Product Overview

The Honeywell TK-PPD011, part number 51309241-175, is a specialized Power Backup Extension Module designed for the Experion LS (Life Sciences) and Series 8 I/O architecture. Unlike standard consumer backup units, this industrial-grade module is engineered to provide supplementary power to C300 controllers and Series 8 I/O modules during primary supply fluctuations or total power failure. By extending the operational window of volatile memory (RAM), the TK-PPD011 ensures that critical process data, alarm configurations, and logic states are preserved until the system can be safely transitioned to a backup generator or brought to a controlled shutdown. This module is a vital component for maintaining data integrity in regulated industries where power interruptions could lead to significant batch loss or compliance discrepancies.

Industrial Resilience and Deployment Scenarios

This battery extension module is a prerequisite for facilities that operate under strict "zero-downtime" data requirements and high-availability safety protocols.

• Pharmaceutical Batch Protection Providing the necessary backup power to preserve recipe parameters and audit trail data in the event of a facility-wide power excursion.

• Controlled Lab Environments Ensuring that HVAC and environmental monitoring systems maintained by Experion LS remain synchronized and active during electrical maintenance.

• Critical Process Shutdowns Enabling C300 controllers to execute complex, multi-step safe-state sequences after the loss of primary power.

• Legacy System Modernization Upgrading the backup capacity of existing Series 8 control racks to meet updated corporate reliability and uptime benchmarks.

• Remote Terminal Unit (RTU) Support Bolstering the power stability of control nodes located in areas with unreliable grid infrastructure or high electrical noise.
