VT-RK5-30
The VT-RK5-30 from Bosch Rexroth Indramat is a high-performance member of the VT-SSPA Plugin Proportional Amplifiers series, delivering precise output control in demanding industrial automation environments. This compact amplifier operates at 24 V DC and features an IP65 protection rating to ensure reliable performance in harsh conditions. With a nominal current of 1.6 A and an adjustable ramp time range from 100 ms to 5 s, it provides rapid response and smooth actuation for proportional valves. Its robust design and secure connections make it ideal for integration in motion control systems, offering flexibility and consistency across a variety of applications. The amplifier supports a wide current output adjustment range up to 1.7 A, enabling fine-tuning of actuator behavior in precision systems.
Equipped with advanced electrical features, the VT-RK5-30 offers an adjustable biasing current range of 0…300 mA with a factory setting at 100 mA, allowing engineers to optimize valve opening characteristics. The minimum coil inductance requirement of 15 mH ensures compatibility with a broad array of proportional valves and prevents instability in low-inductance loads. At full load, the amplifier sustains a clock frequency of 340 Hz, maintaining constant performance during high-demand cycles. Control inputs accommodate both a proportional command range of 0–10 V and a switching command range from 12 V to UB, ensuring seamless integration with standard PLC and analog control systems. An input resistance of 20 kΩ minimizes signal loss and ensures precise voltage-to-current conversion under varying load conditions.
Operationally, the VT-RK5-30 excels in resilience and ease of use. Its dual cable connection options—4 screw terminals and a 4-pin M12 connector (M12×1)—provide secure, vibration-resistant wiring in confined machine enclosures. The unit accepts cable diameters from 4.5 mm to 11 mm, accommodating a variety of harness designs without additional adaptors. Designed to withstand temperature extremes from –25 °C to +70 °C, the amplifier continues to deliver consistent performance in both freezer-like and high-heat production zones. With EN 60529 IP65 certification, it resists dust ingress and powerful water jets, lowering maintenance requirements and extending service intervals.
Integration is streamlined through standardized electrical interfaces and industry-proven packaging, enabling fast mounting on DIN rails or panel surfaces. The combination of screw and M12 connectivity simplifies system layout and reduces installation time, while the broad operating voltage tolerance ensures compatibility with common DC supply buses. Ideal for proportional valve control in hydraulic systems, the VT-RK5-30 enhances motion smoothness and throughput in packaging machinery, presses, and metal forming applications. By delivering precise current control and robust protection, this amplifier elevates the performance and reliability of automated equipment across diverse industrial sectors.
