System compatibility

Designed for HIMA HIQuad H41q / H51q safety system,collects discrete safety signals from field emergency stop switches,limit switches and safety contact devices,widely used in petrochemical,chemical plant ESD emergency shutdown and F&G fire gas protection system.

Function

SIL3 16-channel safety digital input module.It reads 24V DC contact status from field safety devices,transmits signal data to HIQuad CPU,supports continuous wiring fault diagnosis for wire break and short circuit.The built-in SOE function records event timestamp for fast fault sequence analysis.

Installation

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

Interface

‑16 channels digital input terminals

‑Backplane bus connector for power and data exchange

‑LED indicators for channel status and fault

Circuit feature

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

Feature

HIQuad series 16-channel SIL3 digital input module F3318 with SOE event recording. Common faults:input channel circuit damage,signal acquisition abnormal,connector pin failure.Confirm H41q/H51q rack firmware version before replacement.

Diagnostic

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

Built‑in function

F3318 collects field discrete safety signals and records event sequence for SIS safety instrumented system emergency shutdown and fire protection interlock,widely used for chemical and power plant safety spare replacement.

Product Brief

F3318 belongs to HIMA HIQuad I/O family,plug-in 16-channel SIL3 digital input module with SOE timestamp function for H41q/H51q safety subrack. Verify rack compatibility before ordering. Test signal acquisition and line diagnosis function during commissioning. ESD anti‑static protection shall be followed during installation.
