【英文介绍】

The Allen-Bradley 1756-M22 module is a 750 KB non-volatile memory module for the Allen-Bradley ControlLogix 5555 controller. ControlLogix controllers compatible with the 1756-M22 module include 1756-L55, 1756-L55M12, 1756-L55M13, 1756-L55M14, 1756-L55M16, 1756-L55M22, 1756-L55M23, and 1756-L55M23 1756-L55M24 Controller. To prevent damage to the memory module, disconnect the battery from the controller before installing or replacing the memory module. Installing or replacing the 1756-M22 module on the ControlLogix 5555 controller requires the following four steps: Remove the controller side board, remove the existing memory board, install a new memory board, and replace the controller side board. Labels can be placed on the side of the controller to identify the type of memory board that is installed.

The 1756-M22 module is sensitive to ESD. To prevent module damage, take the following precautions: Touch grounding objects to release static electricity, wear a grounding wrist strap, avoid touching connectors or module components, use an ESD workstation, and store the module in an ESD container. The 1756-M22 module operates in a temperature range of 0 to 60 degrees Celsius. The module has a storage temperature range of -40 to 85 degrees Celsius. Relative humidity ranges from 5% to 95% (non-condensing). The module has a working and non-working impact rating of 30 G and 50 G respectively. The module housing opens to meet the T4 North American temperature specification and T4 IEC temperature specification.
