Siemens SIMATIC S7-200 SMART SB BA01 - 6ES7288-5BA01-0AA0 | Battery Signal Board

FAQ Section 

Q: Does it come with a battery pre-installed?

• • A: Usually, the board is sold as the carrier, and a standard CR2032 battery is used. Check the packaging for the cell.

• Q: Can I use an Analog Signal Board and a Battery Board at the same time?

  • A: No, most S7-200 SMART CPUs have only one Signal Board slot. You must choose between I/O expansion (like SB AE01) or the Battery Board.

• Q: How do I know when to change the battery?

  • A: The "STOP" or "ERROR" LED on the CPU will often blink, or you can check the System Bits (SM bits) in the software to monitor battery status.
