>>>>>型號:1756-RM2 冗余增強型模塊 冗余光纖端口

【功能描述】

Allen-Bradley 1756-RM2是一個ControlLogix冗余模塊。它具有速度高達1000 Mbps的增強功能。當(dāng)與兩個機箱中的1756-L7x控制器配對時，它可以提供最佳的掃描性能。對于交叉負(fù)載，1756-RM2使用無單點故障的冗余光纖端口。在通道切換期間，處理機箱保持同步，而掃描時間可能會遇到大約10毫秒的延遲。它具有增強的安全功能，具有無干擾診斷功能。

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，熱耗散為21 BTU/小時。它可以安裝在ControlLogix機箱的任何插槽中。1756-RM2重0.64磅。它有一個開放的外殼。對于通信，它支持多達7個增強型控制網(wǎng)絡(luò)和以太網(wǎng)/IP通信模塊。對于布線，1756-RM2支持1756-RMC1、1756-RMC3和1756-RMC10電纜，長度分別為1米、3米和10米。

【英文介紹】

Allen-Bradley 1756-RM2 is a ControlLogix redundant module. It has enhanced features with 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 optic 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 has enhanced security features with 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. 1756-RM2 weighs 0.64 LBS. It has an open shell. For communication, it supports up to 7 enhanced control networks and Ethernet /IP communication modules. For cabling, the 1756-RM2 supports 1756-RMC1, 1756-RMC3, and 1756-RMC10 cables in lengths of 1, 3, and 10 meters, respectively.
