The OptiSIS pre-engineered safety instrumented system can help ease deployment and reduce lead times for small and midsized process applications, including those with aging process-safety systems that are either noncompliant or can no longer be maintained. It is designed for safety instrumented system applications of 50 or 100 input/output (I/O) points, including emergency shutdown systems, burner-management systems and high-integrity pressure protection systems. A version for applications of up to 100 I/O points will be available later this year. The pre-engineered system is delivered ready to install, wire and configure, shortening the overall engineering time and eliminating the need for any programming.
