Indramat VT-2000
The VT-2000 amplifiers are designed for precision control of both direct and pilot-operated proportional pressure control valves, particularly those lacking electrical position feedback. These amplifiers offer several key features to facilitate effective control, including a differential input and an additional command value input ranging from 0 to +9 V. Moreover, they feature a ramp generator that can be independently adjusted for both up and down ramps, ensuring smooth and customizable operation. The inclusion of a clocked current output stage enhances reliability and accuracy in controlling valve operation. Additionally, built-in safeguards such as reverse polarity protection for the voltage supply and short-circuit protection for the solenoid cable contribute to the durability and safety of the amplifiers in industrial environments.
