An analog amplifier card, the Bosch Rexroth VT-VRRA 1-527-20/V0, has been successfully added to our portfolio of industrial electronics repairs. This module is a key control element in hydraulic systems that require maximum precision and fast valve response.
What is the purpose of this card?
The VT-VRRA series amplifier cards are designed to control high-speed servo-valves and proportional directional valves (e.g., the 4WRPH6 or 4WRL series). They process the analog control signal and provide precise power supply to the valve coils, ensuring continuous monitoring of their actual position via electrical feedback.
