HIMA F8651E H41q/H51q CPU Module

Product Description

F8651E is the central CPU module of HIMA H41q / H51q safety control system, with single processor architecture. It acts as the main controller for safety logic calculation, I/O scheduling, communication exchange and self-diagnosis. It can work with redundant CPU to build SIS safety instrumented systems. The module is equipped with comprehensive internal fault diagnosis, reports fault status rapidly, supports backplane hot-swap installation, and is widely deployed for ESD, F&G and BMS safety protection loops in petrochemical, power and other industries.
