Honeywell TK-PPD011 51309241-175 51204142-100 C200 Battery Extension Module

Product Overview
The TK-PPD011 (Part Numbers: 51309241-175 / 51204142-100) is a dedicated Battery Extension Module (BEM) for the Honeywell Experion PKS C200 controller system. It provides an auxiliary power source for the C200 processor, ensuring that critical system data—including control programs, runtime configurations, and volatile memory—is preserved during a main power interruption.

By extending backup duration, the TK-PPD011 can provide up to 12 hours of memory retention depending on system load. It installs directly within the Series-A chassis and features advanced internal circuitry to monitor battery health and charge status, reporting real-time diagnostics to the supervisory control system.

Technical Specifications

Application Scenarios

• Preserving control logic and setpoints during facility-wide power outages

• Extending data retention for remote control nodes in petrochemical and utility sectors

• Ensuring safe shutdown sequences in fault-tolerant systems

Frequently Asked Questions (FAQ)

Q: Is the TK-PPD011 a pressure sensor?
A: No. Despite some misclassifications, the TK-PPD011 is strictly a Battery Extension Module for backup power and data preservation, not a pressure sensor.

Q: How does the module report its status?
A: It integrates with Honeywell C200 diagnostics, enabling operators to monitor battery health, charge level, and module status via the Experion PKS HMI.
