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.
- Analog control: Fast response for pneumatic valve actuators via 4–20 mA input.
- Local adjustment: Easy operation using potentiometers and DIP switches.
- Configurable settings: Valve action and rotation adjustable via DIP switches.
- Electrical adaptation: Zero and span adjustable with potentiometers.
- Gain & damping: Independent adjustment for optimal performance.
- Pneumatic test switch: Built-in switch for testing.
- Modular design: Electronics can be upgraded to an intelligent positioner.
- Load: Designed for 300 Ohm load.
- Mounting: Compatible with linear and rotary actuators (IEC 534 Teil 6, NAMUR; VDI/VDE 3845, 3847).
- Rugged construction: Durable for industrial environments.
- Oil & Gas: Exploration, production, transportation, and well testing requiring precise flow measurement.
- Refining, Chemical & Petrochemical: Process monitoring and optimization for safety and regulatory compliance.
- Power Generation: Controls liquid, gas, and steam flow in plants.
- Water/Wastewater: Monitors flow and quality for process control and environmental protection.
- Pulp & Paper: Ensures consistent quality control in production.
