Honeywell CC-PWRB01 Series C Power Supply Card

The Honeywell CC-PWRB01, also cataloged as the CC-PWRB01 Power Supply Card, operates as a dedicated hardware component for 24 VDC power generation and system bus distribution within Honeywell Experion PKS C300 platforms. It converts 120/240 VAC mains input into regulated direct current to energize controller processors, backplane buses, and associated I/O modules.

Hardware Specifications

Galvanic Isolation & Power Bus Conditioning

The Honeywell CC-PWRB01 incorporates internal transformer galvanic isolation barriers between the high-voltage AC utility input and the low-voltage 24 VDC output bus. The power architecture features integrated ripple filtering, over-voltage clamping, and over-current trip protection to prevent mains transients from propagating into sensitive controller logic. Designed for redundant operation, dual CC-PWRB01 units connect in a diode-ORed configuration to support seamless load sharing and power bus continuity without voltage drops or backplane disruption during a single AC feed loss.

Frequently Asked Questions

Q: Does the CC-PWRB01 power supply card support hot-swapping during system operation?

A: Yes, in a redundant dual power supply configuration, a faulty CC-PWRB01 card can be removed and replaced under live AC power without interrupting the 24 VDC power delivery to the C300 controller rack.

Q: How is the secondary power source maintained if primary 120/240 VAC mains power fails?

A: The system automatically transitions power draw to the attached 24 V backup battery assembly without switching latency, maintaining continuous operational voltage across the backplane bus.

Q: What mechanism prevents power supply thermal overload inside closed cabinets?

A: The module is engineered for passive heat dissipation up to 145 watts; thermal monitoring circuits flag fault diagnostics to the C300 system if internal component temperatures exceed safe operating thresholds.

Field Installation Guidelines

1. Verify that the incoming AC supply voltage matches the specified 120/240 VAC range before connecting power leads to the power distribution assembly.
2. Align the card edge and heavy-current connectors of the CC-PWRB01 with the designated power slot card guides in the C300 rack.
3. Slide the card firmly into place until the multi-pin backplane power connectors fully seat and the mechanical retention latches engage.
4. Ensure the 24 V backup battery assembly connections are correctly wired with solid polarity orientation at the terminal blocks.
5. Connect cabinet protective earth (PE) ground directly to the dedicated chassis grounding lug to ensure effective transient surge protection and noise immunity.
