About 1775-ME8A

The Allen-Bradley 1775-ME8A PLC-3 Memory Module is a 32K words Static CMOS RAM module with Error Detection and Correction (EDC) capability, which is used for memory backup of the users’ program data.  This 32K word memory module is installed on the processor chassis slot of the 1775-A1 and –A2 chassis, and it draws 2.6 Amps of backplane current at +5 Volts DC and 0.15 Amps at 15 Volts DC. This memory has either lithium or nickel-cadmium battery backup, which provides extended and short power backup. Both lithium and cadmium batteries are field replaceable, but the lithium battery which provides power backup for up to 365 days is non-rechargeable, while the cadmium battery with 120 hours of short-term backup is automatically recharged when the memory module receives chassis power.

The 1775-ME8A monitors memory errors by automatically detecting and correcting any soft and hard single-bit errors in memory words, and it also monitors errors by carefully indexing accumulated error processes in the memory. The 1775-ME8A has 3 LED light indicators which provide status updates, and this LED indicator turns on when the module detects a memory error (steady red), corrects a memory error (steady yellow), and when the onboard battery can no longer provide backup (steady red). The 1775-ME8A is designed to operate between 0 and 60 degrees Celsius (32 and 140 degrees Fahrenheit) without damage to the backed up memories, and it is built for storage between 0 and 85 degrees Celsius (-40 and 185 degrees Fahrenheit).
