About 1775-MR8

The 1775-MR8 is a CMOS RAM memory unit that is manufactured by Allen-Bradley. This memory module is suitable for all PLC-2 programmable controllers. As a Complementary Metal Oxide Semiconductor RAM memory unit, the 1775-MR8 module is powered by a lithium battery. CMOS RAMs such as the 1775-MR8 run on about a millionth of an Amp of current. This makes it efficient for the memory module to store data electronically for a very long time with low power consumption.

The 1775-MR8 unit is a 32K RAM memory module. It provides storage for all user programs, message areas, I/O image tables, and data tables. The 1775-MR8 stores data in voltage level forms. These voltage levels are put in storage as binary digits of 1 or 0, which represent the smallest areas of a memory unit. The Allen-Bradley 1775-MR8’s dimensions are as follows: a diameter of 1.33 inches and a length of 2.40 inches. On the other hand, the nominal voltage of the 1775-MR8 is 3.6 Volts.

For users to prolong the performance and life of this memory module, it is recommended that they store the 1775-MR8 unit within a temperature range of  -55 degrees Celsius to 85 degrees Celsius. At 60 degrees Celsius, users will get about 24 months of backup battery life. While installing the 1775-MR8, make sure to disconnect the power line and wait for about 60 seconds before removing or installing the CMOS RAM memory. If the users fail to do so, they run the risk of getting injured. Like all CMOS memory modules, the 1775-MR8 requires a single slot in the processor chassis of the drive that is connected to.
