System compatibility

Designed for HIMA HIQuad H41q / H51q safety system,used for relay signal amplification of safety shutdown circuits,widely used in petrochemical,chemical plant ESD emergency shutdown and F&G fire gas protection system.

Function

SIL3 4-channel safety relay amplifier module.It receives safety trip signals from HIQuad CPU and amplifies the signal to drive field safety relays,supports continuous wire break and short circuit diagnosis for each field loop.In case of safety trip or loop fault,the module will cut off output safely to achieve fail-safe protection.

Installation

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

Interface

‑4 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 4-channel SIL3 safety relay amplifier module F3405. Common faults:internal circuit damage,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

F3405 amplifies safety relay signals for SIS safety instrumented system emergency shutdown protection,widely used for chemical and power plant safety spare replacement.

Product Brief

F3405 belongs to HIMA HIQuad I/O family,plug-in SIL3 safety relay amplifier module for H41q/H51q safety subrack. Verify rack compatibility before ordering. Test signal output and fault diagnosis function during commissioning. ESD anti‑static protection shall be followed during installation.
