Configured for controller memory retention in ControlLogix systems, the Allen-Bradley 1756-BATM (1756-BATM Lithium Battery Assembly) provides direct electrical backup support for maintaining stored data during controller power interruption conditions.

Model Identification

The 1756-BATM is an externally mounted lithium battery assembly designed for Allen-Bradley ControlLogix controller systems. The assembly provides backup power support for memory retention functions and is installed with a horizontal mounting orientation.

Hardware Specifications

ControlLogix System Compatibility

The 1756-BATM is part of the ControlLogix hardware platform and functions as a dedicated battery assembly for controller memory backup applications. The component interfaces with the controller system through the specified battery connection arrangement rather than standard I/O communication channels.

ControlLogix hardware configuration requires correct battery installation and firmware-compatible controller operation. The battery assembly supports system data retention requirements during loss of external power.

Industrial Control Backup Characteristics

Allen-Bradley ControlLogix systems use structured hardware identification and firmware compatibility management for module operation. The 1756-BATM supports firmware flash compatibility checks through the controller platform, ensuring that installed hardware components match the configured ControlLogix architecture.

The battery assembly is not an I/O processing device and does not provide EtherNet/IP or ControlNet communication functions. Its electrical role is limited to backup energy supply for supported controller memory retention operations.
