Description
Honeywell TC803B1004 Redundant Power Supply Module
Product Dimensions:
Honeywell offers highly reliable Redundant Power Supply Modules engineered for its flagship control systems, such as the Experion® PKS (Series C I/O) and the TDC 3000 system. The most prevalent modern variants belong to the Series C family, featuring models like the CC-PWRR01 or the 51306741-100 system power supplies.
Product Detailed Description
Honeywell Redundant Power Supply Modules operate in a active-sharing or hot-standby pair configurations within a dedicated power chassis. They are engineered to provide uninterrupted, highly regulated 24 V DC power to critical system components, including controllers (C300), I/O modules, and field devices.
If one power module fails or loses its upstream AC/DC source, the redundant module instantly assumes the full load without dropping system voltage, completely eliminating single points of failure in the system’s power infrastructure.
Typical Technical Parameters
Specifications below are typical for a standard Series C (e.g., CC-PWRR01) redundant power system.
| Parameter | Specification |
| Input Voltage Range | 100 to 240 V AC (Universal Input, 50/60 Hz) or 24 V DC (Model dependent) |
| Output Voltage | 24 V DC (Highly regulated) |
| Output Current Capacity | Typically 20 A per module (providing up to 40 A combined or 20 A redundant) |
| Efficiency | ge 88% at nominal load |
| Redundancy Type | 1+1 Diode-Ored, Active Current Sharing |
| Hold-up Time | ge 20 ms at full load (bridges short AC power interruptions) |
| Status Signaling | Dry contacts (Relay output) for “Power OK” and “Fault” status |
| Environmental Protection | Conformal coating options for G3 harsh environments |
Product Advantages
- True Hot-Swappable Design: A faulted power supply module can be extracted and replaced while the control system is live, without requiring any downtime or affecting process operations.
- Active Current Sharing: Both modules share the load equally during normal operation. This lowers the thermal stress on each individual module, significantly extending the overall lifespan of the hardware.
- Comprehensive Internal Diagnostics: Continuous monitoring of input voltage, output voltage, internal temperature, and fan status (if equipped), allowing early warning notifications on the SCADA/HMI.
- Superior Isolation: Protects sensitive controller backplanes from severe voltage spikes, surges, or ground faults originating from the main factory grid.
Important Considerations & Precautions
- Separate AC Feed Routing: To achieve true redundancy, the two power supply modules should be wired to independent AC sources (e.g., Grid A and UPS Grid B). Connecting both modules to the exact same upstream circuit breaker defeats the purpose of hardware redundancy.
- Ventilation and Clearances: Power modules generate localized heat. Ensure that cabinet cooling fans are operational and that the required clearances around the power chassis are maintained to prevent thermal shutdowns.
- Derating at High Temperatures: Review the manufacturer’s derating curves if operating the cabinet in environments exceeding 50°C, as maximum output current limits may decrease.
- Periodic Testing: Regularly check the status LEDs on the front of the modules and test the alarm contact circuits during planned maintenance turnarounds to ensure the failover mechanism remains completely functional.
Product Applications
Honeywell Redundant Power Supply Modules are mandatory in industries running continuous, safety-critical processes:
- Refineries & Petrochemical Plants: Powering Experion C300 controllers running critical distillation, cracking, and blending loops.
- Power Generation Facilities: Supplying continuous logic and instrumentation power for boiler control, turbine automation, and emergency trip networks.
- Offshore Oil & Gas Platforms: Used in remote, harsh marine environments where a power failure could jeopardize personnel safety and asset integrity.
- Pharmaceutical Manufacturing: Maintaining continuous batch process control where unexpected power loss can ruin high-value product batches and invalidate compliance data.
