产品描述

269PLUS-DO-211-100P-120VAC是一种电机继电器系统，是GE Multilin分销的269 Plus电机管理继电器系列的一部分。该电机继电器系统的目的是为三相电机系统提供保护，因为它们的功能接近其工作极限。该装置使用电流互感器来监控电机的电气特性。

该驱动器使用 3 欧姆铂电阻热探测器 （RTD） 进行温度监控。驱动器的主要功能包括但不限于自定义曲线可选性、电机统计记录、速度开关输入、差分继电器输入、100 个 RTD 输入、单次紧急重启功能、RS10 通信端口、热存储器不平衡输入、启动抑制功能和备用输入。

电机继电器系统上有四个主输出继电器。主跳闸继电器控制外部设备的电源。还有两个辅助继电器和一个主继电器，设计用于与外部设备通信。这些输出可以编程为具有锁存或非锁存配置。电机继电器系统还具有模拟输出，旨在能够传达电机电流、最热定子 RTD 值、轴承 RTD 或 CT 次级电流等信息。系统的前面板具有用于用户交互的各种指示器。它包含一个 48 个字符的字母数字 LCD 显示屏，用于显示当前值、警报和编程等关键信息。此外，显示屏共有五个 LED 指示灯。前四个对应于继电器输出条件。第五个 LED 对应于自检报警条件。

Product description

The 269PLUS-DO-211-100P-120VAC is a motor relay system that is part of the 269 Plus motor management relay family distributed by GE Multilin. The purpose of this motor relay system is to provide protection for three-phase motor systems as they function close to their operating limits. The device uses a current transformer to monitor the electrical characteristics of the motor.

The driver uses a 3 ohplatin resistance thermal detector (RTD) for temperature monitoring. The main features of the drive include, but are not limited to, custom curve selectivity, motor statistics recording, speed switch input, differential relay input, 100 RTD input, single emergency restart function, RS10 communication port, hot memory unbalanced input, start suppression function, and backup input.

There are four main output relays on the motor relay system. The main trip relay controls the power supply to external devices. There are also two secondary relays and one primary relay, designed to communicate with external devices. These outputs can be programmed to have latched or non-latched configurations. The motor relay system also has analog outputs designed to convey information such as the motor current, the hottest stator RTD value, the bearing RTD or CT secondary current. The front panel of the system has various indicators for user interaction. It contains a 48-character alphanumeric LCD display for key information such as current values, alerts, and programming. In addition, the display has five LED indicators. The first four correspond to relay output conditions. The fifth LED corresponds to the self-check alarm condition.
