Control Valves
SRI990 RCV Analog Positioner
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.
Features
• 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
• Load 300 ohms
• Easy mounting to all linear and rotary actuators
