Product Description

Product Description

Intelligent Positioner with HART, PROFIBUS-PA,
FOUNDATION Fieldbus H1 or Without Communication

The intelligent positioner SRD991 is designed to operate pneumatic valve actuators and can be operated from control systems (e.g. the Foxboro I/A Series System), controllers or PC-based configuration- and operational tools
such as FDT/DTM Software. The positioner is available with different communication protocols.

The multi-lingual full text graphical-LCD in connection with the 3 push buttons allows a comfortable and easy local configuration and operation. For installations in contact with explosive atmospheres, certificates are available.

Features and advantages

Easy to operate, menu-driven graphical LCD
Multilingual full text display, visible also with cover closed
All parameters can be configured locally by push buttons
Status and diagnostic messages displayed in LCD
Advanced diagnostics for Valve predictive maintenance
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

APPLICATION

Industrial Automation: Widely used in various industrial systems for precise control of valves, such as in chemical, oil and gas, power generation, pharmaceutical, food and beverage industries, etc. It can control the flow rate of liquids, gases, and other process media, as well as the pressure in hydraulic systems.
Explosive Environments: Due to its explosion-proof certifications (ATEX and FM/CSA), it is suitable for use in hazardous locations with the risk of explosive atmospheres.
Predictive Maintenance Scenarios: With its advanced diagnostics and support for Valcare™ and Valve Monitor DTM, it is conducive to carrying out predictive maintenance in industrial applications, improving the reliability and maintenance efficiency of equipment.
Valve Control in Different Processes: Suitable for both on-off and modulating control of valves in diverse applications, meeting different process control requirements.
