System compatibility

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

Function

SIL3 8-channel safety relay amplifier module.It receives safety logic command from HIQuad CPU,amplifies low-level safety signal to drive field relay loads,supports independent channel fault diagnosis for wire break and short circuit.When safety trip triggered,module will cut off output to realize fail-safe protection.

Installation

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

Interface

‑8 channels signal output terminals

‑Backplane safety bus connector

‑LED indicators for channel status and fault

Circuit feature

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

Feature

HIQuad series 8-channel SIL3 safety relay amplifier module F3423. Common faults:relay circuit failure,signal channel failure,connector pin failure.Confirm H41q/H51q rack firmware version before replacement.

Diagnostic

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

Built‑in function

F3423 amplifies safety shutdown signals for SIS safety instrumented system emergency shutdown protection,widely used for chemical and power plant safety spare replacement.

Product Brief

F3423 belongs to HIMA HIQuad I/O family,plug-in 8-channel SIL3 safety relay amplifier module for H41q/H51q safety subrack. Verify rack compatibility before ordering. Test signal amplification and fault diagnosis function during commissioning. ESD anti‑static protection shall be followed during installation.
