Azbil Corporation’s Smart ESD Device 700 series (700SIS) is now available. Devices in this series act as the interface for an emergency shutdown valve in a safety instrumented system (SIS). They are compliant with the IEC 61508 international standard for function safety.
The 700SIS has been certified for applications that require Safety Integrity Level (SIL) 2 or 3, according to IEC 61508. It is equipped with the Partial Stroke Test (PST) function for online diagnosis of emergency shutdown valves, a feature that helps to maintain and improve the safety integrity level (SIL) while also reducing the cost of operation and plant design.
Advanced integration of devices utilizing HART® communication is also possible. As a key device in a SIS, the 700SIS is expected to contribute to safe and stable plant operation.
