Smart Valve Positioner ( fall freeze function ) SS5 linear / Rotary Perfect combination with reliable fail freeze function and smart performance with innovative durable coil drive ► “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 VDIA/DE 3845 (IEC 60534-6-2) and providing a multi-size mounting bracket for rotary valves ^ Output position transmitter (4 - 20 mA) ► 2 x alarm limit or micro switch (SPDT) ► Explosion proof type (lECEx / ATEX / KC Ex ia IIC T6/T5 - in progress) ► HART communication ► Profibus communication (in progress) ► Fieldbus Foundation communication (in progress)

( fail freeze function )(Specifications ) Input Signal ( Principle of Operation ( If 4-20mA input signal is supplied, the microprocessor compares the input signals and the feedback values and send the control signals to the I/P converter. A supply air is converted to the pneumatic signals by two electronic coils and moves the pilot valve until the control valve reaches the desired position. In case of a signal failure or a supply air failure, a venting air is blocked inside of the pilot valve and the valve stays at the last position because of an existing supply air pressure between the...
