Versatile Modular Redundancy Architecture for a Safety Instrumented System


Maximizing your ROI through validation, application and training services

As the last line of defense, the safety instrumented system (SIS) must act reliably, exactly when it needs to. Unlike a control system, the SIS must satisfy a number of industry standards to meet this requirement. The SIS must achieve high safety integrity and high system availability. An SIS using Versatile Modular Redundancy (VMR) architecture maintains unlimited SIL 3 operation even under multiple failure scenarios. This reliability by design allows the SIS to continue operating long after safety systems using other architectures would have failed.
