14 RVM Systems Redundant valve manifold functionality options The RVM System is available in three functionality options, the selection of which will be dependent on the Safety Instrumented Function (SIF) that it is to be used within. 1oo2, 2oo2 double channel and uniquely 2oo3 triple channel systems are available. Compact 1oo2 Semi modular 1oo2 Modular 1oo2 (with bypass) 1oo2 "Safety" Double channel redundant system Redundancy for the process valve closure. Any one out of two solenoid valves needs to de-energise to ensure safety. Compact 2oo2 Semi modular 2oo2 Modular 2oo2 (with bypass) 2oo2 "Availability" Double channel redundant system Redundancy for the process valve to remain open. Any one out of two solenoid valves needs to remain energised to ensure availability. Compact 2oo3 Semi modular 2oo3 Modular 2oo3 (with bypass) 2oo3 "Safety and Availability" Triple channel redundant system Any two channels out of three need to operate to provide safety (process valve closure) and availability (process valve remain open). The RVM system combines the strength of "1oo2" and "2oo2" thus increasing both safety and availability functions.
