HIMA F8652X 98486526X Safety Central CPU Module for H41q‑H51q PES System

Product Description

F8652X (984865265) is the central safety‑related CPU module for HIMA H41q‑H51q programmable electronic safety system(PES). It adopts dual clock‑synchronized processor architecture, 

executes safety interlock logic, sequence control and system fault diagnosis for SIS. It communicates with I/O modules via backplane bus, provides serial interfaces for engineering download 

and upper‑system data exchange. Complies with IEC61508 SIL3 safety standard. It is widely used in petrochemical, oil‑gas, power‑plant ESD, F&G safety instrumented cabinets.
