"ANALOG" (4 to 20 mA):

• Configuration by means of DIP switches and potentiometers

• DIP Switch for pneumatic test

• Pre-configured split ranges

• Easy configuration of direction of rotation

TECHNICAL DATA::

• Analog (4-20 mA):
  Load 300 Ohm
  (6 VDC at 20mA)

• Analog (0-10 V DC):
  4-wire-version, operation by U/I-converter (on request)

• Conversion to intelligent version SRD991  by exchanging the modular electronics (housing,
  air connections and accessories are identical)

COMMON FEATURES:

• Stroke 8 to 260 mm
  (0.3 to 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)

• Low air consumption

• Low vibration effect in all directions

• Single or double-acting

• Mounting on linear actuators directly or according to IEC 534, Part 6 (NAMUR)

• Mounting on rotary actuators according to VDI/VDE 3845

• Protection class IP 65, IP66, NEMA 4X

• Explosion protection:
  • II 2 G EEx ia IIC
    acc. to ATEX
  • “Intrinsic Safety”
    acc. to FM

• Optional built-in independent inductive limit switches in 2-wire or 3-wire technology, or micro switches

• Independent position feedback 4 to 20 mA (integrated on electronic / optional)

The analog Positioner SRI990 with analog input 4-20 mA (or optional with 0-10 VDC) is designed to operate pneumatic valve actuators and is available in the version EEx ia / intrinsically safe and FM.
   The adaptation and settings can easily be achieved by the dip-switches for the action of rotation and the input signal as well as by the potentiometers for the zero, span, gain and damping.
   The functionality can be checked with a pneumatic test executed by a DIP switch.
