System compatibility

Special variant version of F3348,designed for HIMA HIQuad H41q / H51q safety system,output safety control signals for field solenoid valves,alarm relays and safety actuators,widely used in petrochemical,chemical plant ESD emergency shutdown and F&G fire gas protection system.

Function

SIL3 8-channel safety digital output module.It receives safety logic command from HIQuad CPU,outputs 48V DC control signal to field safety equipment,supports continuous wiring fault diagnosis for wire break,short circuit and overload.When safety trip triggered,module will cut off output to realize fail-safe protection.

Installation

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

Interface

‑8 channels digital output 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 overcurrent protection,strong anti-electromagnetic interference,meets SIL3 functional safety requirements for hazardous industrial environment.

Feature

HIQuad series special variant 8-channel SIL3 48V DC digital output module F334838. Common faults:output channel burnout,overcurrent damage,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

F334838 outputs safety control signals for SIS safety instrumented system emergency shutdown and fire protection interlock,widely used for chemical and power plant safety spare replacement.

Product Brief
