Description

Product Overview

The IC200ACC403 is a lithium-based backup battery assembly designed for the GE Fanuc Emerson VersaMax Micro PLC platform. It provides essential power retention for volatile memory, ensuring that system configuration, process data, and diagnostic information are preserved during power loss conditions.

This coil-cell battery unit is engineered for direct integration into VersaMax Micro controllers and is monitored by the PLC system for battery health and fault indication.

Functional Role

The IC200ACC403 is critical for maintaining non-volatile operation continuity in VersaMax Micro PLC systems. It ensures that program logic retention, configuration parameters, and runtime data remain intact when primary power is unavailable.

Battery condition is continuously supervised by the controller, allowing predictive maintenance before failure occurs.

Application Areas

• VersaMax Micro PLC memory retention systems

• Industrial controller backup power support

• Control system configuration preservation

• Field-installed PLC maintenance replacement kits

• Automation systems requiring non-volatile data integrity

Engineering Notes

This battery assembly should be replaced according to manufacturer lifecycle recommendations or when diagnostic indicators report low voltage conditions. Proper handling is required due to lithium chemistry; replacement should be performed with system power isolation where applicable.

FAQ

Q1: What happens when the battery is depleted?
The PLC may lose stored data, including configuration and runtime memory, upon power loss.

Q2: Is the battery monitored by the PLC system?
Yes, battery health is tracked through built-in diagnostic status bits and fault reporting.

Q3: Can this battery be replaced while the system is running?
Replacement procedures depend on system configuration; in most cases, controlled shutdown is recommended.
