Allen-Bradley 1756-RM/A ControlLogix 增强型冗余模块
【产品详情】
Allen-Bradley 1756-RM 是一种 ControlLogix 增强型冗余模块。它是用于实现控制器冗余的可编程自动化控制器 (PAC) 的一部分。它带有一 (1) 个 LC 光纤单模连接器和模块状态 LED,例如 PRI、COM 和 OK,指示系统冗余和模块运行的健康状况。
Allen-Bradley 1756-RM 是一个 ControlLogix 冗余模块。该模块只能与 ControlLogix 平台一起使用以启用控制器冗余。它管理安装在具有相同组件和配置的相同机架中的两 (2) 个相同控制器的连接。它通过 PRI、COM 和 OK 等嵌入式 LED 显示器提供冗余系统监控以及模块健康状况。
1756-RM 已作为系列 A 和 B 发布。系列基本上是先前系列的增强,但是,具有不同系列的 1756-RM 可以在一个冗余配置中共存。强烈建议安装同一系列,以实现冗余设置的最大可操作性。与同系列的冗余模块一起使用时,速度可达100Mbps。
1756-RM 随附一 (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来配置该控制器以设置冗余,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 冗余模块在 1.2 伏直流时的电流消耗为 4 毫安,在 5.1 伏直流时为 1.2 安,在 24 伏直流时为 120 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,散热量为每小时 31 BTU。此 ControlLogix 带有开放式外壳,带有 T4 温度代码。就模块的物理特性而言,它的重量约为 0.29 千克或 0.64 磅,而且尺寸很小。1756-RM 模块的工作温度范围为 0 至 60 摄氏度(32 至 140 华氏度),可在 -40 至 85 摄氏度(-40 至 185 华氏度)的温度范围内存储。

【英文介绍】
The Allen-Bradley 1756-RM is a ControlLogix enhanced redundancy module. It is part of the Programmable Automation Controller (PAC) for controller redundancy. It comes with one (1) LC fiber optic single-mode connectors and module status leds, such as PRI, COM, and OK, indicating system redundancy and the health of module operation.
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 as well as module health through embedded LED displays such as PRI, COM and OK.
The 1756-RM has been released as series A and B. The series is basically an enhancement of the previous series, however, 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 redundant modules from the same series, speeds of up to 100Mbps can be achieved.
The 1756-RM comes 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. The controller can be configured using the Redundancy configuration tool to set the 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 redundancy module consumes 4 mA at 1.2 volts DC, 1.2 MA at 5.1 volts DC, and 120 mA at 24 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 heat dissipation of 31 BTU per hour. This ControlLogix comes with an open housing with a T4 temperature code. In terms of the physical characteristics of the module, it weighs about 0.29 kg or 0.64 pounds 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).
