Fieldbus Interface Solution – Honeywell DC-TFB402 | TotalPlant Solution Series
The Honeywell DC-TFB402 (P/N 51307616-176) is a Fieldbus Interface Module designed for the TotalPlant Solution (TPS) Distributed Control System platform. It provides a reliable, high-integrity communication bridge between field devices and the process control network in demanding industrial environments.
Where This Product Is Used
The DC-TFB402 is deployed across a wide range of process industries where Foundation Fieldbus or high-speed field device communication is critical:
- Oil & Gas Refineries – Integrating flow transmitters, pressure sensors, and control valves on fieldbus segments in upstream and downstream processes.
- Chemical & Petrochemical Plants – Managing multi-drop fieldbus loops for reactor monitoring, distillation column control, and safety instrumented systems.
- Power Generation – Connecting boiler instrumentation and turbine control devices to the TPS DCS backbone.
- Pulp & Paper Mills – Coordinating fieldbus segments across wet-end and dry-end process areas.
- Pharmaceutical Manufacturing – Supporting validated control architectures where device-level diagnostics and data integrity are mandatory.
- Water & Wastewater Treatment – Enabling remote I/O and fieldbus communication in distributed pump and valve control stations.

Why Engineers Specify This Model
- Platform-native compatibility – Engineered specifically for the Honeywell TPS architecture, eliminating integration risk associated with third-party fieldbus gateways.
- Deterministic communication – Supports scheduled and unscheduled communication modes, ensuring time-critical process data arrives with predictable latency.
- Diagnostic transparency – Exposes device-level diagnostics (valve signatures, transmitter health) directly to the TPS operator station without additional middleware.
- Redundancy support – Compatible with redundant fieldbus segment configurations for high-availability process loops.
- Long service life – Honeywell TPS hardware is designed for 20+ year plant lifecycles; sourcing genuine modules preserves system warranty and support agreements.
- Reduced wiring cost – Multi-drop fieldbus topology supported by the DC-TFB402 can reduce field wiring by up to 70% versus conventional 4–20 mA point-to-point wiring.

Application-Specific FAQ
Q: Is the DC-TFB402 compatible with Honeywell Experion PKS?
A: The DC-TFB402 is native to the TPS platform. Experion PKS uses a different fieldbus interface architecture (FIM4/FIM8). Cross-platform use requires engineering validation — contact us for guidance.
Q: Can this module be used in a redundant fieldbus configuration?
A: Yes. The DC-TFB402 supports redundant H1 segment configurations when paired with the appropriate Honeywell redundancy hardware and TPS software release.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–6 week lead time depending on sourcing. Contact us for real-time availability.
Q: Do you provide a warranty?
A: Yes. Konmask.com offers a 12-month warranty on all tested modules. See our warranty policy for full terms.
Q: Can you supply the full TPS system or just individual modules?
A: We supply both individual modules and complete TPS system assemblies. Contact us with your full BOM for a consolidated quote.
