VT-VSPA 1-525-10/V0/RPT
The Bosch Rexroth Indramat VT-VSPA 1-525-10/V0/RPT is a high-performance unit in the VT-VSPA Proportional Amplifiers series designed for precise control in industrial automation. Rated for an operating voltage of UB 24 VDC +40%/-20%, this amplifier draws under 50 VA of power consumption and delivers a 2.5 A peak current for demanding proportional valve applications. With a ramp time range of 20 ms to 5 s (switchable to 0.2 to 50 s), it enables smooth and customizable signal transitions. Primary function: to regulate hydraulic or pneumatic valve positioning via analog or current command signals.
Featuring a 48-pin male (DIN 41612, design F) connector type, the VT-VSPA 1-525-10/V0/RPT supports multiple analog inputs: differential command values 1–4 at ±10 V, Re >100 kΩ, current input (command value 6) at 4–20 mA, Re =100 Ω, and differential command value 5 at ±10 V, Re >50 kΩ. It operates up to 2 A current consumption and generates an output command signal of ±10 V, ±2% accuracy. A unique reverse polarity protection feature safeguards the unit from miswiring, while integrated clock frequency selection (300 to 370 Hz for valve type Wra6.2x) and a z20 monitor signal input provide advanced ramp monitoring and diagnostics.
The amplifier’s Eurocard (100 x 160 mm) form factor and net weight of 0.17 kg ensure easy integration and minimal panel space. It maintains stable operation across an operating temperature range of 0 to 50 °C and can endure storage temperatures from –25 to +85 °C, demonstrating excellent durability. Valve hysteresis remains under 2% for high precision. The device’s robust design and consistent performance under varied environmental conditions make it an ideal choice for industrial applications, offering enhanced efficiency, reliability, and ease of maintenance in hydraulic control systems.
