The FS-TPSU-2430 V1.1 is a high-reliability isolated DC/DC power converter module specifically designed for Honeywell's safety management system. It primarily converts the 24 Vdc base power supply in a control cabinet into a highly stable 30 Vdc isolated power supply, providing a comprehensive safety manager for field terminal blocks and process protocols. As a core component of the system, it supports up to SIL 3 safety level and features strong anti-interference capabilities and real-time fault readback monitoring.
SIL3-Level Extreme Safety and Reliability
Superior 1500 Vdc Electrical Isolation and Anti-Interference
Comprehensive Read-Back Relay and Real-Time Self-Diagnostics
The TPSU-2430 module is a DC/DC converter, which provides an isolated 30 Vdc / 1 A to other field termination assemblies (FTAs), such as the analog input FTA modules TSAI-1620m and TSHART-1620m. It has voltage monitoring capabilities with local LED indication and also provides alarm functions (read back relay contact). If the local DC/DC output voltage is OK, the LED is on and the read back relay contact is closed.

Upstream Oil and Gas
Used in Emergency Shutdown Systems on offshore platforms and onshore gas fields to provide 30V isolated power distribution for analog transmitters monitoring wellhead pressure and combustible gases, preventing safety core failures due to external electrical surges.
Petroleum Refining
Operates in Fire and Gas Systems for crude distillation and catalytic cracking units to maintain stable power for flame detector and toxic gas alarm nodes, guaranteeing long-term reliable alarming in harsh refining environments.
Power Generation
Acts as power support for steam turbine overspeed protection and boiler safety monitoring systems, ensuring zero-error transmission of valve position feedback and furnace pressure sensor data.
Urban Rail & Tunnel Safety
Serves as a highly reliable and self-diagnostic power source for remote I/O terminal boards in harsh, humid environments within smoke extraction and emergency escape interlock systems of ultra-long highway/railway tunnels.
Metallurgy & Blast Furnaces
Provides power supply in safety interlocks for blast furnace gas recovery and cooling water interruption protection, maintaining absolute safe operation of signal cards in fields with strong electromagnetic interference and high-temperature environments.
When using the FS-TPSU-2430 V1.1 isolated power converter module, pay attention to the following three points: First, strictly avoid overloading, as its rated output is 30 Vdc/1 A and the total current must be strictly calculated when connecting field termination assemblies (FTAs) and field transmitters . Second, the alarm contact must be closely monitored, ensuring the built-in fault read-back relay contact is wired into the alarm loop of the Safety Manager system to receive alerts immediately if the output becomes abnormal or the LED goes off . Lastly, good ventilation and heat dissipation must be guaranteed, as this high-frequency DC/DC converter generates heat during operation, requiring regular dust cleaning inside the cabinet to prevent accelerated component aging due to overheating.
What is the difference between FS-TPSU-2430 V1.1 and FC-TPSU-2430 CC V1.1?
They are almost identical in electrical function. The primary difference lies in the prefix and coating.
What is the security integrity level of FS-TPSU-2430 V1.1?
As a critical component of a safety management system, it supports up to SIL 3 safety level, suitable for critical life-safety loops such as Emergency Shutdown (ESD) and Fire and Gas (F&G) systems.
How to determine if a module is functioning correctly using the front panel of the FS-TPSU-2430 V1.1?
The module features a status LED on the panel. When the output 30 Vdc is OK, the LED is on and the internal read-back relay contact is closed. If the light goes off, it indicates abnormal output, and the contact will open to trigger a system alarm.
Does the FS-TPSU-2430 V1.1 require daily maintenance?
During routine inspection, check if the panel green LED is on. Also, as a high-frequency DC/DC converter, it generates some heat; thus, good ventilation in the control cabinet must be ensured, and dust accumulation on the vents should be prevented.
What is the connection between the 51401469-100 power supply and FS-TPSU-2430 V1.1?
They belong to different levels or systems within Honeywell. The 51401469-100 is the Node Power Supply for the TDC 3000 control system providing bulk power for rack cards, whereas the FS-TPSU-2430 is an isolated converter power supply in the Safety Manager system, specifically used to distribute isolated power to specific field transmitters and FTAs.
