The UK Rotork company launched the intelligent electric actuator (IQ series) in the 190s, which has the following features compared to ordinary actuators:    (1) Convenient remote parameter setting function. Before putting it into operation, the parameter be set remotely by using the dedicated setting tool provided by the manufacturer as long as it is aimed at the actuator. This not only simplifies the setting work procedure but also improves safety of equipment operation, especially in places where explosion prevention is required;    (2) Rich online display function. Using LCD display technology, the built-in LCD display can not only accurately display the valve opening and closing status, normal valve opening, etc., but also display important information when setting parameters or when the actuator has a fault;    (3) Perfect self-diagnosis and protection function. It can diagnose online situations such as servo motor overload, overheating, and the state of the power, etc., and can also automatically identify the phase of the three-phase power supply. In an emergency, the actuator can maintain its position or run to a pre- safe position;    (4) Advanced control function. Adopting computer technology, it designs advanced automatic following control technology as one of its standard functions. The response speed the actuator is proportional to the actual required deviation, which is what is called "speed control", greatly improving the response quality of the actuator;    (5 ）Strong on-site adaptability. The whole machine is designed to have the protection capability of IP54 level, and the ports of the internal and external signals of the actuator adopt optical isolation technology, which improves the reliability, especially the internal control components of the actuator adopt shock-proof fixing methods, and all the connectors are equipped with "anti-osening" to prevent loosening, which makes maintenance very convenient. 

 【Product Name】    IQ Series     

 【Product Introduction】    The electric actu produced by Rotork company are in the leading position in the world in the field of valve control. The IQ series products are the first to adopt infrared setting without opening the cover debugging. The reliable double-sealing structure can dive into the water for 3 meters for 72 hours. Many protection functions make this product a synonym for reliability. 

 【Main Features】     1. Lifetime use: No matter what environment or any application scenario, the IQ's double-sealing waterproof shell and comprehensive protection provide comprehensive protection for the internal components. 2. Simple commissioning: Non-invasive infrared setting is convenient and simple. Users can set and modify parameters quickly and easily.3. Double sealing and double protection: The protection grade is IP68---7 meters underwater for 72 hours, completely waterproof, dustproof, and airtight. . Torque measurement: The patented torque measuring device is advanced in technology and is not affected by frequency, voltage, and temperature changes, which can accurately and repeatedly measure the torque.5. Position measurement: The patented non-contact valve position measuring system makes it extremely simple to accurately position the valve position and easily determine the abnormal change of the end position. . Remote diagnosis: Quick, safe, and non-invasive communication and data exchange can be realized through IrDATM. The data of the actuator can be analyzed and suggestions be given.6.Remote Diagnosis: By using IrDATM to achieve rapid, secure, non-invasive communication and data exchange, it is possible to analyze data of the actuator and provide suggestions.

【Basic Functions】1. Same-phase relay: Automatically corrects phase sequence and phase protection. 2. Overheat protection: A thermal relay within the motor coil can detect coil temperature, and when the temperature exceeds a predetermined value, it can break the control circuit 3. Valve jam protection: If the valve jams, the circuit will automatically break if it does not move within 7 seconds after starting. 4. Instantaneous reversal: An automatic delay circuit processes instantaneous reversal commands to prevent impact. 5. Data recording: Each unit is equipped with a data recorder that can record historical torque, count, status, and date, etc., and can be inquired, analyzed, and diagnosed in real-time. 【Technical Specifications 】1. Local control ). A non-invasive control knob is provided on the electrical box cover, with a red three-state selection switch for local/stop/remote, and a black knob local valve opening or closing electric operation switch. 2). Local control can also be performed within 0.75 meters using the IQ setter for open/close/ operations. 2. Remote switch control 1). Adopt optical isolation interface, usually positive pole switch (can also provide negative pole switch) 2). External user control power supply: Range 20-60V AC/DC or 60-120V AC 3). The actuator internally provides control power: 24V DC 4). The pull-down power supply for each control end: For 24V DC, it is 5mA; for120V AC, it is 12mA 5). The minimum voltage when connected is 20V The maximum voltage when disconnected is 3VThe minimum signal time is 300ms The maximum capacitance between cores of the cable: 2uF 3. Remote analog control 1). Add an board - Proportional control board, users can control with 4-20mA analog quantity. 2). Accuracy: 1% 3). Dead zone Adjustable 0-9.9% within the full stroke 4). Input impedance: 250Ω 5). The input signal can correspond to the position arbitrarily. 4. Output signal 1). Provide four passive, unipolar lockable contacts S1, S2, S3, S4, each contact can set independently by IQ setter to be one of the following signals; each contact can be set to "normally open" or "normally closed", and the contact capacity 5mA-5A 120V AC or 30V DC. a. Valve position Full open, full close position (accurate) or intermediate position (0-99% opening) b. Status The valve is opening, closing, running, selecting local stop, selecting local, selecting remote, starting the or closing valve interlock, starting emergency protection, etc. c. Valve alarm The motor torque jumps off in the travel, the motor torque jumps off in the full or full close position, the actuator is operated by the handwheel. d. Actuator alarm Power phase loss, internal 24V DC missing, battery voltage low, temperature protection jump off. 2). Provide a supervisory relay, which is a passive, reversible independent relay, with a contact capacity of 5mA-5A, 120VAC or 30V DC, and the relay will break in any of the following cases or above: a.
