产品描述

269-10C-120是GE制造的Multilin系列中的电机管理继电器。269-10C-120 使用定子 RTD 温度读数和电机相电流读数来模拟其保护的电机。269-10C-120 监控机械负载和电机是否存在问题。使用可选的GE多林表（MPM），该模块还可以跟踪功率和电压，并根据这些值执行任务。

269-10C-120 包括以下标准功能：

微电脑控制

通过键盘现场编程

48 个字符的字母数字显示

内置“帮助”功能

继电器电路内置自检功能

紧急重启功能

行车前警报警告

269-10C-120 可用于各种设置，包括保护泵、齿轮和风扇。它可以保护压缩机免受过载。利用暗流功能，269-10C-120 可以保护泵免受吸入损失和风扇免受气流损失。269-10C-120 还可以保护设备和电机免受操作员滥用，并保护最终用户免受湿气接地泄漏电流造成的电击危险。

269-10C-120 的前面板包括一个用于查看数据的 48 个字符的背光 LCD 显示屏、4 个显示输出继电器何时运行的 LED、1 个指示自检报警何时跳闸的 LED，以及一个用于选择实际值、编程设定值以及指示报警和跳闸原因的键盘。

建议用户使用 269 个垫圈和 10 个 120-4 x 4/10“ 安装螺钉安装 32-3C-8。尽管内部组件已被屏蔽，但继电器应安装在不会受到大电流导体强磁场影响的地方。

Product description

The 269-10C-120 is a motor management relay in the Multilin family manufactured by GE. The 269-10C-120 uses stator RTD temperature readings and motor phase current readings to simulate the motor it protects. 269-10C-120 Monitors mechanical loads and motors for problems. Using an optional GE Dohling meter (MPM), the module can also track power and voltage and perform tasks based on these values.

The 269-10C-120 includes the following standard features:

Microcomputer control

Live programming via keyboard

48-character alphanumeric display

Built-in Help function

Relay circuit built-in self-test function

Emergency restart function

Pre-train alarm warning

The 269-10C-120 can be used in a variety of Settings, including protective pumps, gears, and fans. It protects the compressor from overload. With the undercurrent function, the 269-10C-120 protects the pump from suction losses and the fan from airflow losses. The 269-10C-120 also protects equipment and motors from operator abuse and protects end users from the danger of electric shock caused by wet ground leakage currents.

The 269-10C-120's front panel includes a 48-character backlit LCD display for viewing data, four leds to show when the output relay is running, one LED to indicate when the self-test alarm is tripping, and a keyboard to select actual values, program setpoints, and indicate the cause of alarm and tripping.

It is recommended that the user install the 32-3C-8 using 269 washers and 10 120-4 x 4/10 "mounting screws. Although the internal components have been shielded, the relay should be installed where it will not be affected by the strong magnetic field of the high-current conductor.
