【Help】How can the status feedback values of single-phase electrical equipment be obtained?
Thread Content
As the title suggests, experts, there is a single-phase electrical device that needs to be integrated into the control interlock system. All the other devices are three-phase motors, but one valve operates on 220VAC. The operating status of three-phase motors can be determined by checking whether the contactors are engaged or not. So, how can the operating status of this electric valve be determined?
The electric actuator of the electric valve also provides an output indicating its on/off status
To be precise, it depends on what level of control accuracy you want to achieve! ! Yes, that’s right – it’s the control precision! ! For a weak country, this electric valve is very important and its status needs to be monitored; therefore, it should have a function and mechanism for status feedback, so that feedback signals can be obtained from it. If such a mechanism is not available, then a feedback mechanism should be added or a valve with feedback functionality should be used instead. For a weak country, this valve isn’t that important; its status does need to be monitored. A feedback signal can be obtained from the valve position feedback mechanism and sent to the control center. If there is no such feedback mechanism, a feedback signal can be taken from a contact connected in parallel with the control contactor of the valve. This allows for indirect feedback on the valve’s status, and it represents a low-cost solution; however, its reliability is low – if the valve breaks down or gets stuck, this method cannot provide accurate feedback. So, it depends on the control precision of your operating conditions. There’s definitely a difference in the results between spending money and not spending it! ! Good luck! !
The solenoid valves and motors have been installed on site; they were originally operated manually, but now they start in sequence. By the way, the solenoid valve is connected from the lighting distribution cabinet.
I feel like your description isn’t clear enough regarding how the specific device is used. Do you understand it well?
The valve features indicators for open and closed states, indicators to show when it has reached the open or closed position, and adjustable opening angle.
