ProSafe-SLS, Yokogawa’s solid-state, hardwired safety instrumented systems, is designed to meet the highest safety requirements. This product line meets the requirements of individual safety instrumented system and offers all safety integrity levels (SIL 3-4 for the oil and natural gas, chemical, nuclear, and conventional power industries. The ProSafe-SLS safety system is fully integrated with Yokogawa’s CENTUM VP process controller system and the FAST/TOOLS SCADA program package. ProSafe-SLS safety systems modular design allows for the creation of many applications, including small HIPS systems and large ESD/F&G systems. The system also provides the fastest response time possible to any process demand. The ProSafe-SLS safety instrumented system was created for applications that require the highest Safety Intensity Levels (SIL3 & 4, respectively). It uses solid-state elements for processing the functional logic.
