CC-PWRR20 Honeywell Experion PKS Series-C Power Supply Module

Configured for continuous regulated power distribution in Experion PKS Series-C architectures, the Honeywell CC-PWRR20 (CC-PWRR20 Power Supply Module) provides direct physical/electrical execution. It handles 24 VDC voltage output and 1:1 dual-module redundancy management across C300 controller and I/O sub-assemblies.

Hardware Specifications

Channel-to-Channel Isolation and Galvanic Power Decoupling

The Honeywell CC-PWRR20 delivers regulated 24 VDC output to backplane I/O sub-assemblies while maintaining isolation barriers between incoming universal AC mains and internal DCS logic buses. When driving field instrumentation loop supply channels operating on the 4-20 mA HART loop protocol, the module provides isolated power rail feeds that prevent common-mode line noise, voltage surges, and ground loops from propagating to C300 control processors. Built-in thermal protection and active load-sharing circuits manage energy distribution within redundant configurations.

Frequently Asked Questions

Q: How does the CC-PWRR20 execute failover during a power supply fault in a 1:1 redundant setup?

A: The onboard diode-ORing and sensing circuits monitor output status continuously. If one module experiences an AC line loss or internal fault, the paired secondary module immediately assumes full load execution without output voltage dips or backplane disruption.

Q: Is hot-swapping supported when replacing a degraded CC-PWRR20 module on an active Series-C rack?

A: Yes, the module features hot-swappable mechanical engagement pins that permit live replacement without de-energizing the cabinet bus or interrupting controller logic execution.

Field Installation Guidelines

1. Verify that the incoming supply voltage is within the specified 100-240 VAC range (50/60 Hz) before connecting input wiring to the terminal block.
2. Align the CC-PWRR20 module with the Series-C vertical rack slot or panel mounting rail and slide the unit inward until the backplane connectors latch completely.
3. Tighten the top and bottom mechanical mounting screws to establish continuous chassis frame grounding and secure the unit against operational vibration.
4. Route AC input power lines through dedicated raceways physically segregated from low-voltage 24 VDC output wires and 4-20 mA signal cables by at least 200 mm.
5. Connect cabinet protective earth (PE) ground to the designated ground stud on the mounting frame using a low-impedance conductor.
