Foxboro SRI990-BXQR7FAAFDZRZ Positioner
的详细介绍The Analog Positioner SRI990 with analog input 4 to 20 mA is designed to control pneumatic valve actuators. The modular structure of the SRI990 and SRD991 product lines enables conversion from an analog to an “intelligent” positioner with HART or Fieldbus.It offers an easy adjustment by means of switches and potentiometers.For complete specification, refer to Product Specification Sheet PSS EVE0107A-(en).
