Tokyo Electron TVB3001-1 Replacement for HPM Series

Product Overview

Tokyo Electron TVB3001-1 Replacement for HPM Series: Seamless Transition from Legacy DCS to Modern Control

The Tokyo Electron TVB3001-1 / STI 3281-000035-19 (internal reference: 1D86-006761-41, HPM5F4F4F6S468) is a critical PCB assembly used within the Honeywell High-Performance Manager (HPM) Distributed Control System platform. As this component reaches end-of-life and original supply channels dry up, facilities running legacy HPM-based process control architectures face increasing pressure to source verified replacements or plan structured migration paths to maintain uptime and regulatory compliance.

TOPNLMS maintains ready-to-ship inventory of this assembly, fully tested and backed by a 12-month warranty. Whether your plant is executing an emergency swap-out or a planned DCS modernization, this page provides the technical context, compatibility guidance, and procurement assurance you need to move forward with confidence.

Seamless Upgrade Solutions

Replacing the TVB3001-1 PCB assembly is rarely an isolated action. In most HPM-based DCS environments, a structured migration involves coordinating several interdependent components to ensure the entire control loop remains stable during and after the swap.

In a typical HPM cabinet, the TVB3001-1 board interfaces directly with the HPM I/O Link module and communicates upstream through the Honeywell UCN (Universal Control Network) coaxial data highway. Facilities that have experienced repeated board failures often find that the root cause lies not in the PCB itself but in degraded HPM power supply modules — particularly the 24 VDC card cage power units — which deliver insufficient or noisy voltage to sensitive logic boards. Replacing the power supply module alongside the TVB3001-1 is a recommended best practice to prevent recurrence.

On the I/O side, the HPM platform uses a range of FTA (Field Termination Assembly) panels and I/O termination modules that connect field wiring to the HPM card cage. These FTAs are wired once and remain in place during a card swap, meaning the TVB3001-1 replacement does not require re-termination of field cables — a significant advantage for minimizing downtime. However, if the FTA itself shows signs of corrosion or contact wear, sourcing a compatible Honeywell HPM FTA replacement at the same time is advisable.

For facilities running Honeywell TDC 3000 or transitioning from older TDC 2000 AM/PM controllers to the HPM platform, the TVB3001-1 assembly is often part of a broader card-level upgrade that also involves HPM High-Performance Process Manager controller boards and associated HPM redundancy modules. Redundancy modules allow hot-standby operation, ensuring that a single board failure does not interrupt process control — a critical requirement in refinery, petrochemical, and pharmaceutical applications.

Communication integrity is equally important. The HPM platform relies on the Honeywell Data Hiway (HW) interface cards and UCN interface modules to maintain real-time data exchange between the HPM and the operator station. If the UCN coaxial cable plant is aging, pairing the TVB3001-1 replacement with a UCN cable inspection and, where necessary, a UCN tap or repeater module replacement will protect the investment in the new board.

Finally, for engineering teams performing the swap without on-site Honeywell support, a Honeywell HPM programming cable and laptop interface kit — compatible with Control Builder software — allows direct board diagnostics, parameter verification, and loop checkout before returning the system to automatic control. This is especially important when the replacement board is sourced from third-party inventory rather than directly from the OEM.

Retrofit Guidance FAQ

Q: Does replacing the TVB3001-1 require re-wiring field terminations?
A: No. The HPM FTA (Field Termination Assembly) remains connected to the card cage via the I/O link cable. The PCB assembly plugs into the backplane slot. Field wiring is not disturbed during a card swap, which is one of the key advantages of the HPM modular architecture.

Q: Will the replacement board require re-programming or re-configuration?
A: For a direct like-for-like swap, no re-programming is required. The HPM controller retains its database in non-volatile memory. After inserting the replacement board, the system performs an automatic download to the new card. Engineering staff should verify loop status and alarm states post-swap using the Honeywell operator station.

Q: Is this board compatible with both simplex and redundant HPM configurations?
A: Yes. The TVB3001-1 / STI 3281-000035-19 assembly is compatible with standard HPM configurations. For redundant HPM setups, both the primary and secondary card slots use the same board type, so this replacement unit can serve either position.

Q: What communication protocols does this board support?
A: The board operates within the Honeywell HPM proprietary communication architecture, including the UCN (Universal Control Network) and the HPM I/O Link bus. No additional protocol converters or gateways are required for a direct replacement.

Q: What are the physical installation requirements?
A: The board occupies a standard HPM card slot within the HPM card cage. No modifications to the chassis, backplane, or cabinet are required. Ensure ESD precautions are followed during handling and insertion.

Q: Can this board be used as a spare/cold standby unit?
A: Yes. Many facilities purchase one or more units as cold standby spares to reduce mean time to repair (MTTR) in the event of future failures. TOPNLMS can supply multiple units from the same tested batch upon request.

Warranty Assurance

Every Tokyo Electron TVB3001-1 / STI 3281-000035-19 PCB assembly shipped by TOPNLMS is subject to a rigorous pre-shipment inspection and functional verification process. Boards are powered up, checked for visible defects, and verified against known-good reference parameters before packaging.

12-Month Warranty Coverage: TOPNLMS provides a 12-month warranty from the date of shipment. If the board exhibits a manufacturing defect or functional failure under normal operating conditions within this period, we will provide a replacement unit or issue a refund, subject to return inspection.

Shipment: Units are dispatched from our Xiamen warehouse. Express international shipping is available via DHL, FedEx, and UPS. Standard lead time for in-stock units is 1–3 business days after payment confirmation. Expedited same-day dispatch is available for urgent requirements — contact us directly to arrange.
