( fail freeze function ) Perfect combination with reliable fail freeze function and smart performance with innovative durable coil drive - SS5R (Rotary Type) (Features) ► “Fail Freeze” function to help the valve stay at the last position on the electrical power supply or the pneumatic supply air by accident ► Easy and quick auto-calibration ► Detecting RA (reverse acting) or DA (direct acting) automatically regardless of wrong air connections ► Available to use for single or double acting without any special adjustments ^ Compact design allowing to be installed on small actuators ► Providing error messages against performance failures ► Possible to test the actuator with any fixed signal under a test mode ► Programmable characteristic curve with 17 points ► Wide operating temperature range -30 ~ +80 °C ^ Improved control of high-friction globe and ball valves by eliminating an overshoot and a hunting ► Low air consumption ► Providing a mounting bracket to meet IEC 60534-6-1 for linear valves ► Supporting a NAMUR mounting pattern VDI/VDE 3845 (IEC 60534-6-2) and providing a multi-size mounting bracket for rotary valves (Options) ^ Output position transmitter (4 - 20 mA) ► 2 x alarm limit or micro switch (SPDT) Explosion proof type (IECEx / ATEX / KC Ex ia IIC T6/T5) ► HART communication ► Profibus communication ► Fieldbus Foundation communication (in progress)
Open the catalog to page 1( fail freeze function )(Specifications ) Input Signal ( Principle of Operation ) If 4-20 mA input signal is supplied, the micro processor compares input signal with position feedback and sends control signal to the I/P converting module. Pneumatic signal from the I/P converting module operates the valve and the valve stays at the desired position.
