Woodward EM-300-24V gear motor actuator set controllers

Woodward EM-300-24V gear motor actuator set controller is a device that converts electrical energy into mechanical energy to drive valves, dampers and other equipment. The following is a related introduction:

Working principle: It is mainly composed of motor, reduction mechanism, controller, etc. When receiving the start signal of the control system, the controller outputs current to the motor, the motor rotates to generate torque, and drives the reduction mechanism to rotate. The reduction mechanism converts the rotational motion of the motor into a motion form suitable for the actuator, such as linear motion or angle adjustment, thereby driving the actuators such as valves and dampers to work. At the same time, detection elements such as position sensors will monitor the position of the actuators in real time and feedback it to the controller to form a closed-loop control to ensure the accuracy of the actuator action.

Functional features:

Various control methods: It can realize full open/full closed valve control, and can also adjust the valve opening proportionally, support PID adjustment, and control by connecting 4-20mA, 0-10V analog signals or digital signals such as Modbus.

Good protection performance: The protection level can reach IP65, can be used outdoors or in humid environments, and can effectively prevent dust and water.

Manual operation function: equipped with a mechanical manual override device, the valve can be manually operated in the event of a power outage, ensuring that the system can still be operated under special circumstances.

High-precision control: with encoder feedback, the resolution can reach ≤0.01°, which can achieve high-precision closed-loop control and ensure that the actuator moves accurately according to the set requirements.

Technical parameters:

Rated voltage: DC 24V.

Output shaft movement form: The output shaft rotation angle is usually ≤90°, suitable for ball valves, butterfly valves, etc.; the output shaft linear movement form can also be provided, suitable for regulating valves, stop valves, etc.

Explosion-proof grade: Optional explosion-proof type, explosion-proof grade can reach EXd II CT6, suitable for flammable and explosive places.

Working temperature range: conventional models are - 20℃~+80℃, special models can work in - 40℃~+200℃ environment.
