Honeywell CC-PWRR01 C300 Redundant Power Supply Module

Description

Delivering regulated, highly reliable power distribution within the Experion C300 controller subsystem, the Honeywell CC-PWRR01 functions as a dual-channel redundant power source designed to protect critical process control loops from input line failures. This module integrates directly into the Series C power carrier assemblies, allowing for seamless load-sharing, active diode auctioning, and uninterrupted power handovers. Engineered specifically to meet the high-availability demands of modern continuous process environments, the Honeywell CC-PWRR01 stabilizes system voltages, filters electromagnetic interference, and provides real-time diagnostic status feedback directly to the controller architecture.

Features

• Active Redundant Load-Sharing: Seamlessly balances the current demand between paired power modules to extend component lifecycle and ensure zero-millisecond failover.
• Hot-Swappable Architecture: Permits safe removal and replacement of a faulted power supply module while the process system remains fully energized.
• Diagnostic Status Indication: Front-panel LEDs provide immediate, clear visual states of input power viability, output regulation, and over-temperature faults.
• Integrated Diode Auctioning: Eliminates the risk of back-feeding or circuit disruption in the event of an internal component short-circuit.
• Heavy-Duty Industrial Filtering: Built-in transient voltage surge suppression (TVSS) shields downstream C300 controllers and Series C I/O modules from grid irregularities.

Applications

• Petrochemical refining and high-availability chemical synthesis plants.
• Base-load and peak-generation thermal and combined-cycle power facilities.
• Continuous process pulp, paper, and metallurgy control networks.
• Offshore oil platform Emergency Shutdown (ESD) and Fire & Gas (F&G) systems.

Alternative Models & Compatibility

The CC-PWRR01 is designed specifically for insertion into the CC-PWRB01 (or equivalent) redundant power carrier. When performing system upgrades or migrations from legacy Experion platforms, verify that your existing carrier backplane is rated to accept Series C Form-Factor modules, as keying pins prevent physical mismating with non-compatible I/O racks.

Application Pitfalls & Engineering Notes

To guarantee optimal MTBF, maintain at least 50mm of clear space above and below the power carrier assembly to allow unobstructed convective airflow. In highly enclosed or non-ventilated field cabinets, thermal concentration can cause premature aging of the internal electrolytic capacitors. Always implement external ambient monitoring within the cabinet to ensure temperatures do not exceed the 60 degC threshold.

Commissioning & Wiring Tips

When bringing a redundant pair online, energize the primary and secondary power sources from isolated feed breakers. This layout ensures that an upstream breaker trip on Feed A does not compromise Feed B. Utilize the dry-contact alarm terminal block on the redundant carrier to route power fail status signals back to your diagnostic alarm logs in Experion PKS.
