Honeywell Experion DCS TC-PPD011 Power Support Extension Card

Product Overview

The Honeywell TC-PPD011 (51309241-125) functions as a dedicated hardware battery extension module within the Experion LS control system family. This expansion hardware directly secures system data integrity by maintaining auxiliary power to critical processor components.

Continuous processing facilities depend on this module to safeguard their system configuration profiles. Consequently, the device prevents catastrophic system downtime and data corruption during unexpected facility blackout events.

Technical Architecture and Power Allocation

This module incorporates a high energy density lithium-ion storage cells engineered for extended standby lifecycles. The internal charging circuitry draws power directly from the system backplane to maintain the battery at an optimal readiness state.

During active operation, the module exhibits highly efficient power consumption profiles across separate voltage rails. Specifically, the card draws 0.036 Amps on the 24 VDC rail and 0.112 Amps on the 5 VDC rail.
