F 7130A Industrial Power Supply Module (24VDC → 5VDC Conversion)

The F 7130A represents HIMA's commitment to precision power delivery in safety-critical environments. This compact DC-DC converter transforms standard 24-volt industrial bus voltage into stable 5-volt logic power, featuring galvanic isolation that eliminates ground loop interference and multi-layer protection circuitry that safeguards sensitive downstream electronics. Engineered in Germany for process industries where uptime is non-negotiable, this module serves as the backbone power source for distributed I/O racks, safety controllers, and sensor networks across oil refineries, chemical plants, and power generation facilities.

Designed for engineers specifying safety instrumented systems (SIS) to IEC 61508 standards, the F 7130A delivers consistent voltage regulation across wide temperature swings and input fluctuations. Its isolated architecture prevents electrical noise from propagating between field devices and control logic, while built-in current limiting protects against short-circuit damage during maintenance or component failures. Whether you're retrofitting legacy HIMA H51q systems or building new HIMatrix installations, this power module provides the reliability foundation your critical processes demand.

Every unit ships factory-sealed with calibration certificates, ready for immediate integration into your control cabinet. With proven performance in SIL 2/3 applications and compatibility across HIMA's product ecosystem, the F 7130A eliminates guesswork from power supply selection—letting you focus on process optimization rather than troubleshooting voltage sags.

Core Capabilities & Engineering Advantages

→ Precision Voltage Regulation: Maintains 5VDC ±2% across 18-30VDC input range, ensuring stable logic levels for microprocessors and FPGA-based controllers even during supply brownouts or motor start transients.

→ Galvanic Isolation Barrier: 1500VAC isolation rating breaks ground loops between field wiring and control electronics, eliminating common-mode noise that corrupts analog signals in mixed-signal installations.

→ Multi-Stage Protection Architecture: Combines input transient suppression, output overvoltage shutdown, and thermal foldback to protect both the module and connected equipment—reducing mean time to repair (MTTR) by preventing cascading failures.

→ Compact DIN-Rail Form Factor: 22.5mm width conserves valuable panel space in crowded marshalling cabinets, allowing higher I/O density without requiring larger enclosures or additional cooling.

✓ Wide Operating Temperature Range: -25°C to +70°C ambient rating supports installations in unheated equipment shelters, offshore platforms, and desert climates without derating.

✓ Low Ripple & Noise: <50mV peak-to-peak output ripple prevents false triggering of proximity sensors and ensures clean reference voltage for 12-bit/16-bit ADC modules.

Industry Applications & Problem-Solving Scenarios

Emergency Shutdown Systems (ESD): Powers safety PLCs and voting logic in triple-modular redundant (TMR) configurations for oil & gas separation platforms. The isolated design prevents fault propagation between redundant channels, maintaining SIL 3 integrity during partial system failures.

Burner Management Systems (BMS): Supplies stable voltage to flame scanners and ignition controllers in industrial boilers and furnaces. Overvoltage protection prevents UV sensor damage during lightning strikes or switching transients, reducing unplanned shutdowns by 40%.

Turbomachinery Monitoring: Feeds eddy-current proximity probes and accelerometers in compressor vibration monitoring systems. Low-noise output ensures accurate shaft position measurements at 0.1-micron resolution, enabling predictive maintenance before bearing failures occur.

Distributed Control Systems (DCS): Energizes remote I/O racks in chemical batch reactors and pharmaceutical clean rooms. Current limiting protects against wiring faults during installation, while isolation prevents process ground potential differences from corrupting 4-20mA signals.

Redundant Power Architectures: Pairs with secondary F 7130A modules in diode-OR configurations for N+1 redundancy in critical control loops. Automatic load sharing extends module lifespan by reducing thermal stress during normal operation.

Technical Parameters & Selection Criteria

Selection Guidelines: Calculate total 5V load current by summing all connected modules' consumption (typically 200-500mA per I/O card). Add 20% safety margin for inrush current during power-on. For loads exceeding single-module capacity, deploy parallel units with external diode isolation. In SIL 3 applications, always specify redundant supplies with independent input feeds.

Advanced Integration & Customization Options

SCADA Connectivity: While the F 7130A itself lacks communication interfaces, it integrates seamlessly with HIMA F 8628X Ethernet modules and F 8621A coprocessors that provide Modbus TCP, PROFINET, and OPC UA connectivity for remote power monitoring via plant-wide SCADA systems.

Redundancy Configurations: Deploy in hot-standby or load-sharing arrangements using external diode modules. Consult HIMA application note AN-7130-R02 for wiring diagrams and recommended diode specifications (typically 3A Schottky types with <0.5V forward drop).

Custom Voltage Variants: For legacy systems requiring non-standard voltages, HIMA offers factory-customized versions with 3.3VDC, 12VDC, or 15VDC outputs. Minimum order quantities and extended lead times apply—contact our engineering team for feasibility assessment.

Frequently Asked Questions

What is the maximum output current capacity of the F 7130A power supply module?
The F 7130A provides regulated 5VDC output with built-in current limiting to protect against overload conditions. Typical capacity ranges from 2-4A depending on input voltage and ambient temperature. Consult the datasheet or contact our team for load calculations specific to your I/O configuration.

Can this module operate in redundant N+1 power supply configurations?
Yes, the F 7130A fully supports redundant architectures using external diode-OR circuits. For SIL 2/3 applications, we recommend deploying dual modules with independent 24VDC feeds and 3A Schottky diodes (Vf <0.5V) to prevent reverse current flow during single-module failures.

Is the F 7130A compatible with legacy HIMA H51q safety systems?
Absolutely. The F 7130A maintains backward compatibility with H51q, H41q, and all HIMax/HIMatrix platforms. It directly replaces older F 7126 modules with identical mounting footprint and terminal assignments, simplifying retrofit projects without cabinet modifications.

What isolation voltage rating does this power module provide?
The module features 1500VAC galvanic isolation between input and output circuits, tested per IEC 60950 standards. This isolation barrier prevents ground loop currents and protects sensitive logic circuits from field-side transients in installations with multiple grounding points.

Does the F 7130A require external fusing or circuit protection?
While the module includes internal overcurrent protection, we recommend installing a 5A fast-blow fuse on the 24VDC input line per IEC 61010 safety requirements. This provides additional protection against wiring faults and simplifies troubleshooting by isolating the power module from upstream distribution issues.

Can I use this power supply in hazardous area (ATEX/IECSEx) installations?
The F 7130A itself is not intrinsically safe or explosion-proof certified. For Zone 1/2 or Division 1/2 installations, mount the module in a purged/pressurized enclosure rated for the area classification, or use HIMA's dedicated Ex-rated power supplies from the F 71xx-Ex series.
