The TK-PPD011 (51309241-175) is a battery extension module designed for the Honeywell Experion PKS Series C and C300 controller infrastructure. It provides backup power for volatile memory (RAM) in controllers, ensuring that system configurations, runtime data, and event logs are preserved during unexpected power interruptions.
This module is engineered for seamless integration within Series C cabinets, extending the memory-hold time of standard controller batteries. Its compact design allows controllers to perform orderly transitions to backup states without data loss or corruption, making it essential for plants with unstable power grids or systems where recovery time is critical.
