Description

The VT 2000-52-A is made by Rexroth, Indra and Bosch in the VT-2000 series. The VT-2000 is a proportional amplifier suitable for controlling single electromagnetic pressure control valves without electrical position feedback. This VT 2000-52-A is supplied with a factory specified nameplate with a pulse frequency of 100 Hz or 200 Hz; ±10%, operating voltage 24vdc + 40%-5%, connection type 32 pin male connector, DIN 41612, form D.

The VT2000-52-A proportional amplifier is an electronic device that amplifies the voltage or current of an input signal and outputs the amplified signal proportionally. It is commonly used in control systems to amplify the weak signal generated by a sensor or controller to a level sufficient to drive an actuator or other load.

The VT2000-52-A proportional amplifier works on the basis of negative feedback control, which adjusts the size of the output signal by comparing the difference between the input signal and the output signal. When the input signal changes, the proportional amplifier will adjust the size of the output signal proportionally according to the change degree of the input signal, so as to achieve accurate control of the controlled object.

VT2000-52-A proportional amplifiers typically feature high gain, low offset, high linearity and fast response to provide precise control performance in a variety of applications. They are widely used in industrial automation, aerospace, automotive electronics, medical equipment and other fields.

Choosing the right proportional amplifier needs to consider the following factors:

1. Gain range: The gain range of the proportional amplifier should meet the application requirements. For high-gain applications, a proportional amplifier with high gain needs to be selected, while for low-gain applications, a proportional amplifier with low gain can be selected.

2. Input impedance: The input impedance of the proportional amplifier should match the input signal source. For a high-impedance signal source, a proportional amplifier with a high input impedance needs to be selected, while for a low-impedance signal source, a proportional amplifier with a low input impedance can be selected.

3. Output impedance: The output impedance of the proportional amplifier should match the output load. For low impedance loads, a proportional amplifier with low output impedance needs to be selected, while for high impedance loads, a proportional amplifier with high output impedance can be selected.

4. Linearity: The linearity of the proportional amplifier should meet the application needs. For high-precision applications, a proportional amplifier with high linearity needs to be selected, while for general precision applications, a proportional amplifier with low linearity can be selected.

5. Common mode rejection ratio: The common mode rejection ratio of the proportional amplifier should meet the application needs. For high common-mode signal environments, a proportional amplifier with a high common-mode rejection ratio needs to be selected, while for low common-mode signal environments, a proportional amplifier with a low common-mode rejection ratio can be selected.

6. Noise level: The noise level of the proportional amplifier should meet the application needs. For low noise applications, a proportional amplifier with a low noise level needs to be selected, while for high noise applications, a proportional amplifier with a high noise level can be selected.

7. Operating temperature range: The operating temperature range of the proportional amplifier should meet the application requirements. For applications that need to operate over a wide temperature range, a proportional amplifier with a wide operating temperature range needs to be selected, while for applications that operate over a specific temperature range, a proportional amplifier with a narrow operating temperature range can be selected.

8. Package form: The package form of the proportional amplifier should meet the application needs. For applications that need to work in harsh environments, a proportional amplifier with a robust package form needs to be selected, while for applications that work in general environments, a proportional amplifier with a plain package form can be selected.
