Shipping & Payment

The Honeywell FS-TPSU-2430 is a DC/DC power converter designed for the Honeywell Safety Manager system. It converts a nominal 24 VDC input into an isolated 30 VDC output rated at 1 A. The converter supplies external power to Field Termination Assemblies (FTAs), including analog input assemblies, and provides local voltage indication and relay-based output status monitoring.

Power Conversion and Output Monitoring

The FS-TPSU-2430 provides regulated 30 VDC power from a 24 VDC supply. Its galvanically isolated output separates the incoming supply from the field-side power circuit, supporting the external power requirements of compatible FTA configurations.

The module includes output voltage monitoring, a local LED indicator, and a readback relay contact. When the DC/DC output voltage is within the acceptable range, the LED illuminates and the readback relay contact closes. This allows the system to monitor the availability of the field-side power supply.

FTA Power Distribution

The converter provides six pairs of output terminals for distributing 30 VDC and 0 VDC to external circuits. It is intended for use with Safety Manager FTAs, including the TSAI-1620m and TSHART-1620m analog input assemblies.

The six output connections provide multiple field power termination points. The total output current remains limited to 1 A; the rating is not 1 A per terminal pair.

Electrical Connections

The FS-TPSU-2430 uses screw terminals for incoming power, output distribution, and voltage-status feedback.

Input terminals 3 and 4: 24 VDC IN+ and 24 VDC IN-.
Readback terminals 1 and 2: Relay status contact.
Output terminals 1A-6A: 30 VDC OUT.
Output terminals 1B-6B: 0 VDC OUT, with terminal 6B also designated for the grounding arrangement.

The output-side grounding arrangement must follow the Safety Manager installation requirements. For predictable system behavior under a field-side short-to-earth condition, the 0 VDC output must be connected to ground or a dedicated Earth Leakage Detector (ELD) must be provided for the converter.

Frequently Asked Questions

Q: What is the output voltage and current capacity of the FS-TPSU-2430?

A: It provides a regulated 30 VDC output with a rated current of 1 A. The total current capacity is shared across its six output terminal pairs.

Q: Which Honeywell modules can receive power from the FS-TPSU-2430?

A: The converter is designed to supply other Safety Manager FTAs, including the TSAI-1620m and TSHART-1620m analog input assemblies. The actual power configuration must account for the connected field-device load.

Q: How can the output power status be monitored?

A: The module provides a local LED and a readback relay contact. The LED illuminates and the relay contact closes when the output voltage is OK. The relay contact can be used for external power-status monitoring.
