Foxboro SRD991-BDBD1EA4NR-V01 Positioner

Foxboro SRD991-BDBD1EA4NR-V01 Intelligent Positioner

SRD991-BDBD1EA4NR-V01 Intelligent Positioner with HART, PROFIBUS PA or FOUNDATION Fieldbus H1 for EEx ia Intrinsically Safe Applications

The intelligent positioner SRD991 is designed to control pneumatic valve actuators and is available in the version EEx ia (Intrinsic Safety) and 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 editing a complete “health” report of the valve with all configuration and diagnostics data. The positioner is available with different communication protocols. This includes versions with analog setpoint (4 to 20 mA) and superimposed HART signal; digital with Profibus communication according to PROFIBUS-PA or FOUNDATION fieldbus H1 according to IEC 1158-2 
based on FISCO.The SRD991 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 SheetPSS EVE0105 A-(en) or PSS EVE0105 E-(en).
