1、 Scheme

Explanation: 1. Each power unit is equipped with a wireless module, which is then connected to a cloud server and can be monitored and controlled through computers and mobile devices with external networks. 2. Each power unit must have a wireless antenna.

Application of valve electric actuatorsquarecase

1、 System solution

There are three control methods available: remote control, on-site control, and bus type centralized control.The control module of the electric actuator receives the control signal from the remote control room, and after photoelectric isolation and anti shake processing, it is transmitted to the main controlCPU。 The CPU monitors and collects actuator status signals in real time, controls the motor to drive the controlled valve, and continuously collects valve position signals in real time through high J-degree potentiometers or J-value encoders. Through modern industrial control software algorithms, it achieves precise control of the valve. Simultaneously transmit real-time data to the remote control room. Electric actuator control modulePrinciple *, comprehensive functions, long-term stability and reliability, high integration, low heat generation, easy loading and unloading, and simple maintenance.Can be controlled through an infrared remote controlOr operation panel buttonsPerform non-invasive quick setup on it.

2、 Scheme description and advantages:

1. Comprehensive valve operation status and data monitoring function:

Non invasive design, easy and intuitive debugging;

U ◆ Full view LCD menu display interface: available in both Chinese and English languages;

All kinds of fault information, valve head opening, timely load current, input current signal value, valve head working status, control mode selection, bus function selection, stroke setting and other parameters and states of the valve head can be displayed and set on the LCD screen.

2. Operation of Hall elements inside a four position non through magnetic steel control electrical enclosure

Compared to other knobs or touch controls, it has a beautiful appearance and is easy to operate.

3. Automatic switching function:

The u ◆ series module can switch between three working states: remote automatic/remote manual/on-site;

Remote valve opening and closing signals can receive two effective signals: DC24V and AC220V.

The infrared remote control operation is the same as the on-site operation setting method.

The u ◆ series modules can be freely converted between switch type and adjustable type.

4. Electronic brakes and spark free commutation technology:

The thyristor element controls the output and ensures normal output through software and hardware two-level interlocking.

When using load cut-off, spark free commutation technology is employed.
