Brief description
11AI intelligent electric actuator is the execution unit in the automatic control system. It is powered by power and can accept unified analog or digital standard signals. It is widely used in power stations, chemical industry, petroleum, metallurgy, light industry, building materials, water treatment and other industrial sectors.
Product Overview :
11AI intelligent electric actuators are available in a full range of specifications and adopt a modular structure. Based on the multi-turn type, they can be derived into linear and angular stroke electric actuators with different performances, and can provide users with fast and dual-speed electric actuators. The "A" series electric actuators are suitable for intermittent regulation and can be used as valve regulating devices. The starting frequency is generally 60 times per hour, and the maximum is no more than 600 times per hour. The continuous working time within one hour cannot exceed 15 minutes.

Features :
11AI intelligent electric actuator has manual and automatic control functions, and is equipped with limited stroke and limited torque mechanisms. It is equipped with on-site mechanical opening indication, and has fault alarm and protection functions such as power failure, signal failure, motor overload, and valve jamming. It adopts low inertia and high torque motors and three-phase motors, and can have dynamic braking function (single-phase motors can be used for small-sized actuators). The casing has excellent waterproof and dustproof properties and can provide the power supply DC or AC 24--110V required for external operation. The position transmitter uses DC 24V power supply internally, with high precision and strong anti-interference. It adopts a combined structure and performance components with modular design. Users can choose according to their needs.

Functional modules :
Proportional controller The proportional controller has the function of a general electric actuator servo amplifier, which is equivalent to a positioning controller. It is connected to the actuator and can convert the input continuous current and voltage signals into corresponding position outputs. The proportional controller has the function of preventing oscillation during the actuator adjustment process, signal break protection and dynamic braking. Travel and torque auxiliary switch device: The device includes a potentiometer for continuous remote indication and 6 switches for the end position of the stroke, the intermediate limit switch and the torque limit switch, as well as the on-site mechanical position indicator. CPT position transmitter: Convert the actuator position into DC ON 01OmA, DC 020mA, DC 0~50mA current signal output (the "zero" point is active "zero" and adjustable). Solid-state relay: Enables the actuator to achieve contactless power control. The "A" series Syncropak 1600 electric actuator is an actuator with a more advanced electrical control function. It adds a selection switch for local/break/remote control on the basis of the syncroset type and has multiple functions. Automatic phase correction If the actuator adopts a three-phase motor, no matter how the user connects the three-phase power supply to the actuator, the opening and closing direction of the actuator is unchanged, that is, it can always operate in the correct direction indicated by the controller. Power supply phase loss protection Instantaneous reversing protection Valve stuck motor protection The actuator will disconnect the start release within 7 to 15 seconds after receiving the start signal. If the valve still does not move, the logic circuit will disconnect the start release to provide external operation control power dc24V or ac110V There are 2 auxiliary contacts for external interlocking Can be equipped with additional functional devices The functions of the "M" series electric actuator are similar to those of the "A" series Syncropak1600 electric actuator. The "M" series electric actuator is suitable for continuous adjustment, and the "A" series electric actuator is suitable for intermittent adjustment.
