Rockwell speeds deployment of safety instrumented systems
21 June 2015
Rockwell Automation has introduced OptiSIS, a pre-engineered safety instrumented system that can help ease deployment and reduce lead times for small and mid-sized process applications.
OptiSIS is designed for safety instrumented system applications of 50 or 100 I/O points, including emergency shutdown (ESD) systems, burner-management systems (BMS) and high-integrity pressure protection systems (HIPPS).
The pre-engineered system is delivered ready to install, wire and configure, shortening the overall engineering time and eliminating the need for any programming. Users need only enter their logic sequences into the system’s cause-and-effect graphical interface. The configurations are tested and can then be stored for verification against original safety function requirements – or used at a later date to restore the system to a known state.
Flexible inputs and outputs help confirm that the system accommodates a varying mix of digital and analogue I/O types. Additionally, simplex I/O and fault-tolerant (dual) I/O versions are available to address different redundancy needs.
The system meets requirements up to Safety Integrity Level 3 (SIL 3) and is compliant with IEC 61511/ISA 84.00.01. It uses ready-to-install, TUV-certified hardware and validated application software.
