IC200ACC414 | GE Fanuc | Backup Battery

Description

The GE Fanuc IC200ACC414, also cataloged as the IC200ACC414 Backup Battery, operates as a dedicated hardware component for RAM and real-time clock retention within VersaMax Micro PLC networks. This cylindrical lithium unit supplies continuous DC voltage directly to the internal volatile memory registry and scheduling circuits during loss of primary backplane power, eliminating data corruption across compatible 20, 23, 28, 40, and 64-point systems.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Flash Compatibility

The installation of the IC200ACC414 backup battery operates independently of the backplane bus communication velocity, ensuring that zero bus latency or transmission bottlenecks are introduced into the PLC platform. During firmware flash execution or active controller runtime, the battery circuit isolates its electrical charge from the logic processing units to prevent cross-talk or voltage ripples. Upon localized power loss or planned shutdown events, the hardware automatically switches to the battery loop, maintaining memory registry arrays and real-time clock variables without dropping bits or corrupting volatile data blocks.

Frequently Asked Questions

Q: Does replacing the IC200ACC414 battery during a power-off state cause data loss?

A: Yes. If primary backplane power is disconnected and the battery is removed, the volatile RAM contents and real-time clock settings will be cleared. Always replace the battery while the PLC remains energized by the main power supply to ensure continuous register retention.

Q: Can this battery pack be charged via the internal PLC power bus?

A: No. The IC200ACC414 is a primary, non-rechargeable lithium battery. Attempting to charge this cell via the internal PLC bus or an external power supply can lead to thermal runaway, cell rupture, or permanent destruction of the host PLC battery compartment.

Field Installation Guidelines

• Electrostatic Discharge (ESD) Mitigation: Ground all field personnel using appropriate ESD wrist straps connected to a verified earth ground point prior to opening the internal PLC battery compartment.
• Polarity Verification: Ensure correct axial alignment when inserting the battery into the internal socket. Reversing the positive (+) and negative (-) terminals will prevent operation and may degrade the contact infrastructure.
• Housing Seal Check: Ensure the compartment door or structural latch mechanism clicks into a locked position to maintain mechanical vibration resistance during active machine cycles.
• Disposal Controls: Follow standard industrial protocols for lithium cell processing. Do not crush, puncture, or incinerate the removed battery component.
