Valve Positioners SRD991 RCV Intelligent Valve Positioner DESCRIPTION The SRD991 Intelligent Valve Positioner offers the most advanced technology available on the market today. The technology includes, among others, an infrared interface for wireless operation and configuration, a multi-lingual full-text graphic LCD and an availability with the choice of all in the process automation applied communication protocols. It offers enhanced applications and methods to analyze recorded stroke data. All the diagnostics features can be easily configured and displayed by the Positioner DTM (VALcare). Moreover, the Positioner DTM enables editing a complete health report of the valve with all data of configuration and diagnostics. The SRD991 also has the capability to control a Partial Stroke Test (PST) that offers operators a tool to identify the trouble-free function of ESD (Emergency Shut Down) valves. Easy to operate, menu-driven with graphical LCD Multilingual full text display, backlighted for easy reading All parameters can be configured locally by push buttons Status and diagnostic messages displayed in LCD Advanced diagnostics for valve predictive maintenance Premium diagnostics for valve signatures, online friction Suitable for safety applications up to SIL 3 Partial stroke test (PST) for emergency shutdown applications HART Protocol with only 420 Ohms load PROFIBUS-PA acc. to IEC 1158-2 based on FISCO FOUNDATION Fieldbus H1 acc. to IEC 1158-2 based on FISCO with PID, AO, 2xDI, DO function blocks and LAS functionality Infrared interface for wireless communication Easy mounting to all linear and rotary actuators Diagnosis Report Stainless steel housing Limit switches or position transmitter Gauge manifolds and volume boosters Pressure sensors for supply air and outputs Product Data Sheet
