Valve Positioners SRI990 RCV Analog Positioner DESCRIPTION The SRI990 RCV Analog Positioner with analog input 4…20 mA is designed to operate pneumatic valve actuators. It offers an easy adjustment by means of switches and potentiometers. The modular structure of this positioner series enables conversion from an analog to an “intelligent” positioner by exchanging the electronics. Analog valve control with fast control behavior Easy local operation and adjustments Valve action and rotation configurable by DIP switches Electrical adaptation of zero and span by potentiometers Gain and damping independently adjustable Switch for pneumatic test Easy mounting to all linear and rotary actuators LOCAL OPERATION & CONFIGURATION Housing in Stainless Steel Limit Switches (inductive or Micro switches) Manifolds for gauges and boosters Product Data Sheet
