Overview
The Allen-Bradley 1756-BATM is an external lithium battery module designed for ControlLogix controller platforms. It provides backup power to retain memory in the event of power loss and maintains memory retention during power loss, ensuring reliable storage of critical data and system states. This module is particularly useful in systems requiring battery replacement without removing the controller from service.
Key Features
- Supports Allen-Bradley 1756-BA2 lithium battery
- External battery holder mounts easily to DIN rail in control cabinet
- Contains a 3.6 VDC non-rechargeable lithium power source that delivers up to 20 mA
- Includes a replaceable battery cartridge (1756-BATA)
- Dimensions approx. 2.8 x 1.5 x 3.0 in (71 x 38 x 76 mm); weighs 0.35 lbs (0.16 kg)
- Operation shock rating of 30G when panel mounted and 15G on a DIN Rail
Technical Specifications
- Input rating of 15mA at 5.1V DC; output rating of 20mA at 3.6V DC with maximum battery discharge current of 20mA
- Operating temperature range 0°C to +60°C (32°F to 140°F)
- Relative humidity 5 to 95% non-condensing
- Includes 3.28-feet (1 meter) cable for connecting module to controller
- RoHS Compliant; 3 wire cable lead; 3 hole mount
- Internal battery typically lasts 3 to 5 years under normal environmental conditions; runtime during power loss generally allows at least 30 minutes to several hours of backup
Typical Applications
- Process control systems requiring volatile memory backup
- Manufacturing automation environments with extended downtime protection
- Safety-critical control systems requiring data retention during power loss
- Real-time clock preservation for sequence timing and scheduling
- Legacy ControlLogix retrofits and replacement module sourcing
