760-P5-G5-S5-HI-A20-R电机管理继电器

760-P5-G5-S5-HI-A20-R 是 GE SR 继电器系列中的 GE Multilin 继电器（与 GE Multilin 469 电机保护继电器和 GE Multilin 735 馈线保护继电器属于同一系列。） 专为发电机保护而设计，可用于感应或同步发电机。该装置可以在 25、50 或 60 赫兹下运行。

760-P5-G5-S5-HI-A20-R设计有 40 个字符的显示屏，允许用户查看值消息、诊断和设置点。前面板包括数字键盘、状态指示灯、数值上下键、RS232 端口接口以及控制和编程键，包括复位、输入、菜单、菜单向上和菜单向下键。 这允许在不连接到外部计算机的情况下进行控制。

后面板包括十二个 RTD 输入、六个输出继电器、两个 RS485 通信端口和四个 VT 输入。RTD 是现场可编程的。通信端口可以使用 ModbusRTU 或 DNP 3.0 协议（或两者），最高可达 19200 bps。

760-P5-G5-S5-HI-A20-R的后面板还包括四个隔离的 4-20 mA 模拟输入和输出以及七个可分配的数字输入。有七个 CT 输入用于三相输出/三相中性线和接地电流检测，以及一个单独的安全和滤波器接地。 SR489-P5-HI-A20-E上的所有输入均符合 SWC、C37.990 EMI、RFI 抗干扰性。

The 760-P5-G5-S5-HI-A20-R is a GE Multilin relay in the GE SR relay family (in the same family as the GE Multilin 469 motor protection relay and the GE Multilin 735 feeder protection relay). Designed for generator protection, it can be used in induction or synchronous generators. The device can operate at 25, 50 or 60 Hertz.

The 760-P5-G5-S5-HI-A20-R is designed with a 40-character display that allows users to view value messages, diagnostics, and setting points. The front panel includes a numeric keypad, status indicators, numerical up and down keys, RS232 port interfaces, and control and programming keys, including reset, input, menu, menu Up, and menu Down keys. This allows control without being connected to an external computer.

The rear panel includes twelve RTD inputs, six output relays, two RS485 communication ports, and four VT inputs. RTDS are field programmable. Communication ports can use ModbusRTU or DNP 3.0 protocols (or both) up to 19200 bps.

The 760-P5-G5-S5-HI-A20-R's rear panel also includes four isolated 4-20 mA analog inputs and outputs and seven assignable digital inputs. There are seven CT inputs for three-phase output/three-phase neutral line and ground current detection, as well as a separate safety and filter ground. All inputs on the SR489-P5-HI-A20-E comply with SWC, C37.990 EMI, RFI anti-interference.
