Profile:
HART EDD Only
More Information:
Single-acting or double-acting positioner for attachment to pneumatic control valves. Self-calibrating, automatic adaptation to valve and actuator.
Special features:
– Simple attachment to all common linear and rotary actuators
– Simple single-knob, menu-driven operation
– LCD easy to read in any mounting position thanks to selectable reading direction
– Configurable with a computer over the SSP interface
– Variable, automatic start-up with four different initialization modes
– Travel sensor without gears susceptible to wear
– Sub (substitution) initialization mode allows the positioner to be started up in case of emergency whilst the plant is running without having to change the valve position.
– All parameters saved in non-volatile EEPROM
– Adjustable output pressure limitation
– Adjustable tight-closing function
– Continuous zero point monitoring
– Integrated temperature sensor and operating hours counter
– Two programmable position alarms as standard
– Self-diagnostics; alarms as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter
– Integrated diagnostics for control valves
– Pressure sensors to monitor the supply air and signal pressure
