HIMA F‑PWR02 HIQuad X Power Supply Module
Basic Information
F‑PWR02 is an expansion rack power supply module for HIMA HIQuad X system. It is specially designed for power supply scenario of H51X expansion rack, providing regulated power supply and voltage dip buffering capability for backplane I/O modules of expansion rack. F‑PWR02 is not used for the basic main rack, and it is only installed inside the I/O expansion rack of HIQuad X system. It cooperates with F‑PWR01 main power supply module to build the power supply architecture of the complete safety system, meeting IEC61508 SIL3 functional safety level requirements. It is widely used for power supply of expansion units in SIS safety instrumented systems. F‑PWR02 can compensate for input voltage transient dip up to 20ms, preventing shutdown failure of expansion rack modules caused by short‑term voltage disturbance.

Core Advantages
- F‑PWR02 is equipped with reverse polarity protection and automatic‑recovery output short‑circuit protection to reduce hardware damage risk caused by on‑site wiring errors.
- The module integrates complete on‑board diagnosis. Abnormal rack operation can quickly locate fault points via front‑panel indicator lights, cutting down on‑site troubleshooting time.
- Its hardware architecture matches HIQuad X bus protocol. No extra conversion hardware is required; backplane power access is completed by directly inserting into rack slots.
- Fan‑free design eliminates failure points of moving components, improving long‑term operational stability to meet continuous non‑stop operation requirements of petrochemical and oil‑gas sites.
- Unified system status reading is supported via SILworX engineering software to realize remote power supply status monitoring.
Product Features
- Designed exclusively for HIQuad X H51X expansion rack as auxiliary power supply unit for expansion rack; cannot be used as main rack power supply alone.
- Built‑in voltage dip buffer circuit keeps expansion I/O modules running during short‑term grid fluctuation and avoids false triggering of safety interlock.
- Multiple integrated hardware protections: protection triggers under reverse connection, short‑circuit and over‑current conditions, and output recovers automatically after fault removal.
- On‑board hardware diagnostic circuit monitors input and backplane output status in real time; fault signals are reported to controller through system bus.
- Slot‑type modular hot‑swap structure allows independent disassembly and assembly of F‑PWR02 during maintenance without interfering physical wiring of other rack modules.
- Complies with SIL3 functional safety certification; hardware design meets hardware fault‑tolerance requirements for functional safety systems.
Application Fields
- Power supply for expansion rack of SIS Safety Instrumented System in petrochemical industry
- Expansion unit of emergency shutdown system for natural gas pipeline
- Safety control system for boiler combustion protection
- Safety control subsystem for offshore platforms
- Process safety interlock system for pharmaceutical plants
- Turbine protection safety system for power industry
- Safety protection for batch and continuous production in process industry

FAQ
Q: Can F‑PWR02 be directly used on H41X basic rack?
A: No. F‑PWR02 is positioned as auxiliary power supply for H51X expansion rack. Its power rating and pin definition are incompatible with H41X basic rack. F‑PWR01 must be selected for basic main rack.
Q: Can F‑PWR02 act as the main power supply for the whole HIQuad X system independently?
A: It cannot. F‑PWR02 only provides 15W output power and is responsible for backplane power supply of expansion rack only. F‑PWR01 shall be configured for main power supply of the complete system.
Q: What does steady red indicator light of F‑PWR02 stand for?
A: Steady red light indicates module detected fault. Common causes include input voltage out of 19.2‑30VDC range, backplane output short‑circuit or module hardware damage. Check external 24VDC power circuit first, then troubleshoot backplane short‑circuit of rack.
Q: What accessories should be ordered together with F‑PWR02?
A: Only module body is required for regular procurement; racks and terminals are existing system components. Extra external decoupling hardware shall be configured for redundant power architecture.
Q: Does F‑PWR02 support hot‑swap replacement?
A: Hot‑swap is physically supported on slot hardware. Confirm process condition before operation on site. Online plug‑and‑unplug will cause temporary disconnection of I/O of corresponding expansion rack; process safety evasion measures shall be taken.
Q: How to distinguish F‑PWR02 and F‑PWR01 for selection?
A: Choose F‑PWR01 for basic main rack; configure F‑PWR02 for I/O expansion rack equipped with H51X for power supply and buffering of expansion rack. The two modules work in pair.
Q: What are humidity requirements for F‑PWR02 operating environment?
A: Pollution degree 2, no condensation, keep away from corrosive gas. Install inside industrial closed control cabinet, not suitable for open‑air deployment.
Q: Is special parameter configuration required via SILworX for F‑PWR02?
A: The module can be recognized after inserting into rack without special programming. SILworX is only used for reading power diagnostic status of module.
Precautions
F‑PWR02 is only applicable for HIQuad X H51X expansion rack. Verify rack model during model selection; misuse may lead to insufficient power supply or unrecognized module.
External input power must comply with SELV/PELV safety extra‑low‑voltage standard. Long‑term input voltage over 30VDC will cause permanent module damage.
Wiring work must be performed under power‑off status to avoid reverse polarity connection. Although reverse‑connection protection is integrated, long‑term wrong wiring will accelerate hardware aging.
For redundant power supply solution, external decoupling components must be added when F‑PWR02 modules are used in parallel; direct parallel connection is forbidden.
Protection class IP20. Installed inside control cabinet only. Do not expose to dust and moisture directly.
When red fault light appears, troubleshoot external power supply and wiring first. Do not disassemble module privately, as self‑disassembly will invalidate functional safety certification.
