Industry Applications
Manufacturing Line Backup
In automated production lines, the 1756-BATM provides essential backup power for ControlLogix processors. If a power dip occurs, the battery maintains volatile memory, preventing loss of production recipes or machine states. Its 1.7Ah capacity ensures extended hold-up time during brief outages.
Process Control Memory Retention
For continuous process industries like chemical or food processing, losing controller memory can cause costly downtime. This lithium cell offers a lower self-discharge rate than Ni-Cad or NiMH batteries, meaning longer intervals between replacements. The 10-year shelf life reduces inventory management burden.
Remote Monitoring Stations
In remote or harsh environments, the wide operating temperature range of -60 to +85 degrees Celsius (ambient) makes the 1756-BATM suitable for unheated enclosures. The 30G shock rating when panel mounted ensures reliability in high-vibration settings like pump stations or compressor skids.
Installation & Setup Guidance
Mount the 1756-BATM either directly to the panel or on a DIN rail using the required DIN rail lock. Use the included 3.28-feet cable to connect the battery assembly to the controller. For external mounting, an adapter cable is needed. Ensure wiring uses 1-meter Category 3 cables for proper signal integrity. The module has no particular enclosure type rating, so any enclosure can be used as long as it meets environmental requirements.
Maintenance & Reliability
Inspect the battery periodically for physical damage or corrosion at the connector. Keep the storage temperature at or below 30°C (86°F) to maximize shelf life. Replace the battery every 10 years or when the controller indicates low battery voltage. The lithium chemistry provides stable voltage output until near depletion.
Compatibility & Integration
The 1756-BATM is compatible with Allen-Bradley ControlLogix processors including the 1756-L55M14, 1756-L55M16, 1756-L6x series, and the 1756-L61, 1756-L62, and 1756-L63 controllers. It works with the 1756-BATA single-cell lithium battery arrangement. The module draws a maximum of 4.5 Watts from the backplane.
Selection Guide & Purchasing Advice
When selecting a replacement battery for your ControlLogix system, verify the processor model and mounting requirements.
