Foxboro SRD960 Intelligent Positioner

Foxboro SRD960 Intelligent Positioner

SRD960 Intelligent Positioner with HART, PROFIBUS PA or FOUNDATION Fieldbus H1 for EEx d Explosion-proof Application

The intelligent positioner SRD960 is designed to control pneumatic valve actuators and is available in the version EEx d (flame-proof)/explosion-proof. It can be operated from any control systems (e.g. the Foxboro I/A Series System).All the diagnostics features can be easily configured and displayed by the Positioner DTM (Valve Monitor). Moreover, the Positioner DTM enables to editing of a complete “health” report of the valve with all configuration data and diagnostics.The positioner is available with HART, Profibus PA or Foundation Fieldbus H1 communication protocols.The SRD960 also has 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.For complete specifications, refer to Product Specification Sheet PSS EVE0109 A-(en).
