The Allen-Bradley 1772-ME16 RAM Module is a self-contained memory cartridge rated for 16K words of memory that is designed and manufactured by Allen-Bradley for use in second generation programmable logic controllers or PLC-2 controllers, specifically for the PLC-2, 2/30 models with chassis numbers 1772-LP3 and 1772-LP3D4. It has a pre-defined memory capacity of 16256 words. Like any random access memory module, the 1772-ME16 Module is the place where the data and information that the system needs to find quickly is stored. This electronic device has a maximum current rating of 1 Amp at 5 Volts DC and an approximate weight of 1.5 kilograms (3.31 pounds).

The Allen-Bradley 1772-ME16 RAM Module is made to be installed on a memory slot located at the right side for the PLC chassis and it is specifically keyed to enter only in that slot and in only one position. The design of the mounting slot and the memory module makes it impossible to connect them in the wrong location. The Allen-Bradley 1772-ME16 RAM Module is a volatile type of memory, meaning that it will lose all the information stored in it every time it gets disconnected from power. That is the reason why it needs to have a backup battery for keeping the data stored in case of long power disconnection. The first step for installing this RAM module is disconnecting the system power. The second step is to remove the front-right panel cover. The third step is to insert the RAM in the right-most plastic slot that can be found on the processor. The last step is to install the backup batteries as specified in the manufacturer’s manual.
