Honeywell TK-RPDXX1 Redundant DC Power Supply
The TK-RPDXX1 is a 24 VDC redundant power supply designed for Honeywell Experion LS and Series A control-system chassis. Operating from a nominal 24 VDC input range (16 to 32 VDC), it delivers regulated multi-rail DC power directly to the system backplane to support continuous controller and I/O module operation. The TK designation identifies the conformally coated version, providing enhanced environmental protection for sensitive internal electronics.
Backplane Power Distribution & Redundancy
Engineered for dual-supply redundant power architectures, two TK-RPDXX1 units operate in parallel so that a single power supply failure will not interrupt chassis operations. The module delivers up to 75 W total output power at 60 deg C across multiple backplane voltage rails: 1.5 A at 1.2 VDC, 4 A at 3.3 VDC, 13 A at 5.1 VDC, and 2.8 A at 24 VDC.
Monitoring & Integration Features
The unit includes a solid-state relay annunciation output rated up to 120 VAC/VDC at 100 mA maximum for real-time power supply status signaling and fault alarm routing. Designed for upright mounting in proximity to the target chassis, input power connects via 14 AWG wire terminals. The power supply integrates with the system using related hardware accessories including the TC-PRSC04 power cable and TC-RPSCA2 chassis adapter.

Frequently Asked Questions
Q: How does the TK-RPDXX1 maintain power continuity during a power supply fault? A: In a dual-supply redundant configuration, two TK-RPDXX1 units share the load; if one module fails, the remaining unit seamlessly assumes the full power load without interrupting chassis operations.
Q: What is the significance of the TK prefix in the model number? A: The TK prefix indicates that the circuit board assembly features conformal coating for superior protection against humidity and airborne contaminants compared to the standard TC-series version.
Q: What power accessories are associated with this power supply? A: The module is designed to connect using the TC-PRSC04 power cable and interfaces with the chassis using the TC-RPSCA2 chassis adapter.
