MMII-PD-1-2-240 控制模块 电机系统控制器

【产品详情】

通用电气Multilin电机管理器是一系列控制模块，结合了多种功能，用于控制电机功能和提供电机保护。该产品最初由通用电气的工业自动化部门开发和生产。与其他品牌和型号的分立式电机控制器相比，电机管理器II（也称为MM2）是一种旨在以尽可能低的价格提供最复杂控制和保护的设备。

该型号的电机管理器II系列MMII-PD-1-2-240旨在涵盖低压电机控制旨在处理的大量功能，例如处理任何可能的过载，不平衡的相位，可能的承包商故障以及转子锁定和/或失速。该型号还集成了一个热绕组热敏电阻模块。如果继电器检测到功率低于所需的标称摄入量，则欠压自动重启启动。这些功能可保护电机系统并延长系统寿命。

MMII-PD-1-2-240 单元的物理框架配备了一组 4 个输出端口和 16 个输入端口。输出端口被指定为一对承包商输出和一对可编程输出。对于输入端口，有 6 个固定输入和 10 个可编程输入。

对于信息报告，该装置配备了一个模拟接口，显示相电流、接地电流、热容量模拟输入以及功率和能量水平。该模型确保记录行程并记录相应的行程前值进行比较。

该装置可以与 RS485 ModBus Plus 模块集成，速度为每秒 1200 至 19200 位 （bps）。

有关 MMII-PD-1-2-240 的常见问题

MMII-PD-1-2-240的产品说明中的“PD”指的是什么？它与其他型号有何不同？

型号中的“PD”表示该装置提供带显示屏的面板安装。该显示器是一个两行、四十个字符的液晶显示器，可与键盘配合使用，以手动导航系统设置、参数、事件日志等。带有“C”而不是“PD”的选项根本不提供液晶显示器，而是要求用户使用 EnerVista MMII 软件来微调设备。

MMII-PD-1-2-240 有哪些选件包？它们是否包含在此模型中？

两个选件包都包含在此版本的零件中，由型号中的“1”和“2”表示;在没有这些选项的零件版本中，这些将替换为零。选项 1 包括 10 个可编程开关输入、一个 4 至 20 mA 输入和 2 个附加机电继电器。它还包括欠压重启选项和高级诊断。选件 2 为继电器提供定时器、接触器 A 和 B 继电器以及 2 个开关输入。它还提供增强的保护、用于计算 kW 和 kWhrs 的 VT 输入以及热敏电阻输入。

【英文介绍】

The General Electric Multilin Motor Manager is a family of control modules that combine multiple functions to control motor function and provide motor protection. The product was originally developed and produced by GE's Industrial automation division. Compared to other brands and models of discrete motor controllers, the Motor Manager II (also known as MM2) is a device designed to provide the most sophisticated control and protection at the lowest possible price.

This model of motor manager, Series II MMI-PD-1-2-240, is designed to cover a large number of functions that low-voltage motor control is designed to handle, such as handling any possible overloads, unbalanced phases, possible contractor failures, and rotor locking and/or stalling. This model also incorporates a thermal winding thermistor module. If the relay detects that the power is below the required nominal intake, the undervoltage restarts automatically to start. These features protect motor systems and extend system life.

The physical frame of the MMI-PD-1-2-240 unit is equipped with a set of 4 output ports and 16 input ports. The output ports are specified as a pair of contractor outputs and a pair of programmable outputs. For input ports, there are 6 fixed inputs and 10 programmable inputs.

For information reporting, the unit is equipped with an analog interface that displays phase current, ground current, heat capacity analog inputs, and power and energy levels. The model ensures that trips are recorded and corresponding pre-trip values are recorded for comparison.

The unit can be integrated with the RS485 ModBus Plus module at speeds of 1200 to 19,200 bits per second (bps).

Frequently Asked Questions about MII-PD-1-2-240

What does "PD" refer to in the product description of MMII-PD-1-2-240? How does it differ from other models?

The "PD" in the model number indicates that the device offers panel mounting with a display. The display is a two-line, 40-character LCD that can be used in conjunction with a keyboard to manually navigate system Settings, parameters, event logs, and more. The option with "C" instead of "PD" does not provide an LCD display at all, but instead requires the user to fine-tune the device using EnerVista MMII software.

What package options are available for MMII-PD-1-2-240? Are they included in this model?

Both option packages are included in this version of the part, represented by the "1" and "2" in the model number; In parts versions without these options, these will be replaced with zeros. Option 1 includes 10 programmable switching inputs, a 4 to 20 mA input, and two additional electromechanical relays. It also includes undervoltage restart options and advanced diagnostics. Option 2 provides timers, contactor A and B relays, and 2 switching inputs for the relay. It also provides enhanced protection, VT inputs for calculating kW and kWhrs, and thermistor inputs.
