1. HIMA F8640 Overview
HIMA F8640 is an industrial safety I/O module launched by HIMA Paul Hildebrandt GmbH, a globally leading provider of safety technology. HIMA specializes in delivering Functional Safety Systems for high-risk industries such as chemical, energy, and pharmaceutical. As an I/O expansion module, the F8640 is typically used in conjunction with HIMA’s main controllers (e.g., CPU modules).
This module is mainly designed to collect on-site signals (such as sensor signals and digital signals) and transmit them to the main control system. Meanwhile, it is equipped with the function of executing safe output, ensuring that the system can quickly trigger safety measures when abnormalities are detected.
