Overview Manuals Specifications Application Scenarios Protection Installation

Features:

  • Continuous supervision of 5 V DC system voltage from up to three power supplies with stable monitoring performance.
  • Integrated diagnostic interface with 3 test bits for F 8650 / F 8651 modules enabling system-level status evaluation.
  • Compact 4 TE design combined with LED-based status indication and low operating current for efficient cabinet integration.
HIMA F7131 plays an important role in maintaining stable voltage supervision across industrial automation systems where multiple power supplies are used. By monitoring the 5 V DC system voltage from up to three sources, HIMA F7131 helps ensure that control processes remain uninterrupted under varying load conditions. The module HIMA F7131 also provides clear visual feedback through LED indicators, allowing operators to quickly assess system health during daily operation.

In addition to voltage supervision, HIMA F7131 integrates diagnostic communication through dedicated test bits compatible with F 8650 and F 8651 central modules. This allows HIMA F7131 to participate directly in system diagnostics and user-programmed monitoring logic, improving overall transparency of power distribution behavior. The inclusion of 3 × 24 V DC outputs further extends its monitoring capability to external power supply configurations, making HIMA F7131 suitable for modular and scalable system designs.

From an installation perspective, HIMA F7131 is engineered for compact control cabinets with a space requirement of only 4 TE. Its low current consumption and structured monitoring approach make HIMA F7131 suitable for continuous operation in demanding industrial environments. The buffer battery system further enhances reliability, supporting long-term operation and reducing maintenance frequency in critical automation infrastructures.

The F7131 HIMA Power Supply Monitoring Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer HIMA
  • Model F7131
  • Condition New Original ready stock
  • Product Family F7130A,F7133,F7130
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Safety Instrumented System (SIS): Deployed in H41q/H51q redundant control cabinets, providing triple redundancy diagnostics for the primary and backup core CPU power supplies.
  • Fire Gas Monitoring (F&G): In large petrochemical tank farm fire detection mainframes, responsible for real-time monitoring of the health of the audible and visual alarm loops and the core power supply box.
  • Emergency Shutdown System (ESD): Applied to the linkage controllers of critical valves on offshore drilling platforms and oil pipelines, ensuring the power supply safety of the logic processing unit.
  • Burner Management System (BMS): Used in the ignition control boxes of large power plant boilers for centralized polling monitoring of multiple 24V DC auxiliary actuator power supplies.
  • Undervoltage Latch Protection: When the system's 5V core operating voltage drops below the safe threshold, the module immediately locks the fault state and sends an interrupt signal to the CPU.
  • Battery Reverse Connection Protection: Built-in hardware foolproof and reverse polarity protection circuitry at the battery input terminal effectively prevents damage to the board or battery due to maintenance errors.
  • Signal Isolation Protection: All external 24V monitoring input terminals are opto-isolated from the core processor to prevent external power surges from entering the main control system.
  • Power-Off Overcharge Protection: At the moment the system's main power supply is completely disconnected, internal energy storage components and a buffer battery suppress logic misjudgments caused by level fluctuations.
  • Slot Orientation and Tightening: The module uses a rack-mount slot physical guide design. After pushing it into position, the two original knurled fixing bolts must be tightened.
  • Battery Tab Activation: Before initial power-on installation or replacement of spare parts, the CR-1/2 AA backup battery must be correctly connected according to the markings, and the insulating sheet must be removed.
  • Hot Maintenance Safety Limitations: While mechanical plug-in/out is supported, blindly performing hot-plugging operations is strictly prohibited in high-risk control loops (such as ESD activation states).
  • Grounding Loop Verification: During rack mounting, ensure good contact between the board's metal contacts and the base grounding busbar to maintain the module's anti-static shielding.
Description
HIMA F7131 functions as a dedicated monitoring unit for system voltage supervision in safety-related automation environments. It continuously checks the 5 V DC supply generated by up to three power supplies, ensuring stable operation of connected control systems. The module HIMA F7131 uses three front-panel LED indicators to clearly display power status, helping operators quickly identify supply conditions during operation.

The diagnostic capability of HIMA F7131 is enhanced through three test bits designed for central modules F 8650 and F 8651. These signals enable system-level diagnostic display and integration into user programs, improving transparency of power conditions within the control architecture. In addition, HIMA F7131 supports three 24 V DC monitoring outputs (PS1 to PS3), which allow supervision of external power supply units, including those in additional power supply assemblies such as assembly kit B 9361.

From an operational standpoint, HIMA F7131 maintains low power consumption with 5 V DC at 25 mA and 24 V DC at 20 mA. It is designed with a compact footprint of 4 TE, making it suitable for dense cabinet installations. The buffer battery used in HIMA F7131 supports long service intervals, offering up to 1000 days at 25 °C and 200 days at 60 °C, with a recommended replacement cycle of up to six years under operating conditions.
