    Repair and maintenance operations must be carried out by qualified personnel!

    SRD991 Intelligent Positioner All Versions

    The intelligent positioner SRD991 is designed to operate pneumatic valve actuators and can be operated fromcontrol systems (e.g. the Foxboro I/A Series System), controllers or PC-based configuration- and operational toolssuch as PC20 / IFDC or PC50 (FDT 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 localconfiguration and operation as well as the display of valve specific data, and status- and diagnostic messages.

    DEVICE FEATURES

    Intelligent Auto-start with self-calibration Self diagnostics, status- and diagnostic messages Easy operation with three keys Multi-Lingual full text graphical LCD, or LEDs

    with communication HART, FOUNDATION Fieldbus H1,

    PROFIBUS-PA, FoxCom Configuration by means of local keys, hand-

    held terminal (HART), PC or I/A Series systemor with a infrared interface by means of IRCOM

    without communication Input signal 4 to 20 mA

    COMMON FEATURES

    Stroke 8 to 120 mm / 260 mm (0.3 to 4.7 in / 10.2 in) Angle range up to 95 Supply air pressure up to 6 bar (90 psig),

    with spool valve up to 7 bar (105 psig)

    Single or double-acting Mounting on linear actuators according to NAMUR

    IEC 534, Part 6 VDI/VDE 3847

    Mounting on rotary actuators acc. to VDI/VDE 3845 Protection class IP 65, NEMA 4X Explosion protection: Intrinsic safety according

    to ATEX and FM/CSA
