Intelligent actuator control board, forward and reverse drive intelligent module

SDThe series electric actuator is a terminal control device for industrial process measurement and control systems. It can convert the control signal of the system into the angular displacement of the output shaft to control the position of the valve shut-off component or other regulating mechanisms, so that the controlled medium works according to the system's specified state.

SDThe series of electric actuators have angular travel, multi turn, and linear travel 3 Class of products.

Angular stroke electric actuator used for driving 90 Valves with adjustable angles, such as butterfly valves, ball valves, louvers, dampers, plug valves, baffle valves, etc. Multi turn electric actuators are used to drive gate valves and other regulating valves that require multiple turns of rotation.

Straight stroke electric actuators are used to drive single and double seat regulating valves, sleeve valves, and other regulating valves that require linear displacement.

SDThe series of electric actuators is a series of products developed by absorbing the advantages of national electric actuators and combining them with the actual situation in China.SDThe key components of the series of electric actuators are all imported, and the processing of parts, screening of components, and assembly of the whole machine are strictly carried out in accordance with the process and technical requirements. The testing of the whole machine strictly follows national standards.

SDThe series of electric actuators are safe and reliable, with a wide variety of specifications, high precision, complete functions, light weight, installation, debugging, operation, and maintenanceIt is widely used in industries such as energy, metallurgy, petroleum, light industry, chemical industry, and building materials, and plays an important role in industrial process measurement and control systemsUse it.

Main technical performance

1Debugging menu in both Chinese and English, simple and intuitive.

2, Support 3 Control methods:（All are optocouplers isolated and not afraid of interference）

a)The switch type control can be selected as either jog control or hold control.

b)Analog Control Standard 4-20mAInput signal impedance 100Oh.Output signal impedance<750Ω.（standard configuration）

c)Modbus Bus control, see the following five protocols for specifications.2.4）

3It has the function of phase sequence identification and correction,Three phase electricity does not require phase sequence identification and can operate normally when connected to the device.

4Equipped with power phase loss protection function, the three-phase power phase loss actuator automatically stops and displays a phase loss.

5There are also multiple protective measures:

a)Electronic limit.

b)Over torque protection.

c)There are three options to choose from: signal interruption protection, maintaining the original position, fully closed, and fully open.

d)Motor overheating protection.

e)Blocked rotor protection, when there is a control command, passes through 8SIf there is no feedback action, it is judged as stalling, usually due to an internal circuit fault.6It has one alarm dry contact point, which can be set to select alarm items.

7High precision control with an error of±1%The braking adopts delayed reverse action braking with small current fluctuations.

8HavingESD Emergency control function.

9The highest protection level can reachIP67.
