Specifications: 7M
Category : Actuator – Electric actuator
Brand : Shanghai Automation Intrument
The “M” and “A” series 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 “M” series electric actuators are suitable for occasions of continuous and frequent adjustment, and their adjustment frequency can reach 1200 times per hour. The “A” series electric actuators are suitable for occasions of intermittent adjustment and can be used as valve adjustment devices.
Their starting frequency is generally 60 times per hour, and no more than 600 times per hour at most. The continuous working time within one hour cannot exceed 15 minutes. The “M” and “A” series electric actuators are the execution units in the automatic adjustment control system. They are powered by power supply and can accept unified analog or digital standard signals. They are widely used in industrial sectors such as power stations, chemicals, petroleum, metallurgy, light industry, building materials, and water treatment.
Product features:
It has manual and automatic control functions, and is equipped with travel and torque limit mechanisms. It is equipped with on-site mechanical opening indication. It has fault alarms and protection functions such as power failure, signal failure, motor overload, and valve jam. It uses a low-inertia and high-torque motor. It uses a three-phase motor and can have a dynamic braking function (a single-phase motor can be used for small-size actuators). The housing has excellent waterproof and dustproof properties and can provide the power required for external operation. The position transmitter uses a DC 24V power supply with high accuracy and strong anti-interference. It adopts a combined structure and performance components with modular design. Users can choose any one according to their needs. Functional module 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 failure protection and dynamic braking functions. Travel and torque auxiliary switch device: The device includes a potentiometer for continuous remote indication and 6 only for the end position of the stroke, the intermediate limit switch and the torque limit switch, as well as an on-site mechanical position indicator. CPT position transmitter: converts the actuator position into DC ON 0～10mA, DC 0～20mA, DC 0～50mA current signal output (“zero” point is active “zero” point, 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 complete electrical control function. It adds a local/off/remote control selection switch 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 phase loss protection Instantaneous reversing protection Valve stuck Motor protection Actuator If the valve still does not move within 7 to 15 seconds after receiving the start signal, 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.
