Product Introduction & Supply Chain Strategy
The HIMA F7131 (Part Number: 981713102) is an essential power monitoring and distribution submodule within the HIMA H41q and H51q safety system platform. Responsible for decoupling and feeding steady 24 VDC control power across internal backplane buses, the F7131 ensures clean, noise-free, and fault-isolated energy delivery to central processor modules (e.g., F8650X/F8652X), communication submodules (like the F6706), and internal rack diagnostic circuits.
As mature H41q/H51q control systems continue operating in key energy and processing sites, maintaining New Surplus F7131 modules on-site is critical to continuous operation. Power distribution cards subject to years of continuous thermal load suffer from degraded electrolytic filter capacitors and high-resistance backplane contact pins. Using a factory-fresh, New Surplus F7131 card protects against power brownouts, voltage dips, and spurious process trips across safety instrumented functions (SIF).
Installation & Configuration Guide
1.Stage 1: Pre-Installation Isolation:Prerequisite & Safety.
Follow site LOTO procedures to isolate incoming main 24 VDC supply lines feeding the target H41q/H51q rack. Wear an ESD wrist strap connected to a verified cabinet earth grounding point before handling the replacement F7131 card.
2.Stage 2: Removing the Existing Module:Card Extraction.
Unscrew the upper and lower retaining screws on the front panel of the existing module. Gently pull the ejector handles to release the rear multi-pin connector from the backplane assembly, then pull the card smoothly out along its guide rails.
3.Stage 3: Installing the 981713102:Physical Mounting.
Align the edges of the New Surplus (981713102) with the subrack guide rails. Push the module steadily inward until the backplane connector fully seats. Firmly tighten the top and bottom retaining screws to ensure proper ground bonding and mechanical stability.
4.Stage 4: Power-Up & Voltage Verification:Commissioning & Diagnostics.
Reapply primary 24 VDC power to the rack enclosure. Verify that all front-panel power LEDs illuminate solid green and that no red fault/overcurrent indicators light up. Check ELOP II system diagnostic logs to confirm healthy power status reporting across all monitored channels.
Engineering & Maintenance Notes
- Software Suite Dependency: Maintained and monitored via the HIMA ELOP II engineering programming package.
- Redundancy Management: In dual-redundant power configurations, verify that both redundant modules receive balanced feeder supply voltages to prevent uneven current sharing.
- Backplane Inspection: Prior to inserting the new 981713102 card, inspect the backplane multi-pin receptacle for dust accumulation, physical wear, or damaged pins.

Frequently Asked Questions (FAQ)
What is the exact function of the HIMA 981713102 module?
The is a power supply distribution and monitoring submodule designed to feed and regulate 24 VDC power paths across the backplane of HIMA H41q and H51q safety racks.
Can the be used in newer HIMax or HIMatrix systems?
No. The (981713102) is built specifically for the Eurocard backplane architecture of H41q and H51q systems and cannot be installed in HIMatrix or HIMax racks.
Why is a New Surplus unit preferred over a refurbished power module?
Power submodules carry high continuous electrical and thermal stress. Refurbished cards often retain aged internal capacitors and degraded power traces that can lead to unexpected voltage drops and false trips. A New Surplus unit provides pristine components with full operational lifespan.
What warranty comes with this New Surplus 981713102 card?
Every New Surplus HIMA (981713102) module undergoes comprehensive voltage, continuity, and visual pin inspections, and includes a full 1-year replacement warranty.
