The Bosch Rexroth Indramat VT-SSPA1-508-22/V0 proportional amplifier, part of the VT-SSPA Plugin Proportional Amplifiers series, delivers high-precision control for demanding industrial automation tasks. This unit, designated VT-SSPA1-508-22/V0, operates on a nominal Operating Voltage of 24 V DC and supports a Maximum Current Range of 0–2.6 A with a factory-set Nominal Current of 2.5 A. It accepts a wide Proportional Command Voltage Range of 0–10 V and a Switching Command Voltage Range of 12–35 V, ensuring compatibility with diverse control schemes. The amplifier’s default Biasing Current Factory Setting is 100 mA, adjustable across a full Biasing Current Range (Ib) of 0–350 mA for fine-tuned performance. With a lightweight design of Weight 0.125 kg, the VT-SSPA1-508-22/V0 combines compact form factor with robust functionality for precision applications.
Performance features include adjustable Ramp Time Standard Range from 100 ms to 5 s and an optional Ramp Time High-Rate Range of 60 ms to 5 s, enabling tailored response dynamics. The device maintains stable output under varying loads thanks to a Minimum Coil Inductance of 15 mH and tolerance for Maximum Cable Inductance up to 100 µH. At peak output, the amplifier handles switching commands at a Clock Frequency at Imax of 305 Hz, supporting rapid control loop cycling. The integrated Resistance of 20 kΩ ensures precise voltage division, while the robust Connection scheme—four screw terminals accommodating cable diameters of 4.5–11 mm—facilitates secure installation. Such technical attributes yield consistent current regulation, minimal thermal drift, and high-fidelity signal tracking across the full operating envelope.
Designed for seamless integration into hydraulic control systems and broader industrial automation networks, the VT-SSPA1-508-22/V0 delivers exceptional reliability and durability. Its compact dimensions and lightweight build simplify retrofit and maintenance operations, reducing system downtime. Conforming to Bosch Rexroth Indramat’s stringent quality standards, the amplifier withstands demanding factory environments, ensuring stable performance over extended duty cycles. The versatile command voltage inputs and configurable biasing range make it ideally suited for proportional valve control, motion control feedback loops, and process regulation tasks. Overall, the VT-SSPA1-508-22/V0 embodies a dependable, high-precision solution for modern industrial control applications.
