System compatibility

Upgraded A variant of F3226,designed for HIMA HIQuad H41q / H51q safety system.It acquires binary safety signals from hazardous area contact,inductive and optical sensors,widely used in petrochemical,chemical plant ESD emergency shutdown and F&G fire gas protection system.

Function

SIL3 intrinsically safe switching amplifier module.It reads binary signals from hazardous zone field sensors,amplifies and transmits safety signals to HIQuad CPU.Galvanic isolation separates hazardous area and safe control cabinet,supports continuous wire break and short circuit diagnosis for field sensor loops.

Installation

Plug into HIQuad H41q/H51q rack backplane,wire intrinsically safe field sensors to module terminals,complete hardware configuration via ELOPII engineering software.

Interface

‑2 channels binary intrinsically safe input terminals

‑Optocoupler signal output

‑Backplane bus connector for power and data exchange

‑LED indicators for channel status and fault

Circuit feature

1oo2 dual channel fail-safe architecture,intrinsically safe galvanic isolation,periodic hardware self-test,ATEX explosion-proof certification,strong anti-electromagnetic interference,meets SIL3 functional safety requirements for hazardous industrial environment.

Feature

HIMA HIQuad series 2-channel SIL3 Ex i safety switching amplifier F3226A,improved circuit version based on F3226. Common faults:isolation circuit damage,signal transmission abnormal,connector pin failure.Confirm H41q/H51q system firmware before replacement.

Diagnostic

Module or wiring fault triggers fault alarm;controller marks corresponding signal invalid and executes safety interlock logic.

Built‑in function

F3226A acquires binary safety signals from hazardous area field devices for SIS safety instrumented system emergency shutdown and fire protection interlock,widely used for chemical and power plant safety spare replacement.

Product Brief

F3226A belongs to HIMA HIQuad I/O family,plug-in 2-channel SIL3 Ex i intrinsically safe switching amplifier module (A upgraded version). Verify rack and explosion-proof zone requirements before ordering. Test signal acquisition and isolation performance during commissioning. ESD anti‑static protection shall be followed during installation.
