HIMA F7131 High Reliability DC/DC Converter Module

Description

HIMA F7131 is a high reliability DC/DC converter module that is part of the HIMA F7000 series of safety related automation components. As a critical power infrastructure component, it converts unregulated DC input voltage into stable, isolated DC output, specifically designed for safety controllers, I/O modules, and communication equipment in industrial control systems.

F7131

As part of the HIMA ELOP II platform, F7131seamlessly integrates with fault safety controllers (such as HIMA F7553) to form a redundant power backbone for SIL 3 certification systems. Its main function is to isolate sensitive control electronic components from power fluctuations, EMI, and grounding loops, ensuring deterministic performance in safety critical applications. The dual channel design of this module supports parallel operation to achieve redundancy, and can maintain output even if one channel fails – this is a key feature of 24/7 industrial operations.

For engineers and integrators, HIMA F7131 simplifies power system design by eliminating the need for customized isolation circuits. Its plug and play compatibility with the HIMA ecosystem reduces configuration time, while its built-in diagnostic features (such as output voltage monitoring) support active maintenance. The compact DIN rail installation design of this module also optimizes the space inside the control cabinet, making it suitable for new construction projects and old system renovations.

F7131

Main features and advantages:
HIMA F7131 provides excellent performance through the following core features:
Stable power conversion: With a wide input voltage range (18-36 V DC), the module adjusts the output to precise 5 V DC (± 0.5 V adjustable), ensuring consistent power supply for low-voltage control equipment. Its high efficiency (>90%) reduces heat generation and lowers the need for additional cooling in dense control cabinets.
Robust isolation: Equipped with reinforced isolation barriers (3 kV DC) to protect downstream components from transient overvoltages and ground potential differences, which are crucial in environments with heavy machinery or lightning prone areas. This isolation also complies with the IEC 61508 standard and is suitable for safety related systems.
Redundancy support: The dual channel architecture supports parallel operation or “hot standby” configuration, where each channel is independently powered. If one channel fails, another channel seamlessly takes over, ensuring zero downtime – a feature widely used in offshore platforms and pharmaceutical batch processing systems.
EMC compatibility: Designed to comply with EN 61000-6-2/-6-3 standards, F7131 can withstand high levels of electromagnetic interference and is suitable for installation near variable frequency drives (VFDs) or radio transmitters.
Compact design: The size is only 75 mm x 50 mm x 22 mm, and the module can be installed in cabinets with limited space. It also provides tool free DIN rail installation for quick installation. The front LED indicator light displays power and fault status, simplifying on-site diagnosis.

Application areas:
In liquefied natural gas (LNG) terminals, HIMA F7131 supplies power to emergency shutdown (ESD) valves and fire detection systems, maintaining their functionality even during brief voltage surges caused by compressor start-up.
In pharmaceutical production, this module strictly complies with regulatory requirements, providing stable power to the cleanroom control system to prevent data loss or process interruption caused by voltage spikes. Engineers still rely on this module on the automotive assembly line to support reliable operation of robot safety interlocks and conveyor control systems, reducing downtime caused by power issues.

HIMA F7131 performs well in applications that require fault safe power distribution, such as dual redundant controller setups or remote I/O nodes in distributed control systems (DCS).
In industrial automation, the function of this module is to bridge the gap between unstable input power and sensitive electronic components, ensuring the continuity of safety logic, sensor data, and actuator instructions. By prioritizing stability and electromagnetic compatibility (EMC), this module helps facilities avoid costly safety incidents, production delays, and compliance failures.

Installation and maintenance:
Considerations before installation:
Wiring: Use shielded twisted pair cables for input/output connections to reduce EMI, especially when routing near high-power conductors. Separate the power cable from the signal line to avoid crosstalk.
Grounding: Connect the protective grounding (PE) terminal of the module to a dedicated grounding bus with a grounding resistance of ≤ 4 Ω to ensure EMC compliance and prevent grounding loops.
Redundancy setting: For dual channel applications, configure F7131 in parallel with the same module to ensure balanced input/output connections and avoid load mismatches.
Maintain best practices:
Monthly inspection: visually inspect the terminals for signs of looseness, overheating, or cable damage. Use HIMA engineering tools to monitor output voltage stability and channel health status through diagnostic feedback.
Annual testing: Load testing is conducted by simulating the maximum current load to verify voltage regulation and thermal performance. Replace modules with reduced efficiency (exceeding 5% of nominal output).
Firmware management: Although hardware is the focus, ensure that the firmware of the connected controller is updated to support the diagnostic function of F7131, especially redundancy coordination.
