1756-RM A 是 ControlLogix 增强型冗余模块

Allen-Bradley 1756-RM 是一款 ControlLogix 冗余模块。此模块只能与 ControlLogix 平台一起使用，以启用控制器冗余。它管理两 （2） 个相同控制器的连接，这些控制器安装在具有相同组件和配置的相同机架中。它通过嵌入式 LED 显示屏（如 PRI、COM 和 OK）提供冗余系统监控以及模块运行状况。 1756-RM 已作为 A 系列和 B 系列发布。 系列基本上是先前系列的增强版，但是，具有不同系列的 1756-RM 可以在一个冗余配置中共存。

强烈建议安装相同的系列，以实现冗余设置的最大可操作性。当与同系列冗余模块一起使用时，速度可达 100 Mbps。

1756-RM 配有一 （1） 个单模 LC 光纤连接器。它需要使用 1756-RMCx 冗余电缆来同步冗余控制器对的操作。可以使用冗余配置工具配置此控制器来设置冗余，并使用 Studio 5000 Logix 设计器来配置模块的整体参数。

该模块兼容 1756-A4、1756-A7、1756-A10、1756-A13、1756-A17 ControlLogix 机箱、1756-PA72、1756-PA75、1756-PB72、1756-PB75 标准电源和 1756-PA75R、1756-PB75R、1756-PSCA2 冗余电源。它是一个单插槽模块，可以安装到机箱中的任何可用插槽中。冗余对必须具有与伙伴机箱相同的配置。

1756-RM 在 4.1VDC 时的电流消耗为 2 mA，在 1.2VDC 时为 5.1 mA，在 120VDC 工作时为 24 mA。

1756-RM 冗余模块在 4.1 伏直流电下的电流消耗为 2 毫安，在 1.2 伏直流电下为 5.1 毫安，在 120 伏直流电下为 24 毫安。该装置安装在机箱中，可以安装在任何插槽中。1756-RM 模块的功耗为 9 瓦，散热为每小时 31 BTU。该 ControlLogix 带有开放式外壳，并带有 T4 温度代码。关于模块的物理特性，它的重量约为 0.29 公斤或 0.64 磅，并且尺寸小。1756-RM 模块的工作温度范围为 0 至 60 摄氏度（32 至 140 华氏度），可存放在 -40 至 85 摄氏度（-40 至 185 华氏度）的温度范围内。该装置是根据多项工业标准制造的，包括 CE、CSA、Ex、C-Tick 和 c-UL-us 标准的认证。

1756-RM A 是 ControlLogix 增强型冗余模块

The Allen-Bradley 1756-RM is a ControlLogix redundant module. This module can only be used with the ControlLogix platform to enable controller redundancy. It manages the connection of two (2) identical controllers installed in the same rack with the same components and configuration. It provides redundant system monitoring and module health through embedded LED displays such as PRI, COM and OK. The 1756-RM has been released as Series A and Series B. The series is basically an enhanced version of the previous series, however, the 1756-RM with different series can coexist in a redundant configuration.

It is highly recommended to install the same series for maximum operability of redundant Settings. When used with the same series of redundant modules, the speed can reach 100 Mbps.

The 1756-RM is equipped with one (1) single-mode LC fiber optic connector. It requires the use of 1756-RMCx redundant cables to synchronize the operation of redundant controller pairs. This controller can be configured using the Redundancy Configuration tool to set redundancy and the Studio 5000 Logix Designer to configure the overall parameters of the module.

This module is compatible with 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17 ControlLogix chassis, 1756-PA72, 1756-PA75, 1756-PB72, 1756-PB75 standard power supplies and 1756-PA75R, 1756-PB75R, 1756-PSCA2 Redundant power supply. It is a single slot module that can be installed into any available slot in the case. The redundancy pair must have the same configuration as the partner chassis.

The 1756-RM has a current consumption of 2 mA at 4.1VDC, 5.1 mA at 1.2VDC, and 24 mA at 120VDC.

The 1756-RM redundancy module has a current consumption of 2 mA at 4.1 volts DC, 5.1 MA at 1.2 volts DC, and 24 MA at 120 volts DC. The device is installed in the case and can be installed in any slot. The 1756-RM module has a power consumption of 9 watts and a heat dissipation of 31 BTU per hour. The ControlLogix comes with an open housing and comes with a T4 temperature code. Regarding the physical characteristics of the module, it weighs about 0.29 kg or 0.64 LBS and is small in size. The 1756-RM module operates in a temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and can be stored in a temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The unit is manufactured according to a number of industry standards, including CE, CSA, Ex, C-Tick and c-UL-us standards.
