1757-SRM  机箱  适用于62.5/125微米SC型多模光纤

描述:艾伦-布拉德利1757-SRM是一个ProcessLogix和ControlLogix系统冗余模块。该模块通过与另一个ControlLogix机箱的另一个1756-SRM配对来实现控制器冗余。本模块为2插槽模块，集成光纤接口，适用于62.5/125微米SC型多模光纤。

1757-SRM 机箱作为电脑配件中的一部分，其主要作用是放置和固定各电脑配件，起到一个承托和保护作用。此外，电脑机箱还具有屏蔽电磁辐射的重要作用。虽然在DIY中并不是很关键的配置，但是使用质量不良的机箱容易让主板和机箱短路，导致电脑系统变得不稳定。

1757-SRM 机箱一般包括外壳、支架、面板上的各种开关、指示灯等。外壳用钢板和塑料结合制成，硬度高，主要起保护机箱内部元件的作用；支架主要用于固定主板、电源和各种驱动器。此外，机箱也有多种类型，例如AT、ATX、Micro ATX以及最新的BTX等。

在选购机箱时，需要注意以下几点：

机箱的尺寸：需要能够容纳所有的电脑配件，并且留有一定的空间以便散热和维护。

机箱的质量：优质的机箱能够有效防止电磁辐射外泄，保护用户的健康。

机箱的散热性能：对于电脑的稳定运行来说，良好的散热非常重要。因此，在选购机箱时需要考虑其散热性能，如是否有足够的散热孔和风扇位等。

机箱的功能：不同的机箱可能具有不同的功能，例如支持多路显卡、支持超长电源等。根据用户的需求选择合适的机箱。

总之，1757-SRM 机箱虽然不是电脑性能的关键因素，但对于电脑的稳定运行和用户的健康来说非常重要。在选购机箱时需要仔细考虑以上因素，选择适合自己的优质机箱。

Description: The Allen Bradley 1757-SRM is a redundant module for ProcessLogix and ControlLogix systems. This module enables controller redundancy by pairing with another 1756-SRM in another ControlLogix chassis. This module is a 2-slot module with integrated optical fiber interfaces and applies to 62.5/125 micron SC multi-mode optical fibers.

1757-SRM chassis as a part of the computer accessories, its main role is to place and fix the computer accessories, play a supporting and protective role. In addition, the computer case also has an important role in shielding electromagnetic radiation. Although it is not a critical configuration in DIY, the use of poor quality chassis is easy to short-circuit the motherboard and chassis, resulting in unstable computer systems.

The 1757-SRM chassis generally includes a shell, bracket, various switches and indicators on the panel. The shell is made of steel plate and plastic, with high hardness, mainly to protect the internal components of the chassis; The bracket is mainly used to fix the motherboard, power supply and various drives. In addition, there are many types of chassis, such as AT, ATX, Micro ATX, and the latest BTX.

When purchasing a chassis, the following points need to be noted:

The size of the case: It needs to be able to accommodate all the computer accessories, and leave some space for heat dissipation and maintenance.

The quality of the chassis: A high-quality chassis can effectively prevent electromagnetic radiation leakage and protect the health of users.

Heat dissipation performance of the chassis: Good heat dissipation is very important for the stable operation of the computer. Therefore, when purchasing a chassis, you need to consider its heat dissipation performance, such as whether there are enough heat dissipation holes and fan slots.

Chassis functions: Different chassis may have different functions, such as support for multiple graphics cards, support for ultra-long power supplies, and so on. Select the appropriate chassis according to the user's requirements.

In summary, the 1757-SRM chassis is not a critical factor in computer performance, but it is very important for the stable operation of the computer and the health of the user. When purchasing a chassis, you need to carefully consider the above factors and choose a high-quality chassis that suits you.
