Technical Parameters & Selection Guide

Selection Criteria:

Choose the FC-TPSU-2430 when your application requires isolated 30 VDC power for analog input modules drawing up to 2.5A total. Calculate total FTA current consumption by summing individual module requirements (typically 150-300mA per 8-channel analog input FTA). For systems requiring more than 2.5A, deploy multiple converters with separate output circuits.

Verify input power source can deliver minimum 3.5A at 24 VDC to account for converter losses and inrush current. For redundant power architectures, use external diode isolation modules between parallel converter outputs. Confirm ambient temperature in installation location remains within -40°C to +70°C range, accounting for solar heating in outdoor enclosures.

Extended Functions

Redundant Power Configuration: Deploy dual FC-TPSU-2430 converters with diode-OR output coupling for N+1 redundancy in SIL 2/3 safety applications. Each converter operates at 50% capacity during normal operation, providing automatic failover if one unit fails.

Remote Monitoring Integration: Output voltage and current can be monitored via external measurement circuits connected to SCADA or DCS systems. Implement under-voltage alarms at 28.5 VDC threshold to detect converter degradation before FTA modules are affected.

Customization Options: While the FC-TPSU-2430 is a standard catalog product, custom output voltages (28-32 VDC range) and conformal coating for extreme environments are available for volume orders (MOQ 50 units). Contact technical sales for custom specifications.

System Integration: Pairs seamlessly with Honeywell Safety Manager, Experion PKS, and third-party DCS platforms using standard analog input FTA modules. Compatible with both 2-wire and 4-wire transmitter configurations when used with appropriate FTA terminal blocks.

Frequently Asked Questions

What is the maximum cable length between the FC-TPSU-2430 converter and powered FTA modules?
Recommended maximum cable length is 50 meters using 1.5mm² (16 AWG) wire to maintain voltage drop below 0.5V at 2.5A load. For longer distances up to 100 meters, increase wire size to 2.5mm² (14 AWG) and verify voltage at FTA terminals remains above 29V under full load conditions.

Can this converter power 4-20mA loop-powered transmitters directly?
No, the FC-TPSU-2430 is designed specifically for powering analog input FTA modules, not field transmitters. Loop-powered transmitters receive power from the FTA module's internal loop supply circuits. Use this converter only for FTA module power input terminals.

How do I calculate the required number of converters for my system?
Sum the current consumption of all analog input FTA modules to be powered (check module datasheets for typical values, usually 150-300mA per module). Divide total current by 2.0A (80% of converter capacity for safety margin). Round up to determine the number of converters required. For example, 8 FTA modules at 250mA each = 2000mA total, requiring 1 converter with 20% spare capacity.

What protection features are included against short circuits or overload conditions?
The converter incorporates automatic current limiting at 2.8A (112% of rated capacity) and thermal shutdown protection at 85°C internal temperature. Short circuit protection automatically reduces output voltage to prevent damage, with auto-recovery when fault is cleared. Input reverse polarity protection via series diode prevents damage from miswiring.

Is the FC-TPSU-2430 suitable for marine or offshore platform installations?
Yes, when installed in appropriate enclosures. The converter meets vibration and shock requirements per IEC 60068-2-6 and IEC 60068-2-27, suitable for marine environments. For salt-fog environments, specify conformal coating option (custom order) to protect PCB from corrosion. Ensure enclosure provides minimum IP54 protection for deck-mounted installations.

Can I parallel multiple converters to increase output current capacity?
Direct paralleling without external isolation is not recommended due to potential circulating currents between units. For applications requiring more than 2.5A, use Schottky diode isolation (minimum 5A, 40V rating) on each converter output, or distribute load across multiple converters powering separate FTA groups. Consult factory for parallel operation guidelines.
