TK-RPDXX1 Honeywell Experion PKS Redundant Power Supply Module

Honeywell TK-RPDXX1 Experion PKS Redundant Power Supply The Honeywell TK-RPDXX1, also cataloged as the TK-RPDXX1 Redundant DC Power Supply Module, operates as a dedicated hardware component for supplying regulated DC power to compatible control-system chassis and I/O hardware within Honeywell Experion PKS and Experion LS platforms. Hardware Specifications Parameter Specification Model TK-RPDXX1 Brand Honeywell Origin USA Weight 1.1 kg Dimensions 144 mm x 137 mm x 175 mm Operating Temp 0 to 60 deg C Power Consumption 110 W estimated input power (75 W max output at 60 deg C) Product Type Redundant DC Power Supply Module Product Family Experion PKS / Experion LS Input Voltage Range 16 to 32 VDC Maximum Backplane Output Current 1.5 A at 1.2 V; 4 A at 3.3 V; 13 A at 5.1 V; 2.8 A at 24 V Maximum Inrush Current 30 A at 19 to 32 VDC Power Configuration Redundant Coating Conformal-coated Channel-to-Channel Isolation & DCS Power Distribution To maintain stable process control across distributed control system architectures, the redundant power module delivers regulated DC rails while ensuring robust electrical isolation between input distribution lines and backplane circuitry. By incorporating internal filtering and overvoltage protection layers, the power supply shields sensitive processor cards and 4-20 mA HART loop protocol loops from common-mode electrical noise and high-frequency line transients originating in heavy industrial power feeds. Frequently Asked Questions Q: How does the redundant power configuration behave during a single module failure? A: In a properly configured dual-module setup, if one power supply fails, the remaining unit seamlessly continues supplying the required load provided total demand remains within capacity limits. Q: What does the "TK" prefix indicate regarding the physical construction of this hardware? A: The TK prefix designates a conformal-coated version engineered specifically to provide enhanced environmental protection against corrosive gases and high humidity in harsh industrial environments. Field Installation Guidelines Mount the power supply module securely in an upright orientation, positioned directly above or below the target control system chassis to maintain proper thermal convection. Ensure adequate physical clearance around the unit's cooling vents before terminating the 16 to 32 VDC input lines. Connect all equipment grounding wires firmly to the cabinet ground bus to mitigate electromagnetic interference and protect internal regulation circuits.
