Honeywell TK-RPCXX1 Series C Redundant Power Carrier Module

Description

Providing regulated electrical distribution to Experion Series C chassis, the Honeywell TK-RPCXX1 serves as a reliable redundant power supply carrier within process automation environments. Engineered with a robust, conformal coated assembly, this module is specifically hardened against moisture, dust, and corrosive airborne contaminants typical of heavy industrial facilities. It accepts dual wide-range AC inputs to ensure continuous control system operation even in the event of a primary power feed failure.

Features

• Conformal Coated Circuitry: Designed for installation in harsh, Class G3 environments.
• Dual Redundant Power Architecture: Enhances system availability by facilitating hot-swappable secondary power supply configurations.
• Integrated Annunciation Relay: Built-in solid-state relay detects power failures and trips external diagnostic alarms.
• Wide AC Input Acceptance: Accommodates global voltage standards from 85 to 265 VAC without manual switching.

Applications

• Experion PKS Series C controller backplane power distribution.
• Petrochemical and oil refinery distributed control systems (DCS).
• Critical process industries requiring uninterruptible fieldbus and I/O power.

Empirical Engineering Insights

Alternative Models & Compatibility

The TK-RPCXX1 is the conformal-coated variant of the standard TC-RPCXX1 power carrier. In highly corrosive environments, the "TK" prefix series must be selected over the "TC" series to ensure long-term trace resilience against ambient hydrogen sulfide and chlorine. This carrier interfaces seamlessly with Honeywell Series C systems and connects via the TC-RPSC03 redundancy cable assembly.

Application Pitfalls & Engineering Notes

Maximum output power drops linearly above 60 degC ambient operating temperatures. Ensure that the module is mounted strictly in an upright orientation. Standard rack or panel configurations require at least 5 cm of clear space above and below the carrier chassis to allow natural thermal convection and avoid local hot spots inside the enclosure.

Commissioning & Wiring Tips

To minimize voltage sag and line-noise coupling, use exactly #14 AWG (1.4 mm) copper wire for the main AC feed. The integrated solid-state annunciation relay is highly sensitive to overcurrent; do not exceed the 100 mA load limit during commissioning tests, and always employ an external interposing relay if switching higher-current industrial indicator circuits.
