Product Description:

The VT 10681 Proportional Amplifier Card, manufactured by Bosch Rexroth Indramat, is a high-performance industrial automation part. This card is designed to offer dependable control options for tasks that need precise control of position or speed in industrial automation systems.

The VT 10681 proportional amplifier card includes a PID control circuit that allows for three different modes of control that are proportional, integral, and derivative. This makes it possible to fine-tune the system's settings to get the best performance. The card's coil resistance is set at 2000 Ω, and its internal control voltage can be anywhere from 0V to 10V. The card allows users to set the output current to either ± 60 mA or ± 100 mA, which lets them change how responsive the system is. Three internal potentiometers make it easy to change the PID values using the controls on the faceplate. The card also has an ammeter fixed on the faceplate that makes it easy to check how well the system is working by giving a quick visual reference for valve current.

The VT 10681 amplifier card works effectively as long as the temperature does not exceed 50°C. Its power source current is less than 200 mA. The voltage of the power supply is controlled so that it stays between ±22V and ±28V DC. This makes sure that the power supply is safe and stable. It can be stored at temperatures between -20°C and 70°C. The amplifier card has a built-in voltage stabilizer that makes sure the voltage source is clean and stable so that it can always work. This VT amplifier card is an important part of automated control systems because it is flexible and built to last.
