System compatibility

Designed for HIMA HIQuad H41q / H51q safety system,used for field safety trip circuit control,widely used in petrochemical,chemical plant ESD emergency shutdown and F&G fire gas protection system.

Function

SIL3 8-channel safety relay output module.It receives safety shutdown commands from HIQuad controller,uses relay normally open floating contact to switch field safety circuits,built-in periodic hardware self-test.In safety trip condition,the relay contact will switch to safe state to realize fail-safe shutdown.

Installation

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

Interface

‑8 channels relay contact terminals

‑Backplane safety bus connector

‑LED indicators for channel status and fault

Circuit feature

1oo2 fail-safe safety architecture,periodic hardware self-test,strong anti-electromagnetic interference,meets SIL3 functional safety requirements for hazardous industrial environment.

Feature

HIQuad series SIL3 8-channel relay output module F3422. Common faults:relay contact aging,internal circuit failure,connector pin failure.Confirm H41q/H51q rack firmware version before replacement.

Diagnostic

Module or wiring fault triggers alarm;controller executes safety trip interlock logic.

Built‑in function

F3422 provides relay contact switching commands for SIS safety instrumented system emergency shutdown protection,widely used for chemical and power plant safety spare replacement.

Product Brief

F3422 belongs to HIMA HIQuad I/O family,plug-in SIL3 8-channel relay output module for H41q/H51q safety subrack. Verify rack compatibility before ordering. Test relay action and diagnosis function during commissioning. ESD anti‑static protection shall be followed during installation.
