Allen Bradley 1756-BA1 ControlLogix FlexLogix Battery

 

Description

The 1756-BA1 ControlLogix/FlexLogix Battery Assembly by Allen-Bradley is a lithium battery assembly for the Allen-Bradley 756-L55, 1756-L61, 1756-L62, 1756-L63, and 1794-L33 controllers. Specifically, the 1756-BA1 is a Sanyo Lithium Cylindrical SE Type Cell Battery with the following battery ratings: 3V DC terminal voltage, and 1800mA of nominal battery capacity. The battery has lithium contents and uses a lead wire connector terminal. It fits into an open-style enclosure.

The 1756-BA1 is a lithium battery by Allen-Bradley used for the Series A 1756 –L6 controllers. These include the 1756-L55, 1756-L61, 1756-L62, 1756-L63, and also the 1794-L33 controllers. The 1756-BA1 contains manganese dioxide at a concentration range of between 30 and 40%. The 4 lithium metal concentration percentage on the 1756-BA1 is 2.9% while the mixture of solvent of carbonate and ether is 12 to 18%. Basically, the 1756-BA1 is a Sanyo lithium cylindrical SE type of cell battery. The ratings for the 1756-BA1 are 3 Volts DC terminal voltage and 1800 mA on the nominal battery capacity. As indicated above, the 1756-BA1 comes with lithium contents and it uses a lead wire connector terminal. The 1756-BA1 is designed to fit into an open style enclosure. The backplane current is 10 Amps for 5 Volts DC while for the 24 Volts DC the backplane current should be 2.8 Amps.

The operational temperature ranges between -40 and 60 degrees Celsius. The ambient storage temperature is 30 degrees Celsius. Under circumstances where the temperature of a machine operating beneath the 1756-BA1 is 1 degree Celsius above 30 degrees Celsius, consider changing the 1756-BA1 battery within 3 years. Ideally, the higher the surrounding temperature, the sooner the battery should be replaced. The 1756-BA1 weighs 17 grams while the dimensions are 20 × 24 × 8 inches. The 1756-BA1 should be handled with care. When handling the 1756-BA1, avoid crushing it and do not expose the 1756-BA1 to excessive physical shock. The 1756-BA1 positive and negative terminals should not be short-circuited with any conductive metals. A damaged 1756-BA1 should be placed into a suitable container or a sealed plastic bag after cooling. Note that in case of accidental short-circuiting, even for a few seconds, this reduces the 1756-BA1 battery life.

Q1: How often should I replace the 1756-BA1 battery?

A: The battery typically lasts 2 to 5 years, but it is recommended to replace it when the low battery warning appears on the PLC system.

Q2: How do I know when the battery needs replacement?

A: The ControlLogix PLC system provides a battery status indicator that alerts users when the battery is running low.

Q3: Can I replace the battery while the system is running?

A: Yes, the 1756-BA1 battery is designed for hot-swapping, allowing safe replacement without shutting down the controller.
