The Allen-Bradley 1756-M22 is a 750 KB non-volatile memory module designed specifically for use with ControlLogix 5555 controllers, compatible with models including 1756-L55 series variants. It is crucial to disconnect the battery from the controller prior to installation or replacement to avoid damage, and implement standard ESD precautions to ensure module integrity. Designed to withstand operating temperatures from 0 to 60 degrees Celsius and storage from -40 to 85 degrees, the module maintains stability across a 5 to 95% non-condensing humidity range, and meets T4 temperature code standards with shock ratings of 30 G operating and 50 G non-operating.
