1756-M14 扩展内存模块

1756-M14模块是由Allen-Bradley制造的易失性ControlLogix5555内存扩展模块。它属于a系列艾伦-布拉德利ControlLogix内存模块，它有3.5兆字节的容量。它是Allen-Bradley ControlLogix5555控制器的备件，支持冗余系统，可以与支持在同一模块上使用2个EEPROM单元的控制器的非易失性存储器一起使用。其简单的设计消除了安装模块时对特殊设备的需求，并且其插槽易于在控制器侧面获取。

1756-M14 ControlLogix5555内存扩展模块设计用于不会直接接触可能干扰其性能的腐蚀性材料的环境中。推荐使用温度范围为0 ~ 60摄氏度。不使用时，本模块应存放在-40至85摄氏度的温度范围内。安装、拆卸内存条前，请先切断所有电源，包括电池模块的电源，防止电弧损坏内存条。

The 1756-M14 module is a volatile ControlLogix5555 memory expansion module manufactured by Allen-Bradley. It belongs to the A-Series of Allen-Bradley ControlLogix memory modules and it has a 3.5-Megabyte capacity. It is a spare part for Allen-Bradley ControlLogix5555 controllers which support redundancy systems and which can be used alongside a nonvolatile memory for controllers that support the use of 2 EEPROM units on the same module. Its simple design removes the need for special equipment when installing the module and its slot is easily accessible on the side of the controller.

The 1756-M14 ControlLogix5555 memory expansion module is designed for use in environments where it would not have direct contact with corrosive material which could interfere with its performance. Its recommended operating temperature range is from 0 to 60 degrees Celsius. When it is not in use, this module should be stored within a temperature range of -40 to 85 degrees Celsius. To prevent electrical arcs that can potentially damage the 1756-M14 memory board, all power, including the battery module power must be disconnected before installing or removing the memory module.
