F3 D10 20/8 02
F3 DIO 20/8 02
Product Overview
F3 DIO 20/8 02 is a safety-related mixed digital input/output module manufactured by HIMA Paul Hildebrandt for HIMax safety instrumented systems (SIS). It serves as the signal interface between the safety controller and field equipment, collecting binary status signals and executing safety-related switching output commands. Certified to SIL 3 compliance under IEC 61508, this module delivers reliable signal processing for emergency shutdown, burner management and safety interlock loops. Widely implemented in petrochemical plants, power stations and process industry safety control cabinets to guarantee safe operation under abnormal working conditions.
