Foxboro SRD991 Intelligent Valve Control Positioner - Intrinsically Safe (Ex ia). The SRD991 offers the most advanced technology available on the market today. This includes among others an infrared interface for wireless operation and configuration, a multilingual 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 display by the Positioner DTM (VALcare). Moreover, the Positioner DTM enables to edit a complete “health” report of the valve with all data of configuration and diagnostics. The SRD991 has also the capability to control a Partial Stroke Test (PST) that offers operators a tool to identify the trouble proof function of ESD (Emergency Shut Down) valves.
