Product Description:

The VT-KRRA 2-527-20/V0/2CH is a versatile electric amplifier suited for 2-axis control in presses, forming machines, and machine tools. It is designed by Bosch Rexroth to support the simultaneous operation of two high-response valves. This design allows the amplifier to control two independent axes at the same time, making it ideal for systems that require precise coordination between multiple axes. It can process and output signals for both axes simultaneously, ensuring synchronized movement and response. This amplifier card comes with a controlled output stage, which allows the amplifier to maintain a consistent, controlled flow of power, even in dynamic operating conditions. This leads to smoother control, enhancing overall system reliability.

For enhanced stability, the amplifier features short-circuit-proof outputs that are designed to automatically disconnect or shut down in case of a faulty circuit. This helps to prevent excessive current from damaging the system for enhanced durability. Each valve is rated for a maximum current consumption of 1.5 A and a maximum power consumption of 37 VA. This power efficiency contributes to lower operational costs and ensures that the amplifier can be used in a wide range of environments without excessive power demand. This unit boasts a maximum 2.9 A solenoid current that allows it to handle demanding applications, where quick and accurate valve movements are critical.

The VT-KRRA 2-527-20/V0/2CH features a plug-in connection, providing a secure and standardized interface for connecting the amplifier to the control system. The valve and supply connections are made via a screw-plug-in connection on the handle side, which simplifies the installation and maintenance process. The amplifier can withstand temperatures of up to 70°C, permitting installation even in extreme environments without risk of damage to the unit or connected components.
