System compatibility

Designed for HIMA H41q / H51q HIMax PES safety system,realizes safety data exchange between HIMax safety controller and DCS/PLC,widely used in petrochemical,chemical plant ESD emergency shutdown and F&G fire gas protection system.

Function

SIL3 PROFIBUS DP safety communication module.It serves as PROFIBUS DP gateway for HIMax safety rack,supports master/slave mode,transmits safety status and diagnostic data between safety controller and upper automation system.Built-in communication watchdog continuously monitors bus quality.When bus interruption or communication error detected,the module triggers fault alarm and reports fault to safety controller.

Installation

Plug into H41q/H51q rack backplane,screw PROFIBUS DP cable to 9-pin D-SUB port,configure station address and baud rate via SILworX engineering software.

Interface

‑9-pin D-SUB PROFIBUS DP port

‑Backplane safety bus connector

‑LED indicators for run,fault and communication status

Circuit feature

SIL3 fail-safe communication design,500VAC galvanic isolation,hot-swap support,strong anti-electromagnetic interference,meets SIL3 functional safety requirements for hazardous industrial environment.

Feature

HIMax series SIL3 PROFIBUS DP communication module K7214. Common faults:bus cable damage,D-SUB connector pin oxidation,internal communication chip failure.Confirm system firmware before replacement.

Diagnostic

Bus break,communication timeout or internal hardware fault triggers fault alarm;controller executes safety interlock logic.

Built‑in function

K7214 provides SIL3 PROFIBUS DP data communication for SIS safety instrumented system emergency shutdown protection,widely used for process plant safety spare replacement.

Product Brief

K7214 belongs to HIMA HIMax family,plug-in SIL3 PROFIBUS DP communication module with 9-pin D-SUB interface. Verify rack and firmware compatibility before ordering.Test communication and self-diagnosis function during commissioning. ESD anti‑static protection shall be followed during installation.
