Overview Model AVP 77../78../79.. is a ..mart ESD (Emergency Shut Down) ..evice that is compatible with the Safety Instrumented Systems (SIS) and the functional safety standard, IEC 61508. It is not only compatible with the ................ 0/24 V DC signal that is used in the safety instrumented systems, but also with 4-20 mA DC and 0-20 mA DC instrumentations. Furthermore, it is equipped with the Partial Stroke Test (PST) by default, and can be utilized with LUI (Local User Interface). Adjustments and settings such as auto setup and zero/span adjustment can also be easily done with the LUI. Features 1. Safety Instrumented Systems (SIS) The device is certified by exida to SIL2 or SIL3 of IEC 61508. 2. Standard Features of PST and FST It is equipped by default with a PST function and Full Stroke Test (FST) feature, and the PST can be automatically implemented based on the equipment's internal schedule..................... In addition, it can also be ..........................the results verified via the LUI (PST only) or ............ommunication tool. .... ............................................
