1756-RMB 冗余模块 以启用控制器冗余
【产品详情】
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。它管理两(2)个相同控制器的连接，安装在具有相同组件和配置的相同机架中。它提供冗余系统监控以及模块健康通过嵌入式LED显示器，如PRI, COM和OK。
1756-RM已作为A系列和b系列发布。系列基本上是对前一个系列的增强，但是，具有不同系列的1756-RM可以在一个冗余配置中共存。强烈建议安装相同的系列，以实现冗余设置的最大可操作性。与同系列冗余模块配合使用时，速度可达100mbps。
1756-RM带有一个(1)单模LC光纤连接器。需要使用1756-RMCx冗余线缆同步冗余控制器对的操作。可以使用冗余配置工具来设置冗余，使用Studio 5000 Logix设计器来配置模块的总体参数来配置该控制器。
本模块兼容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。它是一个单槽模块，可以安装在机箱的任何可用槽位上。冗余对必须与伙伴机箱配置一致。
1756-RM的电流在1.2 vdc时为4 mA，在5.1VDC时为1.2 mA，在24VDC时为120 mA。
1756-RM冗余模块在1.2伏直流时的电流输出为4毫安，在5.1伏直流时为1.2安培，在24伏直流时为120毫安。该装置安装在一个底盘，它可以安装到任何插槽。1756-RM模块的功耗为9瓦，散热为31 BTU /小时。这个ControlLogix带有开放的外壳，它带有T4温度代码。就该模块的物理特性而言，它的重量约为0.29千克(0.64磅)，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)，可以在-40至85摄氏度(-40至185华氏度)的温度范围内存储。该装置是按照几个工业标准，它包括认证从CE, CSA, Ex, C-Tick，和c-UL-us标准。

【英文介绍】
The Allen-Bradley 1756-RM is a ControlLogix Redundancy module. This module may only be used with the ControlLogix platform to enable controller redundancy. It manages connectivity of Two (2) identical controllers, installed in an identical rack of the same components and configuration. It provides redundancy system monitoring as well as module health via the embedded LED display such as PRI, COM and OK.
The 1756-RM has been released as Series A and B. Series is basically an enhancement of the previous series however, a 1756-RM with different series can co-exist in one redundant configuration. It is highly recommended to have the same series installed to achieve maximum operability of the redundancy setup. When used with the same series of redundancy module, speed of 100 Mbps is achieved.
The 1756-RM comes with One (1) single mode LC fiber optic connector. It requires use of the 1756-RMCx redundancy cable to synchronize the operation of the redundant controller pair. This controller may be configured using the redundancy configuration tool for setting up the redundancy and Studio 5000 Logix designer for configuring 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 supply and 1756-PA75R, 1756-PB75R, 1756-PSCA2 redundant power supply. It is a single slot module and may be installed to any available slot in the chassis. The redundant pair must have the same configuration as to the partner chassis.
The 1756-RM has a Current draw of 4 mA at 1.2VDC, 1.2 mA at 5.1VDC and 120 mA at 24VDC operation.
The 1756-RM redundancy module has a current draw of 4 milliAmps at 1.2 Volts DC, 1.2 Amps at 5.1 Volts DC, and 120 milliAmps at 24 Volts DC. The unit mounts in a chassis and it can be fitted into any slot. The 1756-RM module has a power dissipation of 9 Watts along with thermal dissipation of 31 BTU per hour. This ControlLogix comes with open enclosure and it carries the T4 temperature code. In regard to physical characteristics of the module, it weighs around 0.29 kilograms or 0.64 pounds and it has small dimensions. The 1756-RM module has an operating temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and it can be stored within a temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The unit is made in accordance with several industrial standards and it includes certifications from the CE, CSA, Ex, C-Tick, and c-UL-us standards.
