The Omron CPM2A-BAT01 is an original PLC memory backup battery designed for Omron CPM2A series programmable logic controllers and compatible Omron automation systems. This 3.6V lithium battery is used to preserve SRAM memory, PLC ladder programs, data registers, machine settings, and operational parameters during power interruptions or system shutdown.
The battery pack is commonly assembled using a high-reliability lithium thionyl chloride cell such as ER3V or ER17/33, providing stable voltage output, low self-discharge, and long service life for industrial standby applications. It includes a pre-installed connector cable for direct connection to compatible Omron PLC CPU units, ensuring quick and secure replacement without additional wiring.
The CPM2A-BAT01 is widely used in Omron CPM2A, CQM1H, CJ1G, and CJ1H PLC systems installed in industrial automation equipment, CNC machinery, packaging systems, conveyor systems, factory control panels, and process automation applications.
Designed for continuous industrial reliability, the battery maintains memory retention even when the PLC main power supply is disconnected. Its compact industrial battery pack design ensures dependable operation in harsh factory and automation environments.
