The introduction of analog and digital technology, integrated chip design, fully Chinese Laidan operation interface, and integrated design concept in IS electric actuators have created their functions and excellent performance. The product has a lightweight appearance, easy debugging, and simple operation. Suitable for complete sets with various types of valves, widely used in control fields such as power, steel, petroleum, chemical, oil pipelines, water treatment, food, etc. IS series is a new generation of valve control expert, which is an intelligent electric actuator used in open-loop control systems. IS is suitable for valves with linear motion of valve discs, such as globe valves, gate valves, throttle valves, diaphragm valves, gates, etc

Characteristics of IS electric actuator:
The highly integrated and non-invasive design adopts large-scale digital integrated chips, with high intelligence, powerful functions, and high control accuracy.
Mechatronics design, lightweight and beautiful. The functions, parameter settings, debugging, and on-site electric operation of the actuator can be set through a handheld infrared remote control without opening the box.

LCD display and on-site operation function:
The IS series actuator adopts a liquid crystal display screen, which allows users to intuitively understand the valve position, operating status, fault alarm and other information of the actuator through visual identification and symbols. The full Chinese menu makes it clear at a glance, and the on-site operation adopts a Hall sensor knob, which can easily perform on-site opening, closing, stopping and on-site/remote control conversion, solving the limit of switch life and making on-site control more accurate and reliable.

Manual/electric switching device:
When manual operation is required, simply press the manual/electric switch handle to the manual position and release it to achieve manual operation. When powered on, the actuator automatically returns to the electric state.

Travel electronic positioning system:
The use of electronic positioning has replaced traditional mechanical limiting, with high accuracy, long lifespan, and high reliability.

Automatic detection and fault diagnosis:
The IS series actuator has a powerful error detection and alarm system, which can detect the operating circuit at any time during operation. Once a fault occurs, the electric operation of the actuator will be prohibited, and local and remote alarm signals will be issued to intuitively display the cause of the fault, allowing users to promptly troubleshoot and restore the normal operation of the actuator.

Fieldbus control:
IS supports communication protocols such as Profibus and Modbus, making it easy to connect to fieldbus control networks. All control and status signals of the actuator can be transmitted through the network, reducing wiring costs. (Note: Standard products do not have bus communication function and are optional accessories)

Travel limit protection function:
Open position, close position, open process, close process, actuator in operation, intermediate limit
Torque limit protection function:
Off torque, on torque, and over torque during travel
Status query function:
Stop/on-site/remote location, on-site open/close/empty space query, whether there is a switch and hold signal in the remote area, whether there is an ESD signal in the remote area, whether there is an automatic control signal in the remote area, whether there is an automatic control current value in the remote area, and whether there is a bus signal
Execution mechanism alarm function:
Power phase loss, motor overheating, loss of proportional control signal, internal malfunction of actuator, over torque alarm, locked rotor alarm, valve steering error, valve position error, presence of ESD signal
Other functions:
Phase sequence automatic correction function, remote control setting function, LCD Chinese display function, on-site control jog/self hold selection function, motor brake function, contact mode selection function, remote dual line control function, dead zone adjustable function, ESD override protection function, main line communication function
