Product Description:

The Bosch model VT-VRPA1-527-10/V0/QV is a remarkable Amplifier Card Module which is a highly efficient and reliable component designed for precision hydraulic control. Bosch has a strong reputation for creating cutting-edge reliable products that are widely used in industrial automation and commercial domains.

This VT-VRPA1-527-10/V0/QV amplifier card module contains a 4/3 load sensing proportional design and helps to ensure direct proportional flow control by making it ideal for applications requiring responsive hydraulic operations. The amplifier module is designed with pressure-compensated hydraulic control by allowing for stable and consistent performance. It integrates solenoid control with an extractable coil which enhances flexibility in maintenance. Also, this module includes manual override options which are available in both push-button and screw-type configurations. This aids in providing an added level of operational control in case of system failures. This VT-VRPA series amplifier module supports EN 175301-803 as DIN 43650 and DT04-2P connection types to ensure compatibility with various systems. The spool position is found neutral-central which means the valve remains centered when not activated by preventing unintended movements and maintaining operational safety. Operating at 24 VDC, this directional valve-type module is a proficient choice for high-precision hydraulic systems.

This VT-VRPA1-527-10/V0/QV amplifier card module module is designed with return springs found in de-energized condition by allowing it to maintain position holding when necessary. The module is nickel-plated and burnished by offering excellent resistance to corrosion. It features wet pin tubes for DC coils by ensuring long-term working in industrial environments. It is crucial to avoid using connectors with free-wheeling diodes or LED lamps when connecting the solenoids as this could impact its functioning.
