The VT-SKWA1-5-10/V0/0 from Bosch Rexroth Indramat is a high-performance module in the VT-SSPA Plugin Proportional Amplifiers series, engineered for precision control in industrial automation. It operates at an Operating Voltage of 24 V DC, delivering reliable power for demanding proportional valve applications. The amplifier features an adjustable Ramp Time from 60 ms to 5 s, allowing users to tailor response dynamics to specific system requirements. With a Biasing Current (adjustment) range of 0–300 mA and an ingress protection rating of IP65, this compact unit weighs just 0.125 kg, combining robustness with a minimal footprint. The design emphasizes durability and adaptability, ensuring consistent performance in harsh operating environments.
Technically, the VT-SKWA1-5-10/V0/0 maintains a Nominal Current (factory) draw of 1.2 A under normal conditions, with a Maximum Current (adjustment) capability of up to 1.8 A. Its Input Impedance of 20 kΩ reduces loading on control circuitry and preserves signal integrity over long cable runs. The amplifier accepts a Command Input (Proportional) signal of 0–10 V for fine flow or force control, as well as a Command Input (Switching) threshold ranging from 12 V to supply voltage for discrete valve activation. It supports a Maximum Command Value of 35 V, ensuring compatibility with a broad spectrum of control systems. Cable entry is designed for diameters between 4.5–11 mm, accommodating flexible installation options without compromising sealing.
Operationally, the VT-SKWA1-5-10/V0/0’s adjustable Biasing Current (adjustment) allows precise compensation for valve deadband and friction, while the factory default Biasing Current (factory) of 0 mA ensures a neutral starting point. Operators can finely tune the bias to achieve consistent baseline output and smooth dynamic response. The variable Ramp Time range further enhances performance by mitigating system oscillations during load changes or rapid setpoint shifts. Rated for an Operating Temp. Range of –25 °C to +70 °C, this amplifier sustains reliable operation across extreme temperature fluctuations. Its Ingress Protection of IP65 guarantees resistance to dust and water jets, minimizing downtime in challenging environments.
Integration flexibility is provided via dual connection methods: four-screw terminals or an industry-standard 4-pin M12 connector, simplifying field wiring and maintenance. The VT-SKWA1-5-10/V0/0 seamlessly interfaces with proportional valves and PLC-based control architectures, facilitating plug-and-play deployment. Its compact weight and robust housing support installation in confined enclosures or mobile platforms. Ideal for applications in machine tooling, material handling, and process control, this amplifier enhances system precision and responsiveness, delivering consistent performance in a variety of industrial sectors.
