A20-T继电器上有各种各样的端子类型。一些端子及其描述如下，G10 HGF接地CT, D02 RTD #7补偿，E01 1行程NC, F12 IRIG-B -等等。与此继电器相关的所有终端的完整综合列表可在GEH-10649N 489发电机使用手册的第三章第8页找到。所有的一般接线注意事项，控制电源规格，电流输入，以及它们的用途可以在本手册的第三章中找到。

当看这个继电器的面板时，请注意有三组不同的LED指示灯。489- p5 - lo - a20 - t继电器上的三组分别是489型号的状态、输出状态和所连接发电机的状态。所有led及其功能的综合清单将在上述手册的第四章4.1.2标题下找到。

Product description

The Relay 489-P5-LO-A20-T is one of the few models in the 489 generator management relay family, which is equipped with an enhanced display with 10Base-T Ethernet connectivity. Since it is one of the few such connection types, there are special wiring specifications. Note that when this relay is installed in the case and must be removed, the RJ45 connector on the device must be disconnected to prevent any damage from occurring. Be careful when you plug the relay into the case, and make sure the Ethernet cable has enough space so that it won't get caught when sliding the relay back into the case. If the cable is caught, it can not only damage the cable, but also interfere with the terminal block in case of proper insertion.

A wide variety of terminal types are available on 489-P5-LO-A20-T relays. Some terminals and their descriptions are as follows, G10 HGF grounded CT, D02 RTD #7 compensation, E01 1 stroke NC, F12 IRIG-B - and so on. A complete comprehensive list of all terminals associated with this relay can be found on page 8 of Chapter 3 of the GEH-10649N 489 Generator Operator's Manual. All general wiring considerations, control power supply specifications, current inputs, and their purpose can be found in Chapter 3 of this manual.

When looking at the panel of this relay, notice that there are three different sets of LED indicators. The three groups on the 489-P5-LO-A20-T relay are the status of model 489, the output status, and the status of the connected generator. A comprehensive list of all leds and their features will be found under the heading 4.1.2 of Chapter IV of the above manual.
