Product Description:

The VT-MRPA1-1-10/V0/0 by Bosch Rexroth is a robust analogue amplifier suitable for controlling direct-operated proportional directional valves. It enables precise regulation of hydraulic flow and pressure, providing dynamic control over valve positioning and enhancing system responsiveness. This amplifier is ideal for applications that demand fine-tuned hydraulic control, ensuring accurate flow control for improved productivity and energy efficiency. With a command value input range of 0 to 10 V, the amplifier offers compatibility with a broad range of system configurations. This makes it easy to integrate into different setups. It also comes in a compact 40 x 79 x 85.5 mm design and a weight of only 0.14 kg, making it easy to handle and install.

The outputs on the VT-MRPA1-1-10/V0/0 range from 0 to 2.5 A, providing precise control over the current supplied to the proportional directional valves. These outputs are protected against potential damage caused by short circuits, a common issue in electrical systems. The clocked output operates at an approximate frequency of 5 kHz, allowing for fast and responsive control, especially in systems that require high-speed operation. This amplifier operates with minimal electrical load and boasts a current consumption of less than 2 A. This makes it an excellent choice for cost-conscious and energy-efficient setups that require optimal performance with minimal energy demands.

The VT-MRPA1-1-10/V0/0’s 12 screw terminals offer seamless connectivity with other devices, ensuring a firm, stable connection for each input and output signal. This unit is suited for Top Hat rail mounting (TH 35-7.5) in accordance with EN 60715 standards, ensuring easy and secure installation in control panels or electrical enclosures.
