Product Description:

The VT-MRPA2-2-11/V0/0 is an Electronic valve amplifier designed by Bosch Rexroth Indramat for precise control of proportional hydraulic valves. This valve amplifier is designed to be easily integrated into industrial automation systems, thanks to its modular design and DIN-rail mountability.

With its 1.5A maximum current limitation and support for both ±10V and 4-20mA analog command inputs, the VT-MRPA2-2-11/V0/0 valve amplifier offers versatile control possibilities. To operate proportional valves with one or two solenoid designs, the amplifier produces a pulse width modulation (PWM) signal whose frequency can be adjusted. Digital input/output (I/O) interfaces built within the amplifier allow for better system monitoring via the provision of enable and status feedback signals. There is no need for additional hardware to check the system's performance thanks to the built-in test jacks. There is a wide range of control systems that are compatible with this valve amplifier since it has a voltage signal input range of ±10V and a current input range of 4-20mA. The precise valve control provided by the PWM output is essential to the accuracy of hydraulic operations.

The VT-MRPA2-2-11/V0/0 electric valve amplifier's modular design makes it easy to set up and keep running. Efficient energy utilization is guaranteed by its capability for solenoid drive output with PWM control. It is possible to place this valve amplifier on DIN rails, which allows it to make more efficient use of the space that is available in control cabinets. A dependable option for sophisticated hydraulic control applications, the VT-MRPA2 valve amplifier robust features and is highly adaptable. It is a model of effective and precise industrial automation. With its strong control features and dependable performance, this valve amplifier is perfect for hydraulic applications.
