Honeywell FC-IOCHAS-0002R Replacement for Experion PKS C300

Product Overview

Honeywell FC-IOCHAS-0002R Replacement for Experion PKS C300: Seamless Migration & Smooth Transition

Upgrading or replacing a legacy distributed control system is one of the most operationally sensitive tasks in industrial automation. The Honeywell FC-IOCHAS-0002R I/O Chassis Power Supply Module is a critical component within the Experion PKS C300 Series architecture, providing regulated DC power to the C300 I/O chassis and all field I/O modules mounted within it. When this module reaches end-of-life, becomes obsolete, or fails unexpectedly, the entire I/O subsystem it supports is at risk of unplanned downtime.

At TOPNLMS, we specialize in sourcing, testing, and supplying hard-to-find and discontinued Honeywell Experion PKS components. Our stock of FC-IOCHAS-0002R units is pre-tested, fully inspected, and ready for immediate dispatch — minimizing your plant’s exposure to extended outages.

Seamless Upgrade Solutions

A successful migration from a failed or obsolete I/O chassis power supply rarely involves a single component. In practice, field engineers replacing an FC-IOCHAS-0002R in a live Experion PKS C300 environment will typically audit the surrounding subsystem at the same time. The C300 controller module itself — often the HC-CCPF01 or HC-CCPF01R — should be inspected for firmware currency and communication health over the plant’s Fault Tolerant Ethernet (FTE) network before the chassis power supply is swapped.

Within the same I/O chassis, Series C300 analog input modules such as the FC-AI01 and digital output modules like the FC-DO01 share the regulated 24 VDC bus supplied by the FC-IOCHAS-0002R. If the power supply has been running in a degraded state, these I/O modules should be checked for latent faults before returning the chassis to service. Similarly, the FC-IOCHAS-0004 expanded chassis — used in larger I/O node configurations — relies on the same power supply form factor, making this an ideal time to standardize spare inventory across both chassis types.

For sites running redundant power configurations, the companion FC-IOCHAS-0002R redundant power supply module should be verified simultaneously. Redundant PSU pairs in Experion PKS are designed for bumpless switchover, but only when both units are within specification. Engineers should also confirm that the FC-IOCHAS-0002 chassis backplane is free of corrosion or connector damage before inserting the replacement module.

Communication continuity is maintained through the C300 controller’s FTE ports, which connect to the plant’s Cisco IE series industrial Ethernet switches or equivalent managed switches. No IP reconfiguration or Experion Station software changes are required when replacing the chassis power supply — the C300 controller and its associated IOLINK connections remain fully operational during a hot-swap on a redundant-PSU chassis.

For sites that are simultaneously upgrading from older TDC 3000 or PlantScape legacy systems to Experion PKS, the FC-IOCHAS-0002R is a standard component in the new I/O infrastructure. In these broader migration projects, complementary components such as the MC-TAIH02 analog input terminal assembly, MC-TDID12 digital I/O terminal board, and CC-TAIX01 thermocouple input terminal assembly are commonly ordered alongside chassis power supplies to complete the I/O node build-out.

If your retrofit project also involves upgrading the operator interface layer, Honeywell’s Experion Station HMI software and associated FTE network infrastructure components should be scoped in parallel. TOPNLMS can assist in identifying and sourcing the full bill of materials for your C300 I/O node expansion or replacement project.

Retrofit Guidance FAQ

Q: Do I need to modify any field wiring when replacing the FC-IOCHAS-0002R?
No. The FC-IOCHAS-0002R is a direct drop-in replacement for the existing chassis power supply slot. All field wiring connects to the I/O module terminal assemblies, not to the power supply module itself. No wiring changes are required.

Q: Will replacing the power supply affect my C300 controller program or configuration?
No. The FC-IOCHAS-0002R is transparent to the C300 controller logic. The controller’s Experion PKS configuration, control strategies, and FTE network settings are unaffected by a chassis power supply replacement.

Q: Can I hot-swap the FC-IOCHAS-0002R without shutting down the I/O chassis?
Hot-swap is supported on chassis configurations with redundant power supply modules installed. If only a single PSU is fitted, the chassis must be de-energized before replacement. Always consult the Honeywell Experion PKS C300 I/O Installation Guide for your specific chassis revision.

Q: What communication protocols does this module support?
The FC-IOCHAS-0002R is a power supply module and does not directly participate in communication protocols. Communication between the C300 controller and I/O modules is handled via the chassis backplane and the controller’s FTE Ethernet ports. No protocol configuration is required for this replacement.

Q: Is this module compatible with both FC-IOCHAS-0002 and FC-IOCHAS-0004 chassis?
Yes. The FC-IOCHAS-0002R is compatible with both the 2-slot and 4-slot Experion PKS C300 I/O chassis variants. Verify your chassis part number before ordering if you are unsure of your configuration.

Q: How do I verify the module is functioning correctly after installation?
After installation, confirm that the PWR LED on the chassis power supply illuminates green and that all I/O modules in the chassis return to their normal operating state as reported in Experion Station. Check the Experion PKS System Event Log for any chassis power fault alarms that should clear within 60 seconds of a successful replacement.

Warranty Assurance

Every Honeywell FC-IOCHAS-0002R unit supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each unit undergoes a multi-point inspection process including visual inspection for physical damage, connector integrity verification, and functional power output testing where test equipment is available.

If a unit is found to be defective on arrival (DOA) or fails within the warranty period under normal operating conditions, TOPNLMS will arrange a replacement or refund in accordance with our standard after-sales policy. Our technical support team is available to assist with installation queries, compatibility confirmation, and warranty claims via email at [email protected] or by phone at +86 18359293191.

We ship globally from our Xiamen warehouse. Standard lead time for in-stock units is 3–7 business days to most international destinations. Express shipping options are available for urgent plant maintenance requirements. All shipments include tracking and are packaged in anti-static, shock-resistant materials appropriate for sensitive industrial electronics.
