Honeywell FC-TPSU-2430 V1.1 Replacement for Experion PKS

Product Overview

Honeywell FC-TPSU-2430 V1.1 Replacement for Experion PKS: Seamless DCS Power Supply Upgrade

The Honeywell FC-TPSU-2430 V1.1 is a 24 VDC / 30 W redundant power supply module designed for the Honeywell Experion PKS (Process Knowledge System) and legacy TPS (TotalPlant Solution) distributed control systems. As Honeywell progressively phases out older TPS-era hardware, many facilities running C200, C300, or ACE controller nodes are encountering end-of-life notices on their existing power supply modules. The FC-TPSU-2430 V1.1 serves as the direct replacement and upgrade path, offering backward-compatible form factor, identical rail mounting dimensions, and the same 24 VDC bus interface — allowing engineers to swap the unit without modifying the control cabinet layout or rewiring the field terminal assemblies.

In a typical Experion PKS migration scenario, the power supply module sits within a standard C-series chassis or a Universal I/O (UIO) cabinet, supplying regulated DC power to controller modules such as the C300 Controller, redundant IOTA (I/O Termination Assembly) boards, and associated CHARM I/O modules. When replacing an aging or failed power supply in this architecture, the FC-TPSU-2430 V1.1 slots directly into the existing DIN-rail or chassis bay without requiring a new backplane or modified power distribution wiring. The 24 VDC output is fully compatible with the standard Experion PKS power bus, and the module’s built-in status LED and fault relay output integrate with existing system health monitoring without any firmware changes.

For sites still operating legacy TPS HPM (High-Performance Process Manager) or PM (Process Manager) nodes, the FC-TPSU-2430 V1.1 provides a validated upgrade path. The physical connector pinout and rail voltage specification match the original TPS-era power supply footprint, meaning field wiring to terminal blocks and the cabinet’s AC input distribution panel remains unchanged. Engineers can complete the swap during a planned maintenance window — typically under two hours — without requiring a full system shutdown or PLC program reload. This dramatically reduces downtime risk compared to a full controller migration.

Communication infrastructure within the Experion PKS environment also benefits from a stable, clean power source. Modules such as the FTE (Fault Tolerant Ethernet) switch, EPLCG (Experion PLC Gateway), and Series C Communication Module (CCM) are sensitive to power ripple and transient spikes. The FC-TPSU-2430 V1.1 incorporates active power factor correction and output filtering that meets Honeywell’s internal EMC specifications, ensuring that Ethernet-based controller-to-controller communication and OPC DA/UA data paths remain stable throughout the replacement process.

In retrofit projects where a facility is migrating from a legacy Honeywell TDC 3000 or early Experion R100/R200 architecture to a current Experion R500 or R520 platform, the power supply upgrade is often the first physical step. The FC-TPSU-2430 V1.1 is compatible with both the older LCN (Local Control Network) cabinet power distribution schemes and the newer Experion server-connected I/O cabinets. This cross-generation compatibility makes it a practical stocking item for facilities managing mixed-vintage DCS environments across multiple process units.

For I/O-intensive applications, the module reliably powers dense CHARM I/O assemblies and Series C I/O Link segments without voltage droop under full load. When combined with a redundant power supply pair — a common Experion PKS best practice — the FC-TPSU-2430 V1.1 supports hot-standby switchover, ensuring that a single power supply failure does not interrupt process control. The redundancy relay and load-sharing circuitry are fully compatible with Honeywell’s standard redundant PSU mounting kits, requiring no additional hardware modifications.

From a procurement and project planning perspective, TOPNLMS maintains verified stock of the FC-TPSU-2430 V1.1 with full functional testing completed prior to shipment. Each unit undergoes output voltage verification, load regulation testing, and fault relay continuity checks. Units are shipped with original or equivalent protective packaging, and all shipments include a traceable inspection record. Standard lead time from order confirmation to dispatch is 1–3 business days for in-stock units, with express air freight options available for emergency plant shutdowns.

Seamless Upgrade Solutions

A complete Experion PKS power supply replacement or DCS modernization project rarely involves a single component. In practice, the FC-TPSU-2430 V1.1 is deployed alongside a range of complementary modules to ensure system-wide stability. The Honeywell C300 Controller Module is the most common controller node powered by this supply in current Experion R500/R520 installations, while legacy sites may still be running C200 Controller nodes that share the same power bus architecture. For I/O expansion, CHARM I/O modules and their associated CHARM I/O Termination Assemblies (CIOTA) draw regulated 24 VDC directly from the supply rail, making power quality critical to signal accuracy.

In cabinet-level retrofits, engineers frequently replace the Honeywell FTE (Fault Tolerant Ethernet) switch in the same maintenance window, as aging network switches are a common co-failure point with aging power supplies. The Series C Communication Module (CCM) and EPLCG gateway modules, which bridge Experion PKS to third-party PLC networks via Modbus TCP or PROFIBUS, also benefit from the cleaner power output of the V1.1 revision. For sites performing a broader TPS-to-Experion migration, the Honeywell Universal I/O (UIO) module and Series C I/O Link interface are typically installed in the same project phase, with the FC-TPSU-2430 V1.1 providing the backbone power for the new I/O infrastructure. Finally, for field-level signal conditioning, Honeywell STT850 Smart Temperature Transmitters and STG800 pressure transmitters connected via HART to the new CHARM I/O assemblies complete the end-to-end upgrade picture.

Retrofit Guidance FAQ

Q: Does replacing the FC-TPSU-2430 V1.1 require rewiring field terminals?
A: No. The module uses the same connector pinout and DIN-rail footprint as the original Experion PKS and TPS power supply units. Field terminal wiring and cabinet AC input connections remain unchanged.

Q: Is a controller program reload required after the power supply swap?
A: No. The FC-TPSU-2430 V1.1 is a hardware-only replacement. Controller logic stored in the C200 or C300 module’s non-volatile memory is retained during the swap. A controlled power cycle is recommended post-installation to verify clean startup, but no program download is required.

Q: Is this module compatible with Modbus TCP and PROFIBUS communication segments?
A: Yes. The power supply supports all communication modules within the Experion PKS architecture, including the CCM and EPLCG gateway, which handle Modbus TCP, PROFIBUS DP, and OPC DA/UA protocol bridging. No communication configuration changes are needed.

Q: Will the module fit in the existing cabinet without space modifications?
A: Yes. The FC-TPSU-2430 V1.1 maintains the same physical envelope as the original unit. No cabinet cutouts, additional DIN rail sections, or mounting bracket modifications are required.

Q: Can this module be used in a redundant power supply configuration?
A: Yes. The module supports hot-standby redundancy using Honeywell’s standard redundant PSU mounting kit. Load sharing and automatic failover are supported without additional configuration.

Q: What is the lead time for emergency orders?
A: In-stock units ship within 1–3 business days. Express air freight is available for plant emergency situations. Contact [email protected] or call +86 18359293191 for urgent requirements.
