System compatibility

Designed for HIMA HIQuad X PES safety system,collects field digital safety signals and transmits data to safety controller,widely used in petrochemical,chemical plant ESD emergency shutdown and F&G fire gas protection system.

Function

SIL3 16-channel digital safety input module with 3221/C5 cable connector assembly.It acquires field switch signals including emergency stop,limit switch and valve position feedback and transmits status to HIQuad X safety controller.Each channel supports continuous wire-break and short-circuit diagnosis.When abnormal signal detected,the module triggers fault alarm and sends diagnostic message to safety controller.

Installation

Clip onto standard 35mm DIN rail in control cabinet,complete field sensor wiring via integrated connector,configure channel parameters via SILworX engineering software.

Interface

‑Field signal wiring connector(3221/C5)

‑Internal safety bus connector

‑LED indicators for channel status,run and fault

Circuit feature

Fail-safe safety design,permanent channel diagnosis,galvanic isolation,strong anti-electromagnetic interference,meets SIL3 functional safety requirements for hazardous industrial environment.

Feature

HIQuad X series SIL3 digital input module Z7116/3221/C5. Common faults:connector pin oxidation,cable aging,internal channel circuit damage.Confirm system firmware before replacement.

Diagnostic

Wire break,short circuit or internal hardware fault triggers fault alarm;controller executes safety interlock logic.

Built‑in function

Z7116/3221/C5 collects safety digital signals for SIS safety instrumented system emergency shutdown protection,widely used for process plant safety spare replacement.
