Introduction to Sinamics Converters

With SINAMICS frequency converter technology converts 0-10mA or 4-20mA DC signals into 20-100kPa pneumatic signals, to communicate with electric unit instruments and pneumatic unit instruments to work together. Next, I will give you a brief introduction to Sinamics Converters.

What are Sinamics Converters?

The emergence of various types of Sinamics Converters has greatly expanded the scope of use of various instruments (devices), making the automatic control system more flexible and adaptable. The basic function of various Sinamics Converters is to convert information into a form that is convenient for transmission and processing. It is required that the information does not undergo distortion, distortion, delay, etc. during the conversion process. Therefore, the linearity, input and output impedance matching, and isolation of basic drive technology functions have certain requirements.

1. Linear characteristics. It is required that the output signal Y of Sinamics Converters and the input signal X have a good proportional relationship, that is, Y=KX+A, where K and A are constants.

2. Input impedance and output impedance. Sinamics Converters' input impedance and output impedance must match the input and output instrumentation to obtain high conversion accuracy.

3. Isolation characteristics. The input circuit, output circuit, and power circuit should be isolated from each other on the DC potential, and the grounding points of the input and output circuits F should be separated to improve the anti-interference ability.

What Sinamics Converters are for and how they work.

Sinamics Converters are designed and work according to the principle of force balance. There is a coil inside it. When the current signal of the regulator (transmitter) is sent to the coil, due to the action of the internal permanent magnet, the coil and the lever are displaced, driving the baffle close to (or away from) the nozzle, causing nozzle back pressure Increased (or decreased), this back pressure acts on the internal pneumatic power amplifier, the amplified pressure is fed one way to the output of the Sinamics Converters and the other way is fed to the feedback bellows. The pressure delivered to the feedback bellows generates a reverse displacement at the other end of the iron core through the force transmission of the lever. When this displacement is balanced with the electromagnetic torque generated by the input signal, the input signal, and the output pressure are in a one-to-one proportional relationship. That is when the input signal changes from 4mA.DC to 20mA.DC, the output pressure of low voltage converters， Medical Solutions changes from 0.02 to 0.1MPa, realizing the process of converting the current signal into a pneumatic signal. The zero adjustment mechanism is used to adjust the zero position of Sinamics Converters, and the feedback bellows acts as feedback.
