>>>>>型號:1756-RM2 冗余模塊 具有增強(qiáng)功能
【功能描述】
Allen-Bradley 1756-RM2是一款ControlLogix冗余模塊。它具有增強(qiáng)功能，速度高達(dá)1000 Mbps。當(dāng)與兩個機(jī)箱中的1756-L7x控制器配對時，它可提供最佳的掃描性能。對于交叉負(fù)載，1756-RM2使用冗余光纖端口，沒有單點(diǎn)故障。在通道切換期間，處理機(jī)箱保持同步，而掃描時間可能會遇到大約10毫秒的延遲。它具有增強(qiáng)的安全功能和無干擾診斷功能。
1756-RM2冗余模塊在5.1V DC時消耗1.16 A電流，在24V DC時消耗3.4 mA電流。它的最大功耗為6W，散熱為21 BTU/小時。它可以安裝在ControlLogix機(jī)箱的任何插槽中。1756-RM2重0.64磅，有一個開放式外殼。在通信方面，它支持多達(dá)7個增強(qiáng)型ControlNet和EtherNet/IP通信模塊。在接線方面，1756-RM2支持1756-RMC1、1756-RMC3和1756-RMC10電纜，長度分別為1m、3m和10m。
ControlLogix 5560和ControlLogix 5570系列控制器支持1756-RM2模塊。冗余模塊配置工具，RSLinx 2.59。
根據(jù)所使用的冗余模塊的組合，可以啟用各種同步速度。特別是，如果與相同的1756-RM2模塊一起使用，速度可能高達(dá)1000 Mbps。如果同時使用A系列或B系列1756-RM2，速度可能高達(dá)100 Mbps。使用1756-RM2冗余模塊可實現(xiàn)長達(dá)20 ms的控制器切換。

【英文介紹】
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.
