Available. VT-VRPA_1-527-10_V0_RTP. The Bosch Rexroth VT-VRPA1-527-10/V0/RTP is a high-performance electric amplifier designed for precise hydraulic valve control in industrial automation systems. This amplifier features a proportional solenoid with an external amplifier, delivering responsive and accurate positioning of directional spool valves. It operates with a nominal 24 VDC supply and supports a fluid temperature range from –20°C to +80°C, compliant with the DIN 51524 hydraulic fluid standard. The amplifier is housed in a compact subplate format with standard ISO interfaces, ensuring easy integration into existing hydraulic circuits. Its IP65 rating provides protection against dust and water ingress, making it suitable for demanding industrial environments. The VT-VRPA1-527-10/V0/RTP is engineered for longevity and reliability, offering exceptional precision with a hysteresis of less than 1% and PID position control with external ramp adjustment. It supports nominal flow rates of 80 L/min for NG10 and 2.6/10/35 L/min for NG6 subplate configurations, with a pressure drop of 4–8 bar across control ports. The amplifier's maximum power consumption is 40 W, and it can handle a solenoid maximum current of 2.7 A, ensuring energy efficiency without compromising performance. Designed for seamless integration, the amplifier features mounting hole configurations compliant with ISO 4401-05-04-0-94 for NG10 and ISO 4401-03-02-0-94 for NG6, facilitating straightforward installation. It operates reliably across ambient temperatures from –20°C to +50°C and tolerates up to 90% relative humidity without performance degradation. The VT-VRPA1-527-10/V0/RTP is ideal for applications requiring precise fluid power control, such as packaging machines, mobile equipment, and industrial presses, ensuring consistent and accurate valve positioning in automated systems.
