Product Description:

Bosch Rexroth Indramat created the VT-VRPA1-51-11 proportional valve amplifier to exactly control servo solenoid valves. This company is a global engineering and technology company that is known for its innovations in the consumer products, industrial, and automation industries.

The VT-VRPA1-51-11 proportional valve amplifier requires a nominal 24V DC power source with a range of 21V to 40V DC to operate from batteries. It also works with rectified AC voltage (Ueff = 21–28V, single-phase). It has outputs that are resistant to short circuits and overcurrent safety to make sure it works well. The amplifier is equipped with diagnostic features, such as the capability to locate open circuits in feedback signal lines and low voltages. Indicators of status allow you to check items in real time. A green LED indicates that the device is turned on, a yellow indicates that the feedback signal is open, and a red LED indicates that there is an error with the voltage at the input. Considering these characteristics, the amplifier is an excellent option for usage in CNC machines and servo-hydraulic applications.

Two more features of the VT-VRPA1-51-11 are that it works with 4WRL M-3X series proportional valves and that it can be mounted on a Eurocard. These features make it easy to add to current systems and keep a high level of accuracy in hydraulic motion control. The improved diagnostics and protection features of the amplifier make the system more reliable and efficient. This product shows how dedicated Bosch Rexroth is to providing top-notch automation options for industries.
