Product Description Product DescriptionIn the realm of industrial automation and process control, precise valve control is of utmost importance. Foxboro, a renowned name in the field, offers a range of intelligent valve positioners, with the SRD991, SRD998, and SRD990 being prime examples. These positioners are designed to meet the diverse and demanding requirements of various industries, ensuring reliable and efficient operation. The Foxboro SRD991 is engineered for the precise control of pneumatic valve actuators. Its design allows for versatile configuration, which can be carried out either locally or remotely. This flexibility is crucial in different industrial setups, where access to the positioner might vary. For instance, in large industrial plants, remote configuration can save significant time and effort.One of the standout features of the SRD991 is its compatibility with multiple communication protocols. It supports HART, Fox Com, PROFIBUS - PA, and Foundation Fieldbus H1. This wide range of protocol support enables seamless integration with different control systems. In a modern industrial environment, where different devices from various manufacturers need to work together, the ability to communicate via multiple protocols is a major advantage. For example, in a chemical plant with a complex control system, the SRD991 can easily interface with other devices using the appropriate protocol.FeaturesThe SRD991 comes with intelligent self - calibration capabilities. It has an auto - start function that includes self - calibration, ensuring that the positioner is always in optimal working condition. Additionally, it offers comprehensive diagnostics. The Valcare? and Valve Monitor DTM (Device Type Manager) provide predictive maintenance tools. This is highly beneficial in industrial applications as it allows for the early detection of potential issues, reducing unplanned downtime. For example, by continuously monitoring the valve's performance, the diagnostics can identify if a component is starting to wear out, giving maintenance teams time to plan and replace the part before a failure occurs.The user interface of the SRD991 is user - friendly, featuring a multi - lingual graphical LCD with three - key navigation. This makes it easy for operators to configure the positioner and access important information, regardless of their location or language. Even in regions where English may not be the primary language, operators can easily understand and interact with the positioner. Product OverviewIt can handle a wide operational range. Stroke lengths can vary from 8 to 260 mm, and angle ranges can go up to 95°, with the option to extend it to 300° upon request. This adaptability makes it suitable for a variety of valves and applications. Whether it's a small - scale valve in a laboratory setting or a large - scale industrial valve in a refinery, the SRD991 can be configured to operate effectively.The SRD991 is compatible with linear actuators (NAMUR) and rotary actuators (VDI/VDE), providing multiple mounting options. It also offers high - level protection. Rated IP65 as standard, with the option for IP66 and NEMA 4X, it can withstand harsh environmental conditions. In industries such as oil and gas, where equipment is often exposed to dust, water, and corrosive substances, this level of protection ensures the long - term reliability of the positioner.The Foxboro SRD998 is an advanced intelligent control valve positioner. Its modular design is a key feature that sets it apart. This design not only reduces maintenance and spare part costs but also allows for easy customization. With a single user - dedicated compartment for cabling and configuration, it simplifies the installation and maintenance process.The SRD998 offers high - performance capabilities. It can support high air supply and output pressures up to 10 bars. This high - pressure capability allows for greater torque on actuators, which in turn means that smaller actuator sizes can be used in some applications. This is beneficial in terms of cost - effectiveness and space - saving. For example, in a compact industrial facility where space is limited, the ability to use smaller actuators without sacrificing performance is a significant advantage.Product ParametersModelSRD991ModelSRD998Control ModeSingle or double actingControl ModeSingle or double actingCommunication ProtocolHART, PROFIBUS - PA, FOUNDATION Fieldbus H1Communication ProtocolHARTSupply Air PressureUp to 6 bar, extendable to 7 bar with a spool valveSupply Air PressureUp to 10 barStroke Length8 to 260 mmStroke Length8 to 260 mmAngle RangeUp to 95° (extendable to 300° on request)Angle RangeUp to 95° (up to 120° on request)Mounting StandardLinear actuators (NAMUR), rotary actuators (VDI/VDE)Mounting StandardOnto any linear or rotary actuatorProtection LevelIP65, optionally IP66, NEMA 4XProtection LevelIP66, NEMA 4XSafety CertificationSIL applications, ATEX, FM/CSAr intrinsic safetySafety CertificationATEX, IECEx, INMETRO, NEPSI, etc. intrinsic safetyInput Signal4 - 20 mAInput Signal4 - 20 mA or 1 - 5 VDC (selectable)Self - calibrationYesSelf - calibrationYesDiagnostic FunctionVia Valcare? and Valve Monitor DTMDiagnostic FunctionVia Valcare?
