>>>>>型号:1756-RM2 冗余模块 具有增强功能
【功能描述】
Allen-Bradley 1756-RM2是一款ControlLogix冗余模块。它具有增强功能，速度高达1000 Mbps。当与两个机箱中的1756-L7x控制器配对时，它可提供最佳的扫描性能。对于交叉负载，1756-RM2使用冗余光纤端口，没有单点故障。在通道切换期间，处理机箱保持同步，而扫描时间可能会遇到大约10毫秒的延迟。它具有增强的安全功能和无干扰诊断功能。
1756-RM2冗余模块在5.1V DC时消耗1.16 A电流，在24V DC时消耗3.4 mA电流。它的最大功耗为6W，散热为21 BTU/小时。它可以安装在ControlLogix机箱的任何插槽中。1756-RM2重0.64磅，有一个开放式外壳。在通信方面，它支持多达7个增强型ControlNet和EtherNet/IP通信模块。在接线方面，1756-RM2支持1756-RMC1、1756-RMC3和1756-RMC10电缆，长度分别为1m、3m和10m。
ControlLogix 5560和ControlLogix 5570系列控制器支持1756-RM2模块。冗余模块配置工具，RSLinx 2.59。
根据所使用的冗余模块的组合，可以启用各种同步速度。特别是，如果与相同的1756-RM2模块一起使用，速度可能高达1000 Mbps。如果同时使用A系列或B系列1756-RM2，速度可能高达100 Mbps。使用1756-RM2冗余模块可实现长达20 ms的控制器切换。

【英文介绍】
The Allen-Bradley 1756-RM2 is a ControlLogix redundant module. It has enhanced features and speeds up to 1000 Mbps. When paired with the 1756-L7x controller in both cases, it provides the best scanning performance. For cross loads, the 1756-RM2 uses redundant fiber ports with no single point of failure. During channel switching, the processing chassis stays synchronized, while scan times can experience a delay of about 10 milliseconds. It features enhanced security features and interference-free diagnostics.
The 1756-RM2 redundant module consumes 1.16A current at 5.1V DC and 3.4 mA current at 24V DC. It has a maximum power consumption of 6W and a heat dissipation of 21 BTU/ hour. It can be installed in any slot in the ControlLogix chassis. The 1756-RM2 weighs 0.64 LBS and has an open housing. In terms of communication, it supports up to seven enhanced ControlNet and EtherNet/IP communication modules. In terms of wiring, the 1756-RM2 supports 1756-RMC1, 1756-RMC3 and 1756-RMC10 cables with lengths of 1m, 3m and 10m respectively.
The ControlLogix 5560 and ControlLogix 5570 series controllers support 1756-RM2 modules. Redundant module configuration tool, RSLinx 2.59.
Depending on the combination of redundant modules used, various synchronization speeds can be enabled. In particular, if used with the same 1756-RM2 module, speeds can be as high as 1000 Mbps. If you use A series or B Series 1756-RM2 at the same time, the speed can be as high as 100 Mbps. The 1756-RM2 redundant module enables controller switching of up to 20 ms.
