Honeywell CC-PWRR01 – Redundant Power Supply Module for Series C / C300 I/O Powering

The Honeywell CC-PWRR01 is a redundant power supply module designed for Experion PKS Series C (C300) control cabinets. From my experience, it’s the go-to module when you need stable 24 VDC backplane power and want true 1+1 redundancy on critical I/O and controller racks. It slots directly into the Series C chassis and typically supports hot-swap replacement, so you can keep production running while maintaining the power system.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week for in-stock items; no more than one month at the latest
• Payment: 50% advance payment, full payment for delivery
• Express options: FedEx, UPS, DHL

Key Features

• Redundancy-ready design: Typically used in 1+1 pairs for uninterrupted backplane power; if one unit is removed or fails, the other keeps the chassis alive.
• Backplane-regulated output: Provides the regulated rails needed by Series C/C300 controllers and I/O modules; no extra DC/DC blocks in most cases.
• Status and health indication: Front-panel LEDs help technicians quickly verify power presence, module OK, and redundancy state.
• Hot-swap serviceability: You can replace a unit under load (in most cabinets), reducing planned downtime during maintenance.
• Protection built-in: Over-current and over-voltage protection mechanisms are typically included to safeguard the backplane and connected modules.
• Series C chassis fitment: Installs directly in the Series C/C300 power slot—no special brackets or wiring harnesses beyond standard cabinet power feeds.

Application Fields

Plants running Experion PKS with C300 controllers often standardize on CC-PWRR01 for redundant power in critical cabinets. You’ll see it in:

• Refining and petrochemical units where uninterrupted control is non-negotiable.
• Power generation (boiler and turbine controls) requiring quick swap during shifts.
• Pulp & paper and metals lines that need to avoid nuisance trips on long conveyors.
• Pharmaceutical process skids where validated uptime is a compliance requirement.
• Oil & gas upstream facilities, especially remote sites with UPS-backed 24 VDC.

A maintenance engineer told us they replaced one CC-PWRR01 during a refining unit turnaround while the partner unit kept the chassis powered—the cabinet never dropped, which saved them an extra half-day of startup checks.

Advantages & Value

• Reliability: Redundant architecture typically eliminates single-point power failures at the chassis level.
• Compatibility: Purpose-built for Series C/C300 racks, so the fit and backplane voltages are straightforward.
• Lower downtime risk: Hot-swapping and clear status LEDs make maintenance faster and safer.
• Lifecycle support: Honeywell’s mainstream ecosystem, with long-term parts availability in most regions.
• Cost control: Using standardized Series C spares simplifies inventory and reduces unique-stock carrying costs.

Installation & Maintenance

• Cabinet environment: Use a clean, ventilated enclosure; typical Series C cabinets are designed for 0–55°C and non-condensing humidity.
• Power feed: Supply from a stable 24 VDC source, ideally UPS-backed. Size wiring per local code and current draw of your full chassis.
• Grounding: Bond cabinet and backplane grounds properly; poor earthing often appears as intermittent module resets.
• Redundancy pairing: Install two CC-PWRR01 modules for 1+1. Verify load sharing and LED status after power-up.
• Hot-swap practice: When replacing a unit live, confirm the partner supply is healthy before you pull. ESD strap is recommended.
• Cleaning: Periodically remove dust with dry, oil-free air; keep ventilation paths clear to avoid thermal stress.
• Checks: Inspect terminal torque, LED indicators, and cabinet voltage annually or per site standards. No user-serviceable internals.

Quality & Certifications

• CE compliant
• UL/CSA recognized (typical for Series C modules)
• RoHS compliant
• Manufactured under ISO 9001 quality system
• Seller warranty: 365 days

Related & Supporting Components

To complete a cabinet build or plan spares, teams typically combine the CC-PWRR01 with:

• C300 controller assembly and Series C chassis/backplane
• Series C I/O modules such as CC-TAIX01 (AI), CC-TAOX01 (AO), CC-TDIL01 (DI), CC-TDOX01 (DO)
• 24 VDC UPS and cabinet power distribution hardware

You might notice that sites often carry two spare power supplies per system—one on the shelf and one in test cabinets—so swap-outs are always quick.
