产品描述

SR489-P5-HI-A20是GE Multilin为489系列制造的发电机管理继电器。这个继电器有5个A相CT次级。HI控制电源为90-300 VDC, 70265 VAC, 48-62 Hz。该继电器上的模拟输出为4至20 mA。这个继电器有一个基本的显示。当继电器通电时，继电器触点不安全。如果输出继电器触点需要用于低压可及应用，则客户有责任确保适当的绝缘水平。保险丝额定电流为2.5 A。保险丝型号为5x20mm HRC slow - blo Littelfuse，保险丝型号为215-02.5。

该系列的订单代码告诉用户有关该部件的一些详细信息。489表示这部分来自的系列。接下来的两位数字是相电流输入，P1 (1a相CT二次)或P5 (5a相CT二次)。后面两位数字为控制电源，为LO (20 ~ 60vdc, 20 ~ 48vac, 48 ~ 62hz)或HI (90 ~ 300vdc, 70 ~ 265 VAC, 48 ~ 62hz)。后面的两位或三位数字为模拟输出，A1 (0 ~ 1ma模拟输出)或A20 (4 ~ 20ma模拟输出)。下一个数字是显示，它要么是空白(基本显示)，E(带有更大LCD的增强显示)，要么T(带有以太网10Base-T的增强显示)。下一位为恶劣环境保护，其中H为化学环境适形涂层。

Product description

The SR489-P5-HI-A20 is a generator management relay manufactured by GE Multilin for the 489 series. This relay has 5 A phase CT secondary. HI control power supply is 90-300 VDC, 70265 VAC, 48-62 Hz. The analog output on this relay is 4 to 20 mA. This relay has a basic display. When the relay is powered on, the relay contact is not safe. If the output relay contacts are required for low voltage access applications, it is the customer's responsibility to ensure appropriate insulation levels. The fuse is rated at 2.5 A. The fuse model is 5x20mm HRC slow-blo Littelfuse and the fuse model is 215-02.5.

The order code for the series tells the user some details about the part. 489 indicates the series from which this part comes. The next two digits are the phase current input, P1 (1a phase CT quadratic) or P5 (5a phase CT quadratic). The last two digits are the control power supply, which is LO (20 ~ 60vdc, 20 ~ 48vac, 48 ~ 62hz) or HI (90 ~ 300vdc, 70 ~ 265 VAC, 48 ~ 62hz). The next two or three digits are analog outputs, A1 (0 to 1ma analog output) or A20 (4 to 20ma analog output). The next number is the display, which is either blank (basic display), E(enhanced display with a larger LCD), or T(enhanced display with Ethernet 10Base-T). Next is harsh environment protection, where H is the chemical environment conformal coating.
