SIL 3 PLC
HiMatrix F35 subsea controller meets the demands of the subsea market for use at up to SIL 3. It uses a HIPPS (High Integrity Pressure Protection System) that monitors excess wellhead pressure and partially isolates pipe pressure by closing off effected pipeline segments. HIPPS can be used at depths to 4,000 m and is built to IEC 61508/SIL 3 and ISO/DIS 13628-6 (Control systems for underwater production). HiMatrix controllers are connected via safeethernet, and the link to the SEM (Subsea Electronic Module) is made through Modbus RTU.
