OMRON documentation confirms CPM2A-BAT01 for CPM2A CPU memory backup. Other OMRON documentation also references this battery model for certain other equipment, so customers should verify the exact equipment model and required battery part number before ordering rather than relying on connector appearance alone.
Important Replacement Note
PLC backup batteries can protect important memory/data. Follow the equipment manufacturer’s replacement procedure carefully.
For example, OMRON documentation for applicable equipment can impose a limited replacement window after power is turned off to maintain memory backup. The correct procedure therefore depends on the controller being serviced.
If you’re unsure about compatibility, contact ArcEin with your PLC/controller model before ordering.
