Product Details
Configured for high-availability regulated 24 VDC power distribution in Honeywell Experion PKS and TDC 3000 DCS platforms, the Honeywell PN-45346 (TC-RPCXX01 Redundant Power Supply Module) provides direct physical/electrical execution. It integrates dual-input circuitry accepting independent AC power feeds to execute automatic load switching without output interruption. The assembly maintains direct rail interface connections to ensure continuous operational power across system controllers and downstream I/O racks.

Process Control & DCS Diagnostics
The module provides full channel-to-channel isolation across internal regulation circuits, preventing fault propagation between AC input lines and DC output rails. Designed to operate within 4-20 mA HART loop protocol environments and high-density fieldbus networks, the internal transformer secondary stages minimize common-mode noise and ripple voltages. This isolation profile maintains steady instrumentation reference levels and protects sensitive digital and analog process I/O channels from upstream AC line transients.
Frequently Asked Questions
Q: What is the behavior of the output rail during an AC input supply failure?
A: The switchover circuitry transfers execution to the active secondary AC source within milliseconds. The regulated 24 VDC output remains strictly within standard voltage tolerances without voltage drops that could cause system controller resets.
Q: Can the TC-RPCXX01 module be removed under power during live system operation?
A: Hot-swap capability depends on the backplane slot architecture of the host power chassis. In active dual-redundant power configurations where the parallel module carries the full load, online removal and insertion are supported provided the chassis backplane supports online servicing.
Field Installation Guidelines
- Chassis Alignment: Align the module guide rails with the designated slots in the power chassis. Firmly press the module until the backplane edge connectors fully seat to establish high-current DC rail contacts.
- Feed Isolation: Wire the primary and secondary AC inputs to independent branch circuits (such as utility grid power and an uninterruptible power supply feed) to ensure true hardware fault redundancy.
- Cabinet Ventilation: Maintain a minimum vertical clearance above and below the module chassis to facilitate natural convection cooling, avoiding heat accumulation near the +70 deg C operating limit.
- Grounding & Shielding: Secure the chassis grounding lug directly to the cabinet ground bus bar with low-impedance copper conductors to ensure proper surge protection and noise suppression.
