Industrial Power Redundancy Solution – Honeywell TC-RPSCA2 | C300 Series
The Honeywell TC-RPSCA2 is a dedicated redundant power supply module engineered for mission-critical distributed control systems. Designed for the Honeywell C300 Controller platform within the Experion PKS architecture, this module eliminates single points of failure in plant power distribution — keeping your process running even when one supply fails.
Where This Product Is Used
The TC-RPSCA2 is specified by control engineers and system integrators across industries where unplanned downtime carries significant safety or financial risk:
- Oil & Gas Refineries — Continuous power to C300 controllers managing distillation columns, compressor trains, and safety instrumented systems (SIS).
- Chemical & Petrochemical Plants — Redundant power for reactor control loops and batch process automation where power interruption triggers costly shutdowns.
- Power Generation (Thermal & Nuclear) — Sustaining DCS controller availability in turbine control and boiler management systems.
- Pulp & Paper Mills — Reliable power backbone for multi-loop process control in continuous production environments.
- Pharmaceutical Manufacturing — Supporting validated control systems under FDA 21 CFR Part 11 environments requiring high availability.
- Water & Wastewater Treatment — Ensuring uninterrupted SCADA/DCS operation for pumping stations and treatment process control.

Application-Specific FAQ
Q: Is the TC-RPSCA2 compatible with all Experion PKS revisions?
A: The TC-RPSCA2 is designed for the C300 platform within Experion PKS R400 and later. For earlier revisions (R300 and below), please confirm compatibility with your system’s hardware revision guide or contact our technical team.
Q: Can I install the TC-RPSCA2 while the C300 controller is online?
A: Yes. The hot-swap design allows installation and replacement without powering down the controller chassis, provided the redundant supply is already active.
Q: What happens if both power supplies fail simultaneously?
A: In a dual-failure scenario, the C300 controller will perform a controlled shutdown. The TC-RPSCA2 is designed to prevent this by providing independent supply paths with individual fault alarms.
Q: Do you supply the TC-RPSCA2 with a certificate of conformance?
A: Yes. A certificate of conformance (CoC) is available upon request for all new and new-surplus units.
Q: What is the difference between TC-RPSCA2 and TC-RPSCA1?
A: The TC-RPSCA2 is the second-generation redundant power module with enhanced diagnostics and improved thermal management. Please verify your chassis compatibility before ordering.
